not required under most indoor operating environments. However,
units operating in environments subject to vibration and/or extreme
temperature variations should have their accuracy verifi ed on a yearly
basis. If recalibration is necessary, it should only be performed by
qualifi ed technical personnel. Calibration is performed with potentially
lethal voltages applied to the DMU-30ACV and its associated wiring.
A plastic, fully-insulated adjusting tool must be used to access the
recessed potentiometers located on the back of the unit (see Mechani-
cal Specifi cations). Contact Murata / DATEL if additional information
is required regarding calibration, setup, or any other technical issue
pertaining to DMU-30ACV ac voltmeters.
the DMU-30ACV’s minimum LED display brightness to suit their indoor
viewing requirements by adjusting the ¾-turn, rear-mounted intensity
adjustment potentiometer. Please note, this potentiometer will have
minimal impact on display brightness in high ambient light environ-
ments.
The intensity adjustment potentiometer is factory preset to its mid-
point position. As viewed from the rear of the meter, and with the
model number label facing up, turning the potentiometer clockwise
increases the LED display’s intensity. See the Mechanical Specifi ca-
tions section for potentiometer locations.
(i.e., maximum display brightness) is not required, DMU-30ACV meters
will meet their specifi ed accuracy with ac supply voltages (TB1) well
below 85Vac. While performance is not guaranteed, DMU-30ACV
voltmeters’ remain easily readable and accurate with ac supplies as
low as 20Vac in most indoor environments.
Please note, when operated indoors in a 2-wire mode (i.e., TB1 and
TB2 are connected to the same ac voltage), DMU-30ACV series’ input
current will increase as the input supply is decreased. At 20Vac, the
input supply current will be approximately 30mA.
