description
The meter provides two types of measurements
—
overall acceleration and overall velocity. In the velocity mode,
the meter measures in the frequency range of 10 Hz to 1 kHz, and complies with ISO2954 standard. It measures
overall RMS velocity to a maximum of two inches per second. In acceleration mode, the meter measures in the
frequency range of 50 Hz to 50 kHz. The maximum overall RMS acceleration reading is 20 g
’
s. To toggle
between acceleration and velocity measurements, use the rocker switch labeled
“
ACC/VEL .
”
To turn the unit on,
move the rocker switch labeled
“
0/I/Bias
”
to the
“
I
”
position. The
“
0
”
position shuts the unit off, while the bias is a
momentary toggle for monitoring the bias voltage of the sensor.
The meter provides three input connectors that are located at the top of the unit. The input for the sensor (labeled
SENSOR) is a standard BNC Jack. The headphones can be connected through the 1/8 inch stereo jack (labeled
with the appropriate symbol), and the input for the recharger (labeled CHARGE) is a 2.5 mm plug.
The unit is powered by a 9-volt alkaline battery which is housed in the battery compartment located at the bottom
of the meter. To remove this cover, use a small standard screwdriver, pry the cover up, and the push it up
towards the top of the meter. Since the meter is supplied with alkaline batteries, DO NOT ATTEMPT TO
RECHARGE ALKALINE BATTERIES. IT MAY CAUSE A POTENTIAL FIRE AND/OR EXPLOSION.
The unit has a low battery indicator on the front panel LCD display. The indicator will light when the battery
voltage is approximately 7.5 volts. Please replace the battery or recharge the rechargeable battery if supplied.
If the optional recharger was purchased, plug-in the recharger in the appropriate connector located on the top of
the meter. Turn unit off, and plug the charger into an electrical outlet. Recharge the battery for approximately 12
hours.
