Martel Electronics 3001 - Manual (Page 29)

5. Isolated Inputs
5.1 Voltage Input
The 3001 can measure DC voltages from 0 V to 100 V, using the following two ranges for
maximum accuracy: 10 V, and 100 V.
a) Disconnect any test leads from external devices.
b) Press the key to select isolated DC voltage and current input mode, if not
already selected. If the desired DC voltage mode is not displayed, press the key
again to cycle to the desired DC voltage mode.
c) Connect the unit under test to the isolated voltage/current input terminals of the 3001
as shown in figure 17.

5.2 Current Input
The 3001 can measure DC current from 0 mA to 50 mA.
a) Disconnect any test leads from external devices.
b) Press the key to select isolated DC voltage and current input mode, if not
already selected. If the DC current mode is not displayed, press the key again to
cycle to it.
c) Connect the unit under test to the isolated voltage/current input terminals of the 3001
as shown in figure 18.
