233 True-rms Remote Display Digital Multimeter Calibration Information Introduction XWWarning To avoid electric shock or injury, do not perform the performance tests or calibration adjustment procedures unless qualified to do so. The information provided in this document is for the use of qualified personnel only.
33 Calibration Information Safety Information A Warning identifies hazardous conditions and actions that could cause bodily harm or death. A Caution identifies conditions and actions that could damage the Meter, the equipment under test, or cause permanent loss of data. XWWarning To prevent possible electrical shock or personal injury, follow these guidelines: • Use this Meter only as specified in this manual or the protection can be compromised. • Do not use the Meter if it is damaged.
True-rms Remote Display Digital Multimeter International Electrical Symbols WCaution To prevent damage to the Meter or to the equipment under test, follow these guidelines: • Disconnect circuit power and discharge all high-voltage capacitors before you do diode tests or measure resistance, continuity, or capacitance. • Use the correct terminals, function, and range for all measurements. • Before a current measurement, do the fuse test.

True-rms Remote Display Digital Multimeter Battery Replacement Battery Replacement XWWarning To prevent incorrect measurements, possible electrical shock, or personal injury, replace the battery when the battery indicator () appears. If the display shows , the Meter will not function until the display module batteries are replaced. If the display shows , the Meter will not function until the Meter-base batteries are replaced.
233 Calibration Information Remove the Display Module To remove the display module (see Figure 2): 1. Push in on the latches on the sides of the display module. 2. Pull the display module off of the top end of the Meter base. The Meter base and display module can be a maximum of 10 Meters (30 feet) from each other before the radio connection is broken. This distance can change if obstacles are between the Meter base and the display module.
True-rms Remote Display Digital Multimeter Fuse Test 2 3 gcc111.eps Figure 3. Display-Module Battery Removal Fuse Test To test the fuse: 1. Set the rotary switch to Ω. 2. Plug a test lead into the v jack and touch the probe to the 10A jack, as shown in Figure 0-4. If the display shows a resistance value in the range of that shown in Figure 0-4, the fuse is good. If the display reads 0L, replace the fuse and test again. If the display shows any other value, have the Meter serviced.
233 Calibration Information Fuse Replacement To replace the fuse: 1. Remove the test leads from the Meter. 2. Remove the display module from the Meter base. See the “Remove the Display Module” section. 3. As shown in Figure 5, remove four screws from the case bottom. 4. Pull the case bottom from the case top. 5. Remove the fuse from its holder and replace it with an 11 A, 1000 V, FAST fuse with a minimum interrupt rating of 17,000 A. Use only Fluke PN 803293.
True-rms Remote Display Digital Multimeter Performance Tests Performance Tests XWWarning 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 its specifications. The recommended calibration interval is 12 months. If the Meter fails any part of the test, calibration adjustment and/or repair is indicated.
233 Calibration Information Testing the Display Push K and turn the rotary switch to the e position. Compare the display with the example in Figure 6. Check all segments for clarity and contrast. erc022f.emf Figure 6. Display Segments Backlight Test To Test the Backlight, press Q and verify that the backlight comes on. Keypad Test To test the keypad, turn the Meter to ACV and push each button separately. Each button push should cause the Meter to beep and activate a display annunciator.
True-rms Remote Display Digital Multimeter Performance Tests 3. Apply the input level for each step listed in Table 3. 4. Compare the reading on the Meter display with the Display Reading in Table 3. 5. If the display reading falls outside of the range shown in Table 3, the Meter requires calibration adjustment or repair. Temperature Tests Connect the K-type thermocouple to the temperature input of the Meter and temperature calibrator.

True-rms Remote Display Digital Multimeter Calibration Adjustment 3. Turn the rotary switch to OFF. Calibration Adjustment Password To start the Calibration Adjustment Procedure, the correct 4-digit password must be entered. The default password is “1234”. The password can be changed or reset to the default as described in following paragraphs. Changing the Password Use the following steps to change the Meter’s password: 1. While pressing K, turn the rotary switch from OFF to Ω function.
233 Calibration Information S103 XBT101 XBT102 erc12f.emf Figure 7. Calibration Password Reset Meter Buttons Used in the Calibration Steps When performing the Calibration Adjustment Procedure, the Meter buttons behave as follows. This may be of help in determining why a calibration step is not accepted and for determining the input value without referring to Table 4. 1. Press and hold K to show the measured value. The measured value is not calibrated so it may not match the input value. This is normal.
True-rms Remote Display Digital Multimeter Calibration Adjustment Note Some adjustment steps require additional wait time after the calibrator settles, as noted in Table 4. 7. After each input value is applied, press g to accept the value and proceed to the next step (C-02 and so forth). Notes After pressing g, wait until the step number advances before changing the calibrator source or turning the Meter’s rotary knob.
