Signal Specification
General
All the values indicated below are only described values, as the power supply is not permitted when the breakout box is connected.
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 as a % |
