Reassembling the Meter
To reassemble the Meter, logically reverse the previous disassembly procedures. In
the process, make sure to re-establish all electrical connections; specifically, the
elastomeric strip for the LCD, the red and black plastic shields for the input terminals,
and the two spring contacts for the Insulation Test Probe. Also make sure all parts are
correctly aligned and positioned; do not force-fit any of the parts into position.
Required Tools and Equipment
Table 1 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.
