Low range current verification (For E36312A and E36313A only)
Low range current programming and readback accuracy
These tests verify that the current programming and the LAN, GPIB or USB readback measurement functions are
within specifications. Note that the readback values over the remote interface should be identical to those displayed
on the front panel, but with maximum resolution.
1.
Turn off the power supply using the AC line switch.
2.
Connect a DMM between the (+) and (–) terminals of the output.
3.
Connect appropriate resistor in series with the (+) terminals of the power supply and (+) terminals of the DMM
as shown below.
4.
If you are using a PC to control the power supply, connect a LAN, GPIB or USB cable from the power supply to
the PC.
5.
Turn on the power supply using the AC line switch.

VOLT 6, (@<channel>; CURR 0.020, (@<channel>)
This is an example for the E36313A, 6 V, 20 mA output.
7.
Enable the output by pressing the Output ON key
OUTP ON, (@<channel>)
8.
Record the current measured by the DMM and current returned
by the SCPI MEAS:CURR?, (@channel) command query via Key-
sight Connection Expert and verify whether it is within the limits
calculated.
MEAS:CURR?, (@<channel>)
This is an example for the E36313A, 6 V, 20 mA output.
