CMG-40T
Signal meter
The upper section of the HCU contains a simple voltmeter for monitoring
various signals from the instrument.
•
To monitor the low-gain outputs, switch the dial to V, N/S or E/W LOW
VEL according to the component you want to monitor.
•
To monitor the high-gain outputs (on a 40T with that option), switch the
dial to V, N/S or E/W HIGH VEL.
•
To monitor the mass position outputs, switch the dial to V, N/S or E/W
MASS POS. Whilst you are adjusting mass position offsets, you should
also switch the instrument out of broadband mode by switching the
rightmost CENTRING SELECT switch to 1 SEC VEL, or by holding
down the CENTRE button on a breakout box.
•
You can set the range of the meter with the RANGE switch. When
switched to 10 V, the meter ranges from –10 to + 10 V (as marked.)
When switched to 1 V, the range is –1 to +1 V.
