Signal Specification
General
All the values given below are between the respective terminal in column 1 and terminal #A6 in column 1 (power ground), if this is not the case, it is indicated within brackets.
NOTE:
It is important to check ground terminals before taking readings.
| U= | DC voltage in volts (V) | UAC = | AC voltage in volts (V) |
| Ubat = | Battery voltage (V) | f = | Frequency in Hertz (Hz) |
| Ulow = | Voltage approximately 0 V | t = | Time in seconds |
| PWM = | Pulse width modulated signal as a % | - | - |
