6.3.3 Measurement Calibration - Full Scale
Note:
Measurement calibration can be done at any output frequency setting
as only one set of calibration coefficients is used for measurement
calibration. However, for best results, calibrate the measurements at
the frequency which is used in most applications, e.g. 50 Hz, 60 Hz
(except model 2001RP-AV) or 400 Hz.
Refer to Table 6-1 for correct load resistors based on model number.
1. Connect the test equipment to the power source as shown in Figure 6-1. Do not connect
any load during this step. Voltage calibration must be done under no load conditions.
Full Scale Voltage Measurement Calibration
2. Select the High Voltage Range and program the output voltage to 240.0 volts AC or the
maximum voltage available if less than 240 Volts.
3. Put the 2001RP in CAL mode by pressing the recessed CAL button.
4. Use the SELECT key to select the Voltage Measurement calibration mode. This mode is
indicated by the FREQ LED.
5. Use the left control knob to adjust the voltage reading shown on the right hand LCD until
it reads as close as possible to the reference reading as displayed on the external DMM.
1. Connect the test equipment to the power source as shown in Figure 6-2.
Full Scale Current Measurement Calibration
2. Apply the 11.3
Ω resistive load to the output terminals. Make sure the external DMM
used for voltage measurement is across the sense terminals.
3. Program the output voltage to a value that produces between 3 and 3.9 amps. Do not
load the output for more than 3.9 amps.
4. Use the SELECT key to select the Current Measurement calibration mode. This mode is
indicated by the I RMS LED.
5. Use the left control knob to adjust the current reading shown on the right hand LCD until
it reads as close as possible to the reference reading indicated by the DMM measuring
the current shunt voltage (DMM 1). Note that .39 V reading represents 3.9 Amps if the
recommended 100 m
Ω shunt is used.
1. Connect the test equipment to the power source as shown in Figure 6-2.
Full Scale Peak Current Measurement Calibration
2. Select the low voltage range and program the output voltage to a value that produces
about 13 Amps rms.
3. Use the SELECT key to select the Peak Current Measurement calibration mode. This
mode is indicated by the I PK LED.
