DPM 125

3? Digit LCD Module

This compact LCD DPM is ideally suited for low or high volume applications. It features an exceptionally large display in a miniature

package. The meter will plug directly into a SIL socket or can be panel mounted using the snap in bezel provided. The low profile bezel

incorporates a flat reverse printed window giving a superb appearance that cannot be damaged or rubbed of by contact.

PANEL FITTING

Fit the bezel to the front of the panel and then locate the meter into the bezel from behind. Alternatively the meter and bezel may be assembled

before fitting into the front of the panel but care must be taken not to use excessive force. Finally fit the window into the front of the bezel.
