USING THE M/2
The Model M/2 is turned ON by pressing the Power On/Off button on the instrument panel. When powered
On, the M/2 will flash the Blue LEDs through each of the four (4) output voltages. Once the LED’s flash
through once, the LED will indicate the selected output voltage.
A Low Battery condition exists when all four (4) of the Blue LEDs continue to flash. The 9v battery should
be replaced when this indication occurs.
MAIN PANEL AND LED INDICATORS
The main instrument panel includes two (2) buttons and five (5) LED indicators. The RED LED indicates a
holiday signal. This LED will light along with the audible tone indicator of a holiday.
The four (4) output voltage settings each have an associated LED. The LED that is illuminated indicates
the output voltage of the M/2.
ADJUSTMENT OF THE OUTPUT VOLTAGES
Model M/2 Holiday Detector offers four (4) output voltages and sensitivity settings.
9v @ 90 K-ohms
67.5 volts @ 80 K-ohms
67.5 volts @ 90 K-ohms
90 volts @ 400 K-ohms
When the M/2 is powered On, the Blue LED will indicate the selected voltage output. Pressing the Output
Voltage button will change the voltage selection, and a Blue LED will indicate the new output voltage.
Consult with the coating manufacturer, inspector or the standard being referenced for the application to
determine which output voltage is suggested.
CHANGING THE BATTERY
The M/2 is powered by a replaceable 9v battery. To access
the battery, locate the BATTERY ACCESS label on the main
top panel of the instrument. There are two (2) screws near
the handle that need to be removed. Once removed, lift and
rotate the BATTERY ACCESS door toward the front of the
instrument and remove. Replace the BATTERY ACCESS
door by hooking the latch under the mail panel and rotating
back into place. The latch will snap in and the BATTERY ACCESS door will sit flush when properly aligned.
The 9v battery is located inside the battery access area and is attached to a battery terminal connector.
The battery connecter can be removed by firmly grasping the battery with one hand and the connector with
the other and pulling apart. Do not use a screwdriver or any prybar made of a conductive material to
separate the battery from the connector.
When replacing the battery, observe polarity. The 9v battery has two terminals side by side. The smaller
