measuring the current shunt voltage (DMM 1). Note that 0.1 V reading represents 1 Amp
if the recommended 100 m shunt is used.
Low Scale Peak Current Measurement Calibration
1. Connect the test equipment to the power source as shown in Figure 6-2.
2. Program the output voltage to 10.0 volts.
3. Use the SELECT key to select the Peak Current Measurement calibration mode. This
mode is indicated by the I PK LED.
4. Use the left control knob to adjust the peak current reading shown on the right hand 7
segment LED until it reads as close as possible to the reference reading shown on the
external DMM (DMM 1) times 1.414. This value is the peak current of a sinewave
current.
Low Scale Power Measurement Calibration
1. Connect the test equipment to the power source as shown in Figure 6-2.
2. Program the output voltage to 10.0 volts.
3. Use the SELECT key to select the Power Measurement calibration mode. This mode is
indicated by the PWR LED.
4. Calculate the power by multiplying the external reference current reading (DMM 1) in
amps with the external reference voltage reading (DMM 2).
5. Use the left control knob to adjust the power measurement reading shown on the right
hand 7 segment LED until it reads as close as possible to the calculated power reading.
Note: The method of adjusting the low scale values for voltage, current and
power insure that the measured value is correct for small values. Under a
no-load condition, however, the measured value may not be 0
