Connecting Cables To Terminals - Extech Instruments PRC50 User Manual

5 Source
The calibrator can source a DC voltage, DC current, resistance, frequency, and pulse signal.
Warning
To avoid electrical shock, do not apply more than the rated voltage, as marked on the calibrator, between terminals or
between any terminal and earth ground. Always use the calibrator in locations with a voltage to ground value below
30Vpeak.
Caution
Do not apply any voltage to the output terminals for ranges other than 4-20mA simulating transmitter outputs.
Otherwise, the internal circuitry may be damaged.

5.1 Connecting Cables to Terminals

For DC voltage, frequency, or pulse (see Figure 5)
Step 1: Connect the black lead cable for source to the COM output terminal and the red lead cable to the "Vhz" output
terminal.
Step 2: Connect the other ends of the cables to the input of equipment under test while making sure the polarities are
correct.
For DC current (see Figure 6)
Step 1: Connect the black lead cable for source to the "mA-" output terminal and the red lead cable to the ''mA+/LOOP''
output terminal.
Step 2: Connect the other ends of the cables to the input of equipment under test while making sure the polarities are
correct.
