Model 2303-PJ 500mA range current readback accuracy limits
Digital voltmeter input accuracy
Follow the steps below to verify that Model 2303, 2303B, and 2303-PJ digital voltmeter input
accuracy is within specified limits. The test involves setting the voltage applied to the DVM
input to accurate values and then verifying that the Model 2303 digital voltmeter input readings
are within required limits.
1.
With the power off, connect the Model 2303 DVM IN terminals to OUTPUT SOURCE
terminals and the digital multimeter, as shown in Figure 1-6. Be sure to observe proper
polarity (DVM IN + to and DMM INPUT HI; DVM IN - to SOURCE - and
DMM INPUT LO).
