Performing the Measurement
Connect the desired test lead (either test lead with
shockproof plug or three individual test leads) to
the test instrument. Here connect the black test
lead to the black socket 'L/L1' (24), the blue test
lead to the blue socket 'N / L2' (25), and the green
test lead to the green socket 'PE / L3' (26).
Switch on the UNITEST 0100-ELECTROcheck
using the rotary switch 'Measurement Function'
(19) and set the rotary switch to the measure-
ment function 'Loop Resistance'. The test in-
strument indicates the following:
Figure 5.4.1 Instrument ready for operation
Now, connect the desired test leads to the UUT.
Please refer to Figure 5.4.2 or Figure 5.4.3 for
connection.
