WCaution To avoid damaging the Meter, never apply abrasives, solvents, aromatic hydrocarbons, chlorinated solvents, or methanol- based fluids to the Meter. Periodically wipe the Meter case with Fluke “MeterCleaner ” or a damp cloth and mild detergent.
True-rms Multimeter Basic Maintenance Dirt or moisture in the A or mA µA input terminals can affect readings and can falsely activate the Input Alert feature without the test leads being inserted. Such contamination may be dislodged by turning the Meter over and, with all test leads removed, gently tapping on the case.
87V EX Calibration Manual aom12f.eps Figure 1. Opening the Meter, Battery and Fuse Replacement Reassembling the Meter Case To reassemble the Meter case: 1. Verify that the rotary knob and circuit board switch are in the OFF position, and that the gasket remains secured to the bottom case.
True-rms Multimeter Basic Maintenance Replacing the Battery Replace the Meter’s 9-volt battery with only approved batteries found in Table 2. XWWarning To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator (b) appears.

87V EX Calibration Manual Calibration Adjustment Password WCaution To avoid having to replace the Meter, do not change the calibration password. To start the Calibration Adjustment Procedure, the correct 4-button password must be entered. The password is “1234”. Meter Buttons Used in the Calibration Steps The Meter buttons behave as described in Table 6 when performing the Calibration Adjustment Procedure.

True-rms Multimeter Calibration Adjustment If the Meter rotary knob is not in the correct position, or if the measured value is not within the anticipated range of the input value, the Meter emits a double beep and will not continue to the next step. Some adjustment steps take longer to execute than others (10 to 15 seconds).
