10KHz > 5MΩ. Clearing the impedance value outside the threshold does not work.
When measuring with a local jack, an external Kelvin clip, or an external table pen, it is necessary to
clear this connection mode. After the clear operation, the clear data with the conditions of the current
measurement method and the test level level* are saved. When the measurement is still done in this way, it
is not necessary to clear each time; when changing the measurement connection mode, the data must be
cleared again. Zero operation.
4.3.2 Zeroing the local measurement connector to clear theshort circuit:
Insert the shorting piece (or a good conductor) into the body socket to confirm that the connection is
good. When the display is stable, press C and the series parameter is zero or minimum. 0.XXXmΩ+

0.000uH.
Open circuit clear: open the socket, without inserting any components. When the display is most stable,
press C. The parallel parameter is the largest and the display is >1000MΩ// 0.000P.

4.3.3 Kelvin Test Clip Clear
When using the Kelvin clip measurement method to clear or measure, the two test wires should be
stranded. This approach helps to reduce the uncertainty of the test line's parasitic parameters due to
changes in the attitude of the test line. Sex, especially when measuring low impedance or high impedance,
should be twisted. For intermediate impedance, stranding is not so important.
Specially pointed out that when the two clips of the Kelvin clips are snapped to one another and are
short-circuit-cleared, attention should be paid to following the order of the terminal names shown in Fig.
9, that is, the current terminal is next to the current terminal, and the voltage terminal and the voltage
terminal are next to each other. Do not alternate. For self-made external test leads, refer to 4.5.4.
