To perform switch test with contact resistance measurement, select P-SWITCH and
proceed as follows:
INPUT
ZERO
To ensure accurate measurements it is recommended that the zero procedure (that
compensates for the resistance of the test leads) is carried out before performing this
test.
Note: Allow sufficient time after contact closure for the resistance to stabilize.
Connect Vin +, SW + and Connect Vin +, SW + and
mA in + together. mA in + together.
Connect switch test leads Connect switch test leads

Press ENTER to continue. Press ENTER to continue.
The switch test is performed in the same way as the previous
section, except that the contact resistance is measured and
displayed with the results.
