Push Button
= Test Button, turns on internal sensor test signal, at the same time activates
visible laser positioning beam for easy target aiming when the button is pressed.

= Normal Sensitivity Threshold Level Adjustment Potentiometers. When adjust to
maximum sensitivity (7), detect target temperature 400

H
= High Sensitivity Threshold Level Adjustment Potentiometers. When adjust to maximum
sensitivity (7), detect target temperature 250

Adjust sensitivity of the detector within each range, 1 to 7 refers low to high
Toggle Switch
= Sensitivity range selection, N (normal) or H (high), use corresponding
potentiometer for the sensitivity adjustment.

5.2 Automatic Threshold Level Description
Definition-
The HMD-SM includes an Automatic Threshold Level Adjustment. The sensor’s
built in circuit will automatically adjust the signal output when hot metal enters scanning
field to prevent detect signal from saturation. According to different field applications, base
threshold signal level is determined on installation. Follow “Base Threshold Level
Adjustment Procedure”
in this section to setup the right threshold level.
Sensitivity-
Flip sensitivity toggle switch to N (or H), Tune the corresponding threshold level
potentiometer clockwise will increase the sensitivity leveled from 1 to 7 in its range.
