## Reading Strategy
|
|
|
29
|
|
|
|
30
|
Working interpretation of the two documents:
|
|
|
31
|
|
|
|
32
|
- the English manual is the easier baseline for product behavior and software workflow
|
|
|
33
|
- the Chinese manual is newer and appears to supersede or extend some product details
|
|
|
34
|
- when the two overlap, treat the Chinese manual as the newer reference unless runtime evidence says otherwise
|
|
|
35
|
|
|
|
36
|
## Confirmed Model Split
|
|
|
37
|
|
|
|
38
|
- `TC66` supports USB communication only
|
|
|
39
|
- `TC66C` supports USB and Bluetooth communication
|
|
|
40
|
- Android and iPhone app support are described only for `TC66C`
|
|
|
41
|
- PC software communicates with `TC66` and `TC66C` by `micro-USB`, not Bluetooth
|
|
|
42
|
|
|
|
43
|
This split is one of the most important conclusions from the manuals.
|
|
|
44
|
|
|
|
45
|
## Confirmed Device Capabilities
|
|
|
46
|
|
|
|
47
|
- display: `0.96 inch` color `IPS`
|
|
|
48
|
- screen resolution: `160 x 80`
|
|
|
49
|
- voltage measurement range: `0.0050 V` to `30.0000 V`
|
|
|
50
|
- current measurement range: `0` to `5.00000 A`
|
|
|
51
|
- supply voltage: `3.5 V` to `24 V`
|
|
|
52
|
- power range: `0` to `150 W`

|
|
|
55
|
- capacity accumulation: `0-99999 mAh`
|
|
|
56
|
- energy accumulation:
|
|
|
57
|
- older English manual: `0-99999 mWh` and `999.99 Wh`
|
|
|
58
|
- newer Chinese manual still speaks in `mWh`/`Wh` terms but does not restate the full line in the same layout
|
|
|
59
|
- load impedance range:
|
|
|
60
|
- English manual: `1 Ω` to `9999.9 Ω`
|
|
|
61
|
- Chinese manual confirms load impedance display but not all values in the same line block
|
|
|
62
|
- temperature range:
|
|
|
63
|
- measurement / working range in manuals centers on `0 C` to `45 C`
|
|
|
64
|
- refresh rate: `2 Hz`
|
|
|
65
|
|
|
|
66
|
## Product-Specific Behavior
|
|
|
67
|
|
|
|
68
|
- this is a `Type-C` tester rather than the older USB-A style family
|
|
|
69
|
- the product has hardware switches for:
|
|
|
70
|
- system power
|
|
|
71
|
- `PD`
|
|
|
72
|
- there is also a `micro-USB` port for isolated power or PC connection
|
|
|
73
|
- the manuals stress an important operating rule:
|
|
|
74
|
- turn `PD` or `CC pull-down` off during normal charging measurements
|
|
|
75
|
- turn it on for trigger and fast-charge protocol detection
|
|
|
76
|
|
|
|
77
|
## UI and On-Device Pages
|
|
|
78
|
|
|
|
79
|
The manuals describe eight default device pages:
|
|
|
80
|
|
|
|
81
|
- main measurement
|
|
|
82
|
- offline recording
|
|
|
83
|
- quick-charge recognition
|
|
|
84
|
- quick-charge protocol detection
|
|
|
85
|
- trigger / decoy
|
|
|
86
|
- system settings
|
|
|
87
|
- system information
|
|
|
88
|
- simple measurement
|
|
|
89
|
|
|
|
90
|
### Main measurement page
|
|
|
91
|
|
|
|
92
|
- shows voltage, current, capacity, energy, temperature, data-group number, load impedance, power, and current direction
|
|
|
93
|
- long press `K1` clears the active data group
|
|
|
94
|
- long press `K2` switches the data group
|
|
|
95
|
|
|
|
96
|
### Data-group behavior
|
|
|
97
|
|
|
|
98
|
- the manuals describe multiple data groups with `0` as a temporary group
|
|
|
99
|
- group `0` restores and flashes the previous totals after reboot, then clears once accumulation exceeds `1 mAh`
|
|
|
100
|
- at least group `1` persists totals across power cycles
|
|
|
101
|
- the wording in the English manual appears truncated around group numbering, so group semantics should be verified on-device before we hard-code exact persistence rules for every group
|
|
|
102
|
|
|
|
103
|
### Offline recording page
|
|
|
104
|
|
|
|
105
|
- records measurements into onboard storage
|
|
|
106
|
- configurable recording interval: `1` to `60` seconds
|
|
|
107
|
- total recording duration ranges roughly from `24 minutes` to `24 hours`, depending on interval
|
|
|
108
|
- recording pauses automatically after power loss
|
|
|
109
|
- stored data can be cleared from the device menu
|
|
|
110
|
|
|
|
111
|
### Quick-charge recognition
|
|
|
112
|
|
|
|
113
|
- reports `D+` and `D-` levels
|
|
|
114
|
- recognizes at least:
|
|
|
115
|
- `QC2.0`
|
|
|
116
|
- `QC3.0`
|
|
|
117
|
- Apple `2.4A / 2.1A / 1A / 0.5A`
|
|
|
118
|
- `Android DCP`
|
|
|
119
|
- `Samsung`
|
|
|
120
|
- manuals say recognition is only a reference indication
|
|
|
121
|
|
|
|
122
|
### Protocol detection
|
|
|
123
|
|
|
|
124
|
- dangerous operation that can make the USB-C side output high voltage
|
|
|
125
|
- manuals say to disconnect the load before running detection
|
|
|
126
|
- supported auto-detection includes:
|
|
|
127
|
- `QC2.0`
|
|
|
128
|
- `QC3.0`
|
|
|
129
|
- Huawei `FCP`
|
|
|
130
|
- Huawei `SCP`
|
|
|
131
|
- Samsung `AFC`
|
|
|
132
|
- `PD`
|
|
|
133
|
|
|
|
134
|
### Trigger / decoy
|
|
|
135
|
|
|
|
136
|
- supported trigger families include:
|
|
|
137
|
- `QC2.0`
|
|
|
138
|
- `QC3.0`
|
|
|
139
|
- Huawei `FCP`
|
|
|
140
|
- Huawei `SCP`
|
|
|
141
|
- Samsung `AFC`
|
|
|
142
|
- `PD2.0`
|
|
|
143
|
- `PPS`
|
|
|
144
|
- `PD` mode allows switching supported voltages and adjusting step value for `PPS`
|
|
|
145
|
- after most trigger modes, unplugging and replugging is required to return to `5 V`
|
|
|
146
|
|
|
|
147
|
### Settings
|
|
|
148
|
|
|
|
149
|
- auto screen-off:
|
|
|
150
|
- `0-9` minutes
|
|
|
151
|
- `0` means always on
|
|
|
152
|
- brightness:
|
|
|
153
|
- Chinese manual says `10` levels
|
|
|
154
|
- temperature unit:
|
|
|
155
|
- `C` / `F`
|
|
|
156
|
- PC communication switch
|
|
|
157
|
- Bluetooth switch
|
|
|
158
|
- screen rotation
|
|
|
159
|
- `PD` software switch / `CC line mode`
|
|
|
160
|
- language choice
|
|
|
161
|
- restore factory settings
|
|
|
162
|
|
|
|
163
|
Important behavior from the newer Chinese manual:
|
|
|
164
|
|
|
|
165
|
- enabling `CC pull-down` can auto-light the screen on PD chargers
|
|
|
166
|
- `CC pull-down` may affect normal charging measurement
|
|
|
167
|
- if measuring PD charging behavior, turn `CC pull-down` off
|
|
|
168
|
- if doing protocol detection or trigger, `CC pull-down` must be on and no load should be connected
|
|
|
169
|
|
|
|
170
|
## System and Recovery Notes
|
|
|
171
|
|
|
|
172
|
- system info page includes serial number, firmware version, boot count, and current runtime
|
|
|
173
|
- abnormal-state recovery:
|
|
|
174
|
- hold `K2` during power-on to restore factory settings
|
|
|
175
|
- hold `K1` during power-on to enter boot mode for firmware update
|
|
|
176
|
|
|
|
177
|
## PC Software
|
|
|
178
|
|
|
|
179
|
- supported OS:
|
|
|
180
|
- Chinese manual: `Windows 7` to `Windows 10`
|
|
|
181
|
- English manual: `Windows 7 and above`
|
|
|
182
|
- PC communication is via `micro-USB`
|
|
|
183
|
- manuals mention `RuiDengUSBMeter` desktop software
|
|
|
184
|
- first-time use requires driver installation
|
|
|
185
|
- firmware update is performed from PC software while booting the device into update mode
|
|
|
186
|
|
|
|
187
|
Important workflow details:
|
|
|
188
|
|
|
|
189
|
- avoid USB hubs with compatibility issues; prefer a native computer USB port
|
|
|
190
|
- offline data can be downloaded into the PC application
|
|
|
191
|
- viewing offline data pauses real-time curve recording
|
|
|
192
|
- the graph can export table and image data
|
|
|
193
|
- manual software version references:
|
|
|
194
|
- English manual: `V1.0.0.5`
|
|
|
195
|
- newer Chinese manual: `V1.0.0.6`
|
|
|
196
|
|
|
|
197
|
## Android App
|
|
|
198
|
|
|
|
199
|
- Android support:
|
|
|
200
|
- English manual: `Android 5.0+`
|
|
|
201
|
- newer Chinese manual narrows expectation to `Android 5.0-10.0`
|
|
|
202
|
- Bluetooth requirement: `BLE 4.0+`
|
|
|
203
|
- app support is only for `TC66C`
|
|
|
204
|
- Android `6.0+` requires location permission for BLE scanning
|
|
|
205
|
- BLE devices must be discovered in the app, not through system Bluetooth settings
|
|
|
206
|
|
|
|
207
|
App and distribution notes:
|
|
|
208
|
|
|
|
209
|
- English manual points to Google Play search `TC66C`
|
|
|
210
|
- newer Chinese manual points to Google Play search `RuiDeng`
|
|
|
211
|
- manual also references direct download from RuiDeng download pages
|
|
|
212
|
- export of recorded data to spreadsheet form is supported
|
|
|
213
|
- version references:
|
|
|
214
|
- English manual: Android app `V1.1.1`
|
|
|
215
|
- newer Chinese manual: Android app `V1.0.3`
|
|
|
216
|
|
|
|
217
|
The version mismatch likely reflects different release snapshots rather than a contradiction in core behavior.
|
|
|
218
|
|
|
|
219
|
## iPhone App
|
|
|
220
|
|
|
|
221
|
- iPhone app only supports `TC66C`
|
|
|
222
|
- iOS support:
|
|
|
223
|
- English manual: `iOS 8.0+`
|
|
|
224
|
- newer Chinese manual: `iOS 8.0` to `iOS 14`
|
|
|
225
|
- App Store search terms differ by manual:
|
|
|
226
|
- English manual: `TC66C`
|
|
|
227
|
- Chinese manual: `TC66C`
|
|
|
228
|
- version references:
|
|
|
229
|
- English manual: `1.2.0`
|
|
|
230
|
- newer Chinese manual: `1.2.3`
|
|
|
231
|
|
|
|
232
|
## Important Scope Conclusions for This Project
|
|
|
233
|
|
|
|
234
|
- `TC66` and `TC66C` should not be treated as identical communication targets
|
|
|
235
|
- app support is explicitly `TC66C`-only
|
|
|
236
|
- Bluetooth behavior for `TC66C` is explicitly `BLE`, not classic serial Bluetooth
|
|
|
237
|
- desktop integration for the `TC66` family is explicitly USB-based
|
|
|
238
|
- `PD` / `CC pull-down` state is likely relevant to what users see and may affect how measurements behave
|
|
|
239
|
|
|
|
240
|
## Implementation-Relevant Concepts
|
|
|
241
|
|
|
|
242
|
Concepts likely worth reflecting in app state or decoding assumptions:
|
|
|
243
|
|
|
|
244
|
- active page
|
|
|
245
|
- active data group
|
|
|
246
|
- temporary vs persistent accumulation behavior
|
|
|
247
|
- offline recording state and interval
|
|
|
248
|
- quick-charge recognition result
|
|
|
249
|
- protocol-detection support matrix
|
|
|
250
|
- trigger protocol and selected voltage
|
|
|
251
|
- `PD` or `CC pull-down` switch state
|
|
|
252
|
- Bluetooth enabled / disabled state on `TC66C`
|
|
|
253
|
- firmware version and serial number
|
|
|
254
|
|
|
|
255
|
## Open Questions
|
|
|
256
|
|
|
|
257
|
- exact data-group count and persistence behavior across all groups on current firmware
|
|
|
258
|
- whether Bluetooth payloads expose all device pages or only a subset
|
|
|
259
|
- whether the mobile apps expose offline-recording management or only live data and export
|
|
|
260
|
- whether English and Chinese manuals map to distinct firmware branches or only different documentation snapshots
|
