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.
