Keypad Test
The keypad consists of six keys located above the rotary switch.
1. To test the keypad, turn the rotary switch to
V and momentarily press each of the
six keys. Each press of an operational key will cause the Meter to beep. No beep
in response to a key press indicates a defective keypad.
2. Reset the Meter by turning it
OFF, and then to any other position.
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 3 for an exploded view of the major assemblies. Also,
the emphasis is placed on disassembly. However, when appropriate, an italicized entry at
the end of each disassembly procedure provides critical hints for reassembly.
