Isolated Inputs
Voltage Input 3
3-3
Voltage Input
The Product can measure dc voltages from 0 V to 100 V. Use these ranges for maximum
accuracy: 10 V and 100 V.
1. Disconnect test leads from external devices.
2. Push  to select isolated dc voltage and current input mode, if not already selected.
If the necessary dc voltage mode is not shown, push  again to cycle to the
necessary dc voltage mode.
3. Connect the unit under test (UUT) to the isolated voltage/current input terminals of
the Product as in Figure 3-1.
