8-1 Measurement method
(1) Connect the test leads as the following figure shows.
・MODEL7260 to Line terminal
・MODEL7261A to Earth terminal
(2) Confirm the circuit under test is not energized, and measure
voltage with reference to 7. Voltage measurement .
(3) Confirm the voltage value which can be applied to the object
under test, and then set the function switch to a desired range.
● There is an empty range between 500V and 1000V for safety
purpose. If the function switch is set to this safety position,
the instrument doesn t start a measurement although the test
button is pressed down.
● Discontinuous warning buzzer sounds when the function switch
is set to 1000V range.
(4) Connect the earth test lead (MODEL7261A) to the earth terminal
of the circuit under test. The live warning LED blinks and buzzer
sounds if a voltage of 30V or higher exists in the circuit. Pressing
the test button in this state doesn t start resistance measurement.
(5) Place the tip of remote probe (line) to the circuit under test and
press the test button or remote control switch.
