Connecting the Probe

2. Plug the BNC connector side of the probe into the BNC connector at the top of the
meter.
3. The probe can be connected to the machinery under test in three ways.
a. Attach the magnetic end of the probe to a ferrous material on the equipment under
test.
b. Hold the probe in place against the equipment under test manually.
c. Unscrew the magnet from the probe end and use the threaded mount to connect to
a screw, bolt, or stud on the equipment under test.
Powering the meter
1. Press the POWER button to turn the meter ON or OFF.
2. The meter is equipped with an automatic power off utility that conserves battery life. If
the meter is left inactive for 10 minutes it will automatically turn off. The automatic
power off utility is disabled in the RECORD mode (see below).
Using the Selector switches
1. RMS/PEAK Switch: Select the RMS setting for RMS measurements. Select the PEAK
mode for peak measurements. Peak measurements are derived from the RMS reading
multiplied by 1.414.
2. ACC/VEL Switch: Use this switch to select ACCELERATION measurements or
VELOCITY measurements. Note that VELOCITY measurements are the most widely
used measurements in industrial applications.
3. METRIC/ENGLISH Switch: Use this switch to select the desired units’ convention.
