QM110T is an easy to mount LCD digital panel meter.
To mount the module,
the user need only drill a single 5.5mm / hole in the panel. The module is fitted to the panel by locating its screw threaded stud through the hole, fitting the
washer and tightening the nut provided. The module's connecting wires pass through the hollow stud into the target application, where they can be easily
plugged or soldered into place.
The module can measure ambient temperature via a built-in sensor and outside temperature via an
external sensor (not supplied). The module uses NTC temperature sensors to ensure high accuracy over a wide temperature range.

A rubber seal is included, providing splashproof protection for the unit when fitted to the meter during installation.

SAFETY
As the NTC temperature sensor is a passive device, no voltages should be applied to the input terminals. The user must ensure that the
incorporation of the meter into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for
Measuring, Control and Laboratory Use).

* Using external NTC sensor with 10k @ 25°C and a 25 to 85°C Beta value of 3977, for example:
BC Components 2322-640-73103. The module may require recalibration.
To ensure maximum accuracy, recalibrate periodically. Calibrate the module at top end of
measurement range.
** Do not apply more than 28V, as this may damage the meter.
