Turn on the M3 Digital LCR meter and allow it to warm up for at least 15 minutes to stabilize prior to calibration.
For a detailed explanation of the Calibration and Diagnostics options, see DIAGNOSTICS AND CALIBRATION SCREENS starting on page 19.
To begin calibration, connect the test cable to the DIN socket on the LCR meter. Short the HD and HS clips together using a short piece of wire. Short the LD and LS clips together using another short piece of wire. Turn the LCR meter off.
á Hold down the Model key and apply power to the LCR meter. Release the Model key when the DIAG/CAL screen appears.
á Press the key under CAL (n/Vs/M).
á Press the key under PARAM (L/C/R/Z)
á Press the key under NEXT (L/C/R/Z) until the display shows Mains Frq: 60 Hz on the first line and
NEXT 50HZ 60Hz on the second line. Press the key under 60Hz (Freq).
á Press the key under NEXT. If you are NOT going to adjust the default values for the calibration resistors, proceed to the next step. If you want to change the default resistors values, first review the Calibration Mode (page 21), and continue as follows:
Press the NEXT key. The display will show the calibration resistor value of RCAL1, which is 10.0000 ohms. Pressing the NEXT key will step through the value of all six resistors. To edit the value of any of the calibration resistor values more precisely, press the key under EDIT when the appropriate resistor is shown. A cursor will appear under the first digit. Pressing the key under CHANGE will increment this digit. When the correct number is displayed, pressing the key under NEXT will step to the next digit. Continue to adjust the numbers until the value of your calibration resistor is displayed.
