PANEL FITTING
Locate the meter by passing it through the front of the panel cut-out and gently push until the rear of the bezel is flush with the panel (DO NOT PUSH ON
THELCD). Thesnap-inlugswill nowautomaticallyholdthemeter firmlyinposition.
The DPM 2 uses the latest miniaturisation techniques to produce a very compact meter. The snap-in integral bezel makes installation easy. For
single rail use, the DPM 2S features a built in negative rail generator, enabling the meter to measure a signal referenced to its own power supply
0V.
