Insulation Multimeters Basic Maintenance Basic Maintenance This basic maintenance section of the manual contains tests and procedures that require no equipment other than the Meter and some consumables such as fuses and batteries. Also, internal access is limited to the battery and fuse compartment. h Static Awareness h X Semiconductors and integrated circuits can be damaged by electrostatic discharge during handling. This notice explains how to minimize damage to these components. 1.
1587 FC/1587/1577 Calibration Manual Cleaning When cleaning is necessary, wipe the Meter with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture on the terminals can affect readings. Testing the Batteries Under Load XWWarning To avoid electrical shock or personal injury, replace the batteries as soon as the battery indicator () appears. A weak battery can cause false readings. Before testing the batteries, turn the Meter to B.
Insulation Multimeters Basic Maintenance Testing the Fuse XWWarning To avoid electrical shock or injury, remove the test leads and any input signals from the Meter before replacing the fuse. Test the fuse as described below and illustrated in Figure 1. If the fuse is defective, see Replacing the Batteries and/or Fuse later in this manual. 1. Insert a test probe in the J input terminal. 2. Turn the rotary switch to N and verify the Meter is in Auto Range. 3. Insert the probe in the mA input terminal.
1587 FC/1587/1577 Calibration Manual Replacing the Batteries and/or Fuse Use the following procedure and Figure 2 to replace the batteries and/or the fuse: XWWarning To avoid electrical shock, personal injury, or damage to the Meter observe the following warnings: • Replace the batteries as soon as the battery indicator () appears. A weak battery can cause false reading. • Use ONLY fuses with the amperage, interrupt, voltage, and speed ratings specified.
Insulation Multimeters Basic Maintenance Testing the Display The display is an LCD comprised of a series of characters and segments for providing the user with a variety of information. To test the LCD and all of its segments proceed as follows: 1. Set the rotary switch to OFF. 2. Depress and turn the function switch to B. 3. While continuing to depress , verify that the lit display segments match those shown in Figure 3. bav01f.eps Figure 3.
1587 FC/1587/1577 Calibration Manual Disassembling and Reassembling the Meter This section of the manual provides instructions for disassembling and reassembling the Meter. The instructions are limited to major replaceable assemblies and do not include component-level detail. See Figure 4 for an exploded view of the major assemblies. Also, the emphasis is placed on disassembly. When necessary, the procedure includes critical hints for reassembly.
Insulation Multimeters Disassembling and Reassembling the Meter When installing the boot, position the bottom of the Meter in the bottom of the boot, and press the top of the instrument firmly into of the boot. Removing the Battery Door XWWarning To avoid the risk of electrical shock, turn the rotary switch to OFF, and remove the test leads from the front-panel terminals before removing the battery cover. With the boot removed, the next step in disassembling the Meter is to remove the battery door.
1587 FC/1587/1577 Calibration Manual connections by carefully pulling each of the springs back and away from the terminals. See Figure 5. 3. With one hand over the PCA, roll the top case over (face up) and lift it away from the PCA. Note Three red and one black plastic shields are used to isolate the user from the input terminals. With the PCA removed, these shields are loose and can fall away from the PCA. 4. Remove and set aside all four shields for use during reassembly.
Insulation Multimeters Disassembling and Reassembling the Meter Removing the LCD With the PCA removed, the final step in disassembling the Meter is to remove the LCD assembly from the PCA. Refer to Figure 6 and use the following procedure to remove the LCD assembly: 1. Remove the two screws from the display end of the PCA. 2. Hold the PCA face down with the fuse-end of the PCA toward you. Locate the screw-hole near the center of the assembly.
1587 FC/1587/1577 Calibration Manual panel. After the LCD assembly is in position, lock it in place by pressing (below the display) the bezel against the PCA; listen for the tab on the bezel to snap (lock) into position on the PCA. 8. Secure the PCA to the LCD assembly by installing the two screws that attach the PCA to the bezel. These screws also ensure contact between the glass LCD display, the elastomeric strip, and the PCA.
Insulation Multimeters Required Tools and Equipment Required Tools and Equipment Table 2 lists the require equipment for performing the Performance Test and Calibration adjustments. If a recommended model is not available, use a substitute with equivalent or better specifications. Table 2.

1587 FC/1587/1577 Calibration Manual Meter Keys Used in the Calibration Steps The Meter keys behave as follows when performing the Calibration Adjustment Procedure. This may be of help determining why a calibration step is not accepted and for determining the input value without referring to Table 6. H Press and hold to show the measured value. The measurement value is not calibrated so it may not match the input value. This is normal. Press and hold to display the required input amplitude.
Insulation Multimeters Calibration Adjustment Procedure Note Set the calibrator to Standby prior to changing the function switch position and/or after completing adjustment of each function. If the calibration adjustment procedure is not completed correctly, the UUT will not operate correctly. Table 6.
