Field Adjustments
The unit is powered by a single AA size
lithium battery. In order to install the battery,
remove the back cover and place the battery
on the PC board. The battery polarity is
indicated on the PC board. If the battery is
installed reverse, the unit will not power up.
The back cover is mounted to the front cover
via two mounting holes.

There are 3 LEDs built into the connector.
The °C green LED flashes once every 2
seconds when the output provides 1mV/°C.
The °F green LED flashes once every 2
seconds when the output provides 1mV/°F. If

adjustment when the unit is in mV/°F mode.
R42 provides offset adjustment when the unit
is in mV/°C mode. R32 provides span (gain)
adjustment either in mV/°F or mV/°C mode.
