4. Measuring an External Power Supply with Current-source voltage-measurement (ISVM)
When an external voltage is measured with Auto range by following the procedure below, Auto range
detects overload (OVL) and sets the Standby status.
1. Set the current-source to 0 A and the limiter voltage to ±5 V.
The VM (voltage-measurement) range at ISVM (Current-Source Voltage Measurement) is set
to the same value as the range of the voltage-limiter.
2. Connect the external power supply at 2 V.
The 2 V connection causes Auto range to set the measurement range to 3 V. Then the volt-
age-limiter is also changed to the 3 V range. Therefore, the internal value ±3.219 V is set.
