4-20 mA Clamp Performance Test
Do the performance test periodically and after calibration.
The performance test requires a calibrator with a current loop from the AUX terminal to the LO terminal. See Table 2.
To short the two terminals, use a conductor with 2 banana jacks at both ends. To ensure the clamp closes properly,
the diameter of the conductor should be no more than 4 mm. The Meter must be factory-calibrated to calibrate the
clamp.
To make the calibration adjustment:
1. Make sure you have the necessary equipment, see Table 2.
2. Allow the Meter and the 4-20 mA clamp to stabilize to room temperature.
3. Connect the 4-20 mA clamp to a calibrated Meter.
4. Use 1 loop insulated copper wire to short circuit the calibrator current output AUX and LO terminals, see
Figure 8.
5. Clamp the 4-20 mA current clamp around the insulated copper wire. Current flow should be in the direction of the
arrow on the current clamp.

2000 mA Clamp Balance Test
Do the balance test after calibration. The balance test evaluates the clamp measurement error when the clamp is in
different positions. If any position fails the balance test, a balance adjustment is required. See 2000 mA Clamp
Calibration Adjustment.
To do the balance test:
1. Make sure you have the required equipment. See Table 2.
2. Connect the equipment. See Figure 6.
3. Power on all the equipment.
4. On the 5522A, set the 9.0 A dc output to the 50-turn 1 kA coil and place the clamp on it.
5. Push  until b-UP shows, then move the jaw and locate the coil center in the top area of the jaw. Hold for
5 seconds.
6. Push  until b-do shows, then move the jaw and locate the coil center in the bottom area of the jaw. Hold for
5 seconds.
7. Record the reading.
The reading difference between the top and bottom position must be below 1.0 A (10 digits.)
Calibration
Use the calibration procedures to adjust the Product so that the values shown on the Meter correspond as closely as
possible with the actual measured values. The Product measures the applied reference source, calculates correction
factors, and stores the correction factors in nonvolatile memory.
Should the Product fail any of the performance tests, do the calibration adjustment procedure.
Note
The first calibration of the Product is available from the Fluke factory only.
Meter Calibration Adjustment
Before you can adjust the Meter calibration, you must enter your password in the Maintenance Mode.
1. Follow the instructions to enter Maintenance mode (see Start Maintenance Mode) and then:
a. Push  until CAL shows on the display.
b. Follow the steps in Enter the Password until C-01 shows on the display.
2. For each value in Table 6:
a. Apply the Calibrator Output value to the Meter.
b. Push to confirm the calibration step.
If the input signal does not satisfy the calibration requirement, the Meter shows Err. If the signal is not stable, you
must push several times to confirm the calibration.
After you confirm the calibration, the Meter goes to the subsequent calibration step. When the last calibration
point is recorded, End shows on the display. See Figure 7.
Note
After you push wait for the calibration step number to advance before you change
the calibrator source. Some adjustment steps can take several seconds to complete
before the Meter goes to the subsequent step. Set the Calibrator to Standby after you
complete adjustment of each function.
Note
While the calibration adjustment points are shown in Table 6, the Meter shows the
necessary inputs. For each step, push to see the necessary dc reference signal
amplitude. Use the connections shown in Figure 8.

4-20 mA Clamp Calibration Adjustment
The calibration adjustment requires a calibrator with a current loop from the AUX terminal to the LO terminal. See
Table 2. To short the two terminals, use a conductor with 2 banana jacks at both ends. To ensure the clamp closes
properly, the diameter of the conductor should be 4 mm. The Meter must be factory-calibrated to calibrate the
clamp.
During the calibration adjustment the temperature must be controlled to 23 °C ±5 °C.
To make the calibration adjustment:
1. Allow the Meter and the 4-20 mA clamp to stabilize to room temperature.
2. Connect the 4-20 mA clamp to a calibrated Meter.
3. Use 1 loop insulated copper wire to short circuit the calibrator current output AUX and LO terminals, see
Figure 8.
4. Clamp the 4-20 mA current clamp around the insulated copper wire. Current flow should be in the direction of the
arrow on the current clamp.
5. Follow the instructions to enter Maintenance mode (see Start Maintenance Mode) and then:
a. Wait 20 seconds for the Meter to warm up.
b. Push  until JC shows on the display.
c. Follow the steps in Enter the Password until PoS shows on the display.
6. For each value in Table 7:
a. Apply the Calibrator Output value to the Meter.
b. Wait 4 seconds for the signal to stabilize.
c. Push to confirm the calibration step.
7. When you have completed the calibration, push once to enter normal measurement.
