Measurement
Calibration (CAL) mode
This mode serves for electrical calibration of equipment connected to the AC
OUT connectors on the rear panel.
The calibration reference signal available at the AC OUT connectors is an
80 Hz sinusoidal wave signal with a range full-scale value of 1 V (Peak).
Example
When the range setting is 10 m/s
2
, the calibration signal
is 1 V = 10 m/s
2
(Peak).
Calibration procedure
1. At the highest range setting of channel A or channel B, press the
RANGE
key once more to switch from measurement mode to
calibration mode.
