This overload indicator is only likely to come on in two situations:

Briefly at startup. This is not a cause for concern.

When the load impedance is too low (< 50 Ω). In this case, turn off the
instrument and connect the proper load.
3. IN Connectors. The input signal is applied to this connector (there are two
connectors on -D units). The input impedance is approximately 1 kΩ. The input must
not exceed ±2V.
4. GAIN Dial. This ten-turn dial is used to vary the amplifier gain b1 and +15.
(There are two separate dials on -D units.) Units with the -INV option will also have
an INVERT / NON-INVERT switch, which changes the polarity (- or +) of the gain.
5. OUT Connector. This BNC connector provides the main output signal (there are two
connectors on -D units). The output is an amplified version of the input on (3). The
gain (V
OUT
/V
IN
) is controlled by (4).
6. OFFSET Controls. (Optional: -OS option only.) This dial varies the DC offset on the
output from 0 to ±15V. The ON/OFF switch below the dial enables and disables this
function. (-D units will have two sets of offset controls).
