Getting Started
Power ON-OFF
- Power the meter by pressing and holding the power button for 3 seconds.
- Press and hold the power button for at least 3 seconds to power OFF the meter.
- This meter is powered by eight (8) 1.5V ‘AA’ batteries or by 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.
Display Backlight
To turn the display backlight ON or OFF, press and hold the backlight button for 3 seconds. The meter will beep when switching the backlight ON or OFF unless the beeper is disabled.
Vibration Sensor
- Connect a vibration pickup to the cable supplied. Make sure it is firmly attached.
- Connect the cable to the meter by attaching it to a connector at 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 ACC/VEL/DISP (up arrow) button until the desired unit of measure appears and then release the button. The meter begins scrolling through the available units of measure after the button has been depressed for 3 seconds. The saved units will become the default power-on unit of measure.
