the user need only drill a single 5.5mm /
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.
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).
