NOTE
Internal gain: Gain from the input to the output of the DPM-900/950 series.
Capable of setting the internal gain within ×200 to ×20000.
In addition, when the internal gain is large, it means high sensitivity and when it is small, low
sensitivity.

POWER ON/OFF
Press the POWER switch for turned ON and press again for turned OFF.
Lights up when using the internal oscillator output for the excitation
voltage of the DPM-900/950 series as the carrier.
Indicates an output voltage by the length of the bar.
One LED segment corresponds to 2 V.
When the internal gain is fine adjusted to lower than ×200, 0 (orange LED)
flickers. For details, read "4-6-5 Sensitivity Fine Adjustment."
Displays the cutoff frequency of the L.P.F.
Indicates the output voltage of the OUTPUT A and B in general.
If the output voltage at the OUTPUT A or OUTPUT B exceeds ±11V,
numbers or characters on the monitor flicker.
In addition, indicates the physical quantity in TEDS mode and error content
in error mode.
When outputting 0.5 Vrms excitation voltage, the BV 0.5 V lamp lights up
and when outputting 2 Vrms excitation voltage, the BV 0.5 V lamp lights
out.
Lights up when displaying voltage on the monitor. Lights out only in the
TEDS mode.
Lights up when the H.P.F. switch is set to valid. When invalid, the H.P.F.
lights out.
Lights up after setting the internal gain correctly.
After setting the internal gain, if the set value of the VOLTAGE OUT
switch is changed, the VOLTAGE OUT lamp flickers.
Lights up after setting the internal gain correctly.
After setting the internal gain, if the set value of the CAL switch is
changed, the CAL lamp flickers.
Lights out when in TEDS mode and ACTL LOAD mode.
