Signal Specification
All the values given below are between the respective terminal in column 1 and terminal #C1-2 in column 2 (power ground) unless otherwise stated in parenthesis after the table entry.
NOTE:
It is important to connect the breakout box and check the ground connections before starting to measure.
| 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 in % | % duty = | Duty cycle (pulse ratio) in percent (%) |
