Current measurement accuracy
Follow the steps below to verify that Series 2600 current measurement accuracy
is within specified limits. The procedure involves applying accurate currents from
the Series 2600 current source and then verifying that Series 2600 current
measurements are within required limits.
1. With the power off, connect the digital multimeter to the Series 2600
terminals as shown in
.
2. Select the multimeter DC current function.
3. Select the Model 2602/2612 single-channel display mode.
4. Set the Series 2600 to both source and measure current by pressing the
SRC and MEAS keys, and make sure the source output is turned on.
5. Verify measure current accuracy for each of the currents listed in
(Model 2601/2602) or
(Model 2611/2612). For each
measurement:
• Select the correct source range.
• Set the Series 2600 source output to the correct value as measured by
the digital multimeter.
• If necessary, press the TRIG key to display readings.
• Verify that the Series 2600 current reading is within the limits given in
the table. It may not be possible to set the current source to the
required value. Use the closest possible setting, and modify reading
limits accordingly.
6. Repeat the procedure for negative calibrator currents with the same
magnitudes as those listed in
7. Turn the output off, change connections as shown in
, then
select the DMM volts function.
8. Repeat steps 4 through 6 for the 3A range (Model 2601/2602) or 1.5A
range (Model 2611/2612). Calculate the current from the DMM voltage
reading and characterized 0.5
Ω
resistance value.
9. For the Model 2602/2612, repeat the above procedure for the other
channel.
