WARNIN
DO NOT connect connection cable to the 8947 CHARGE UNIT when
connected to measuring unit to avoid risk of electric shock.
BNC terminal and miniature connecter terminal of each channel share
same GND. Do not connect both at once.
During measuring with measurement mode set to PREAMP or when
level monitor function is in use, electric current (2 mA, +15 V) output is
active. In order to avoid risk of electric shock and damage to testing
device, examine channel mode for connecting sensor and probe to BNC
terminal and either cancel PREAMP or shut down power.
Voltage measurement and internal acceleration pick up sensor share
same terminal. Make sure to check measurement mode before
measuring.
Before using internal acceleration pickup sensor, verify that sensor
ratingis compatible with 8947 CHARGE UNIT rated output (2 mA, +15 V).
Use of Non compatible sensor may cause damage to sensor.

.9 Making the Settings of the 8947 CHARGE UNIT
8947 CHARGE UNIT can measure voltage or acceleration in each channel.
(One type of measurement per channel)
Charge:
Measures with electrical charge output piezoelectric
acceleration pickup sensor.
Preamp:
Measures with preamplifier internal acceleration
pickup sensor.
Voltage:
Measures voltage waveform.
System reset defaults to Electrical Charge
setting.
The settings of the waveform display color, waveform display graph type,
magnification/compression ratio along the voltage axis, zero position, zero
adjustment, baseline offset and low-pass filter are the same as in the 8936
ANALOG UNIT.
For the settings, see Section 7.3.
