Service manual

Test Procedure 1. Set the DC Standard (Datron 4708, Option 10) Output to 0.1
DCV.
2. Set the Agilent E1326B range to 0.113 V (0.125 V with 10%
overrange) with CONF:VOLT:DC 0.1.
3. Measure the input with READ? and verify the results are within
specified limits (at the range selected for 1 PLC).
4. Repeat steps 1 through 3 for the following DC Standard voltage
settings and Agilent E1326B ranges:
E1326B

5. Remove power and disconnect test equipment.
Example:
DC Voltage Test
(DCV Input)
This example performs a DCV test for DC volts input and a power line
reference frequency of 60 Hz. Change line 80 to OUTPUT
70903;"CAL:LFR 50" for 50 Hz operation.
NOTE
When connected to the Agilent E1326B multimeter, some DC Standards
may exhibit voltage variations at the start of a measurement. The WAIT 1
statement (line 150) provides a one second wait before measurement to
allow settling of the DC Standard output.
