Note: Connect the current clamp neutral directly to CIBANO 500 and not to the other end of the neutral
cable to avoid measurement errors due to the voltage drop on the cable. Alternatively you can supply
the motor from CIBANO 500 if you want or no station battery is available.
Measurement
To perform a measurement:
1. In the Settings and conditions area, enter the settings of the Timing test.
WARNING
Death or severe injury caused by high voltage or current possible
► If you use the station battery to supply the motor or the coils via CIBANO 500, do not connect
the cables to the station battery before they are connected to CIBANO 500.
► Always connect the cables first to grounded CIBANO 500 and then to the station battery.

Motor supply
Supply source Click CIBANO 500 to supply the motor with CIBANO 500.
Click External source if the motor is supplied from the station supply or
battery without any connection to CIBANO 500 or if the station battery is
connected to the VIN section and supplied, for example, via the B4 socket.
Note: We do not recommend supplying the motor with undervoltage. Doing
so does not provide any additional useful information and can cause
degradation of the motor operation over time.
