DPM 340
A very compact low-cost LED module ideally suited for applications where a bright display under all conditions is required. The DPM 340
is fitted with high efficiency, very low current LEDs and is housed in a carrier with integral snap-in bezel. The small size and low cost of the
unit makes it very suitable for high volume OEM applications.
SCALING
Two resistors Ra and Rb may be used in order to
alter the full scale reading (F.S.R.) of the meter - see
table.

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 DISPLAY AREA). The snap-in lugs will now automatically hold the meter firmly in position.

... DP COM Connect to required decimal point (DP1, DP2 or DP3) to illuminate. This pin is not fitted as standard to the DPM 340. Note: A negative supply is generated internally and mirrors the positive supply. For example +5V, then the internally generated V- is -5V. When measuring with the input referenced to the same supply rail as that of the panel meter, then the limitations on the input range are ( ...
