When the resistance to be measured is low (R<R
N
=U
N
/1mA), the voltage generated is lower than the fixed voltage selected. In this
case, it is better to use a variable voltage and adjust U
N
to the desired value after a first resistance measurement.

The following screen appears.
There are already 3 preset voltages that can be modified in SET-UP (see §5). Use the
keys to select one of them:
Variable Voltage 1: 50V
Variable Voltage 2: 500V
Variable Voltage 3: 2500V
Otherwise, use the
keys to go to the voltage value, then use the
keys to adjust the value of the test voltage. The
adjustment is in 10V steps up to 1,000V, then in 100V steps. Keep the keys pressed to speed up the adjustment.
