DPM 3
3½ Digit Subminiature LCD Module
The DPM 3 is the largest in our sub-miniature series of meters but still uses the same miniaturisation techniques to produce a very compact
instrument. The snap-in integral bezel makes installation easy. For single rail operation, the DPM 3S features a built in negative rail generator,
enabling the meter to measure a signal referenced to its own power supply 0V.

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
THE LCD). The snap-in lugs will now automatically hold the meter firmly in position.
