⑵ Terminal block
Connect the attached mains cord and Test Leads to this terminal block.
⑶ Terminal for mains cord
This terminal is connected to a mains supply via M7123.
⑷ Terminal for Extension leads adaptor
It corresponds to L, N, E of test socket, and the extension leads adaptor
(M-7140) connected with the cord reel to be plugged to it.
⑸ PE-probe terminal
Connect the Test Lead with alligator clip (M-7129A)(13) to this terminal for
the measurement of protective conductor resistance, and clip the metal
parts of DUT with the alligator clip.
⑹ LCD
Measured value is displayed
⑺ LED for test result
When the value of protective conductor resistance and insulation
resistance exceeds the limit dictated by applicable standards, LED lights up
in red. When it is within the limit, LED lights up in green.
⑻ Start/Stop switch
A measurement starts by pressing this switch.
Pressing the Start/Stop Switch again during Leakage Current Test stops
measurements.
⑼ Null/250V-500V switch
• Class I test measurement
It is used in order to push the Null button before protection earth
resistance measurement and to cancel the resistance of a test leads.
• Class II test measurement
The test voltage of insulation resistance is changed to 500V and 250V.
⑽ Function switch
Select a function with this switch.
⑾ SELECT switch
When the function is set under SELECT switch is pressed, the appliance
will be actually operated to measure a leakage current instead of
measuring insulation.
