Getting Started
Power ON-OFF
Power the meter by pressing and holding the power button

Press and hold the power button for at least 1.5 seconds to power OFF the meter.
This meter is powered by six (6) 1.5VDC ‘AA’ batteries or by optional AC adaptor. If the meter will not switch ON please check that fresh batteries are installed in the rear battery compartment or, in the case of the AC adaptor, check that the adaptor is connected correctly to the meter and to an AC source.

To turn the display backlight ON or OFF, press and hold the backlight 
button for at least 1.5 seconds. The meter will beep when switching the backlight ON or OFF unless the beeper is disabled.
Vibration Sensor
Connect the vibration pickup to the cable supplied. Make sure it is firmly attached.
Connect the cable to the meter by attaching it to the BNC connector on the top of the meter.
If the surface to be tested is magnetic, attach the magnetic base to the vibration pickup and attach the pickup to a flat surface.
If the surface to be tested is not magnetic, hold the pickup against the surface. Do not hold the cable while making measurements.
Units of Measure
The currently selected unit of measure is shown on the meter’s LCD. To change the unit of measure, press and hold the UNIT button until the desired unit of measure appears and then release the UNIT button. The meter begins scrolling through the available units of measure after the UNIT button has been depressed for at least 1.5 seconds. The saved units will become the default turn-on units.
