A Warning identifies hazardous conditions and procedures that are dangerous to the user. A Caution identifies conditions and procedures that can cause damage to the Product or the equipment under test.

Static Awareness

Semiconductors and integrated circuits can be damaged by electrostatic discharge during handling. This notice explains how to minimize damage to these components.

1. Understand the problem.
2. Learn the guidelines for proper handling.
3. Use the proper procedures, packaging, and bench techniques.

Follow these practices to minimize damage to static sensitive parts.

Warning

To prevent electric shock or personal injury. De-energize the product and all active circuits before opening a product enclosure, touching or handling any PCBs or components.

Illustration of a hand holding an integrated circuit chip (no text or symbols)

• Minimize handling.
• Handle static-sensitive parts by non-conductive edges.
• Do not slide static-sensitive components over any surface.
• When removing plug-in assemblies, handle only by non-conductive edges.
• Never touch open-edge connectors except at a static-free work station.

Illustration of an integrated circuit chip and its external I-beam (no text or symbols)

• Keep parts in the original containers until ready for use.
• Use static shielding containers for handling and transport.
• Avoid plastic, vinyl, and polystyrene foam in the work area.

Maintenance

Caution

To prevent possible damage to the Product or to equipment under test, do not use abrasive cleansers.

Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings.

Battery Replacement

Warning

To prevent possible explosion, fire, or personal injury, replace the batteries when the low battery indicator (+) shows to prevent incorrect measurements.

Caution

To prevent possible damage to the Product or to equipment under test:

• Remove batteries to prevent battery leakage and damage to the Product if it is not used for an extended period.
• Be sure that the battery polarity is correct to prevent battery leakage.

Figure 1 shows how to replace the battery.
Figure 1. Battery Replacement

To replace the batteries:

1. Turn off the Product.
2. Turn over the Product to access the battery compartment door screw.
3. Use a flat-head screwdriver to loosen the battery compartment door screw and lift off the battery compartment door.
4. Replace the two AAA batteries. Make sure to use the correct polarity when you put the batteries into the battery compartment door.
5. Reattach the battery compartment door.
6. Tighten the battery compartment door screw.

Jaw Maintenance

If the Product does not work properly:

1. Inspect the jaw mating surface for cleanliness. If any foreign material (including rust) is present, the jaw will not close properly and measurement errors will result.

Calibrator 4.5-digit resolution	on 5522A or equivalent
Wired Coil	50 turns	5500A/Coil or equivalent

Performance Tests

Warning

To prevent possible electrical shock, fire, or personal injury, do not go through the performance test procedures unless the Product is fully assembled.

The performance tests verify the full operation of the Product and measure the accuracy of each function against the Product specifications. If the Product fails a part of the test, calibration adjustment and/or repair is necessary. See Calibration Adjustment.

Before you do the performance tests:

1. Make sure that you have the necessary equipment. See Table 2.
2. Make sure the Product batteries are charged or replace them if necessary. See Battery Replacement.
3. Warm up the Calibrator as necessary. Refer to its specifications.
4. Let the temperature of the DUT (device under test) become stable to room temperature.

Display and Firmware Version

To verify that all segments of the display function:

1. With the Product off, push and hold HOLD.
2. Turn the Product on.
3. All display segments are shown. See Figure 2.

If segments of the display are missing, repair is necessary. See Contact Fluke.

Figure 2. Display Segments

When HOLD is released, the firmware current version shows, for example, r013. F301 designates the model number.

Backlight

To verify that the backlight functions:

1. With the Product on, long press ☐. The backlight comes on.
2. Long press □ again to turn off the backlight.
3. If the backlight does not function correctly, repair is necessary. See Contact Fluke.

Button Test

To verify that the buttons function, turn on the Product and push each button separately. Each button push causes the Product to beep. When you push HOLD, HOLD shows on the display. If the buttons do nothing, repair is necessary. See Contact Fluke

Current

To do the current test:

1. Connect the Calibrator Amp output and ground to the 50-Turn Coil. See Figure 3 for test connections.
2. Turn the rotary switch to .
3. Apply the input level for each step shown in Table 3.
4. Compare the indication on the Product display with the DUT reading limits in Table 3. If the display indication is outside of the range shown in Table 3, calibration adjustment or repair of the Product is necessary. See Calibration Adjustment.

Calibration Adjustment

The Product features closed-case calibration adjustment and uses known reference sources. 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.

For information about damage by electrostatic discharge, see Static Awareness.

To do the calibration adjustment:

1. Remove the Product battery door. See Battery Replacement.
2. Apply 3.0 V across the battery contacts on the PCA. Note the polarity in Figure 5.
3. Turn the rotary switch to the function to OFF.

4. Remove the calibration seal.

5. While shorting across the CAL keypad on the PCA, turn the rotary switch to the function to adjust. See Figure 5.

6. When CAL shows on the display, remove the short.

This puts the Product into calibration mode.

1. When the real value shows on the display, apply the correct input signals from Table 5 to the Product. For each function, the calibration step shown on the display will advance.

2. After each step, push on the front to confirm the calibration step, store the value, and go to the next step.

3. Set the Calibrator to Standby after you complete adjustment of each function.

Note

If any calibration point is missing, Err is shown on the display.

After you push ☐, wait until the calibration step number advances before you change the calibrator source. Some adjustment steps can take several seconds to execute before the Product goes to the next step.

1. When calibration adjustment is complete, remove the 3.0 V supply.

The Product exits the calibration mode automatically.

1. Replace the batteries and battery door.
