DPM 125
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.
SCALING
Two resistors may be used to alter the full scale reading of
the meter - see table.
Note that the meter will have to be re-calibrated by
adjusting the calibration pot .
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.
