Equipment Requirements
Tab l e 1 is a list of the standard equipment for the performance tests.
Performance Tests
Performance tests make sure that the Product operates within the published specifications.
Fluke recommends performance tests periodically.
In this section the Product is called the DUT (device under test). Use these verification
performance tests to make sure the values indicated on the DUT correspond, as closely as
possible, with the actual measurement values.
If the product fails any part of the performance test, see Calibration Adjustment and Repair.
Visual Inspection
Before you do the performance tests:
1. Visually inspect the DUT for signs of physical damage.
If you find a problem, make notes of the damage and perform the as-found calibration
before correction.
2. Examine the test lead sockets for debris or damage. If dirt is found, gently use a cotton
swab to remove the contaminants.
3. Make sure the DUT and all test equipment have sufficient warm-up time in accordance with
the manufacturer's specifications.

To reduce thermal EMF errors, use low-thermal leads when you calibrate voltage functions and
low-resistance functions (<50 kΩ). To calibrate current functions, use the appropriately rated
cables for the current. Currents as high as 20 A will be generated. When calibrating high-
resistance functions (>50 kΩ), use shielded test leads to reduce electromagnetic interference.
RLO
To verify the resistance of earthing and equipotential bonding conductors:
1. Set all equipment and the DUT to standby mode.
2. Connect two low-thermal EMF test leads to the DUT, one at green connector (ground) and
one at yellow connector.
3. Short the two test leads together at the furthest point from the DUT.
4. Disconnect all other test leads.
5. Turn the rotary switch on the DUT to .
6. Push to zero the test leads.
If the DUT shows an error that the lead resistance cannot exceed 3 Ω, recheck that the
leads have good contact and try again.
Note
When zeroing and calibrating the RLO function, allow at least 10 seconds for any
thermal EMFs to dissipate when you move test leads from one socket to another.
Thermal EMFs have a significant contribution to the error present in the lower ohm
measurements.
7. Disconnect the test leads from each other and connect the DUT green connector (ground)
to the green (PE) port on 532xA and DUT yellow connector to the blue (N) port on 532xA.
See Figure 2.

9. Push on the DUT to set the One Shot mode.
10. Push OPER on the 532xA to set the operate mode, if necessary, and wait for the calibrator
to stabilize.

ISC (Short-Circuit Current)
To v e r i f y :
1. Set all equipment and the DUT to standby mode.
2. Connect the high current test leads from DUT red connector to the Output Terminal + of
the current supply (Keithley 2260B-30-36) and DUT blue connector to the Output
Terminal – of the current supply (Keithley 2260B-30-36). See Figure 4.
Figure 4. ISC (Short-Circuit Current) Connections
3. Turn the rotary switch on the DUT to VOC/ISC.
4. Set the current supply to output >5 V.
A minimum of 5 V is needed to allow the DUT to enter into ISC mode. The maximum voltage
is critical as it determines the amount of overshoot when the ISC circuit is completed. If the
overshoot exceeds 20 A, then no measurement can be made on the DUT.

5. Set the current supply to output the first current test point (see Ta b l e 4 ).
Push the Output button, if necessary to verify the current supply is in operate mode.
6. Momentarily push on the DUT.
Wait for the DUT to complete the measurement. Record the current indication on the DUT
in the test record.
Note
Watch the current supply during this measurement. If it does not go into constant
current mode briefly, then the voltage setting is too low. Increase the voltage of the
current supply and retry step 6until the current supply goes into constant current
mode briefly. Additionally, check a range of about 0.1 V to see if the current indication
on the DUT stays constant. A constant current indication, even with a change of 0.1 V
from the current source, indicates that there is enough voltage output to allow the
current source to enter into constant current mode.
7. Set the current supply to output the next current test point (test points are in Tab l e 4 ).
8. Repeat steps 6through 7for all test points.
9. Set the current supply to standby mode.
