As an example, assume that the 10 ohm calibration resistor measures 9.995 ohms using an ACCURATE
ohmmeter. To enter this value, select EDIT for the 10.0000 ohms resistor. The cursor will appear
below the first digit – under the number ‘1’. Press the key under change until this value goes to a blank
position. Press the key under NEXT. The cursor will now be under the second digit – the number ‘0’.
Press the CHANGE key until the number ‘9’ is in this position. Press the NEXT key and the cursor will
move to the digit to the right of the decimal point. Press CHANGE until the ‘9’ appears in this position.
Press the NEXT key and the cursor will move to the right under the next digit – the number ‘0’. Press
the CHANGE key until the number ‘9’ is displayed. Repeat these steps until 9.995 ohms is displayed.
To save this value, press the key under OK. This value will be stored and the display will step to the
next calibration resistor. When you have entered all of the values you want to change, press the NEXT
key until SAVE PARAMETERS is displayed. Press the key under SAVE (n/Vs/M). Continue to the
next step.
· Press the key under CAL (n/Vs/M). The instrument will display STP1: OPEN CAL on the first line
with a left arrow arrow, right arrow, and OK displayed on the second line. Short the HD and HS clips
together and short the LD and LS clips together. Position the two pair of clips the same distance apart
as they will be when connected to the precision calibration resistors. It is recommended that the test
cable not be moved during the entire calibration process. Do not allow the two sets of clips to short
together. This step calibrates the LCR meter for an OPEN state. Press the key under OK (Freq). The
calibration routine will calibrate the OPEN state for each of the 10 test frequencies. There will be a
progress indicator bar displayed on the second line of the display. As each frequency is successfully
calibrated, the instrument will step to the next frequency. If the calibration process fails at any
frequency, the progress bar will stop and !FAIL! will be displayed on the second line. There will also
be an audible alert – long tone. The calibration process will stop and the instrument will return to the
starting screen for the failed step. Upon successful calibration of the OPEN state the instrument will
proceed to step 2.
