4. OPERATION
4.1. VOLTAGE MEASUREMENTS
4.1.1. Input Voltages up to 300 Volts RMS
1. Calibrate the 2010 as described in section 3.2.1.
2. Set the controls as follows:
GAIN CONTROL
INPUT SECTION ATTENUATOR
OUTPUT SECTION ATTENUATOR
EFFECTIVE AVERAGING TIME
READ OUT SELECTOR
FREQUENCY RESPONSE
INPUT push-button
"Cal."
"300 V"
"x
1"
"Fast" or as appropriate
for analysis
As appropriate to scale used
and output required
"Linear"
As appropriate
3. Feed the unknown voltage to the input used, and adjust the INPUT
SECTION ATTENUATOR until a suitable deflection is obtained. If
the deflection is insufficient, even when the INPUT SECTION
ATTENUATOR is in its "10 mV" position, then adjust the OUTPUT
SECTION ATTENUATOR.
4.1.2. Input Voltages up to 700 Volts Peak
Use can be made of the GAIN CONTROL to accommodate input volt-
ages of up to 700 Volts peak. However the 2010 must be calibrated to give
exactly 10 dB attenuation. Procedure is as follows:
32
1. Repeat the calibration procedure, as described in section 3.2.1.
2. With the meter scale pointer set on the red mark (50 mV) set the
INPUT SECTION ATTENUATOR to 30 mV causing the needle to
deflect off scale.
