6.3.2 Measurement Calibration - Low 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.
Low Scale Voltage Measurement Calibration
1. Connect the test equipment to the power source as shown in Figure 6-2. Do not
connect any load during this step. Voltage calibration must be done under no load
conditions.
2. Select the Low Voltage Range and program the output voltage to 10 volt AC.
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.

Low Scale Current Measurement Calibration
1. Connect the test equipment to the power source as shown in Figure 6-1.
2. Do not apply a load to the output terminals. Make sure the external DMM used for
voltage measurement is across the same terminals.
