Read First: Safety Information
To ensure safe operation and service of the meter, follow these instructions:
Avoid working alone so assistance can be rendered.
Never use the meter on a circuit with voltages higher than
600 V or a frequency higher than 400 Hz fundamental. The meter may be damaged.
Never measure current while the test leads are inserted into
the input jacks.
Do not use the meter or test leads if they look damag ed .
Use extreme caution when working around bare conduc t ors
or bus bars. Contact with the conductor could result in electric shock.
Read the instruction card before use and follow all safety
instructions.
Use the meter only as specified in the instruction card;
otherwise, the meter’s safety features may not protect you.
Use caution when working with voltages above 60 V dc or
30 V ac. Such voltages pose a shock hazard.

Safety Information
WWarnings and Precautions
To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or the equipment under test, adhere to the following practices:
Avoid working alone so assistance can be rendered.
Never use the Meter on a circuit with voltages higher than 600 V or a frequency
higher than 400 Hz fundamental. The meter may be damaged. Do not use the Meter or test leads if they look damaged.
Use extreme caution when working around bare conductors or bus bars. Contact
with the conductor could result in electric shock. Read the instruction card and safety sheet before use and follow all safety instructions.
Use the Meter only as specified in the instruction card; otherwise, the Meter’s safety
features may be impaired. Use caution when working with voltages above 60 V dc or 30 V ac. Such voltages
pose a shock hazard. Before using the Meter, inspect the case. Do not use the Meter if it is damaged. Look for
cracks or missing plastic. Pay particular attention to the insulation around the connectors.
Verify the Meter’s operation by measuring a known voltage. Do not use the Meter if it
operates abnormally. Protection may be impaired. When in doubt, have the Meter serviced. Do not apply more than the rated current or voltage, as marked on the Meter.
Use the proper terminals, function, and range for your measurements.
Do not operate the Meter with the case (or part of the case) removed.
When servicing the Meter, use only specified replacement parts.

Performance Tests
WWarning
To avoid electric shock, do not perform the performance test procedures unless the Meter is fully assembled.
The following performance tests verify the complete operation of the Meter and check the accuracy of
each meter function against the Meter’s specifications. If the Meter fails any part of the test, calibration adjustment and/or repair is indicated.
In the performance tests, the Meter is referred to as the unit under test (UUT).

Preparing for the Performance Test
WWarning
To avoid possible electric shock or personal injury:
Do not perform the following procedures unless qualified to do so. Some
procedures involve the use of high voltages. Before handling the test connections and in between tests, make sure the
calibrator is in standby mode (STBY).
To prepare for the performance test:
1. Make sure that you have the required equipment, see Table 1.
2. Warm up the calibrator as required by its specifications.
3. Allow the temperature of the UUT to stabilize at room temperature ( 23 °C ± 5 °C [73 °F ± 9 °F] ).

Performance Tests
Performance Test Procedure
To test each of the Meter’s functions and operating ranges, do the following:
1. Connect the source to the Meter’s V and COM input jacks.
2. Referring to Table 2 for the 321 and Table 3 for the 322, put the Meter in the desired function and
range for each test.
3. Apply the indicated output from the 5520A Calibrator.
4. When using the amp function on the 5520A, make sure LCOMP on the 5520A is ON.
5. The reading on the Meter display should be within the low and high limits shown in the table.
6. Repeat steps 1-4 for each function and range in Table 2 or Table 3. If the Meter fails to perform within the low-high range indicated for each test in Table 2 or Table 3, the
Meter needs to be calibrated and adjusted, or requires some repair.

321 Calibration Adjustment
Use the following steps to adjust the calibration of the 321 (refer to Figure 4):
1. Remove the screws on the bottom of the Meter.
2. Lift off the top case.
3. Apply 600.0 V 50 Hz from the 5520A.
4. Adjust VR1 until display reads within 1.0 V.
5. Apply 4 A 50 Hz from the 5520A to the 50-turn coil. The 50-turn coil will make the meter read 200.0
A 50 Hz .
6. Adjust VR2 until the display reads within 0.5 A. A mirror will need to be used because the calibration
point cannot be seen from the top side of the meter.
7. Replace the top case.
8. Replace the case screws.
9. Verify the calibration by going through the performance test procedures.

Use the following steps to adjust the calibration of the meter (refer to Figure 5):
1. Turn the meter to DC V.
2. Remove the screws on the bottom of the Meter.
3. Lift off the top case.
4. Apply 300.0 V DC from the 5520A to the Meter..
5. Adjust VR1 until the UUT (Unit Under Test) display reads within 0.1 V.
6. Change the meter to the V AC function.
7. Apply 300 V @ 60 Hz.
8. Adjust VR2 until the UUT display reads within 0.1. V.
9. Change to the A AC function.
10. Apply 6 A 60 Hz to the 50-turn coil. The 50-turn coil will cause the Meter read this as 300.0 A 60Hz.
11. Adjust VR3 until this difference between steps 8 and 11 is within 0.1 A. A mirror will need to be used
because the calibration point cannot be seen from the top side of the meter.
12. Replace top case.
13. Verify the calibration by going through the Performance Test procedures.
