Key Sequence Examples (characters in [ ])
Example 1: Supply the meter with a value of 27.39mH
1) Select the following settings in MEASUREMENT MODE:
AC Meas, L, Q, Parallel, Show Scale, %.
2) Using the and keys, highlight the nominal parameter (underneath the left-hand-side of
the scale).
3) Key the following sequence:
[.] [0] [2] [7] [3] [9] [Units] [H] check data entry line is correct, then press [Enter]
or
[2] [7] [.] [3] [9] [Units] [m] [H] [Enter]
If a mistake is made in a key sequence, before pressing Enter, press to delete the last key
press or Clear to delete the whole key sequence.
Example 2: Set the frequency to 100 kHz
1) Using the and keys, highlight the selected frequency.
2) Key the following sequence:
[1] [0] [0] [0] [0] [0] [Enter]
or
[1] [0] [0] [Units] [k] [Enter]
or
[.] [1] [Units] [M] [Enter
4.3 Trimming
The purpose of trimming is to eliminate the effects of stray capacitance or series impedance in
the connecting leads or fixture.
The trim values are held in non-volatile memory and for most measurements no retrimming is
necessary. The exceptions are when the lead set or fixture is changed; when the highest possible
accuracy is required for measurements of very high or very low impedances.
Depending on the trim option selected, the meter trims by making measurements at a number of
frequencies, including the measurement frequency in use when the trim was initiated, and
storing the corrections for each. If the measurement frequency is changed the meter
automatically applies a new correction value by interpolation of the stored values.
For O/C Trim the Kelvin clips or fixture jaws should be separated by a distance equivalent to
the DUT pin separation.
