Using the FUNCTION FUNCTION DOWN button one following functions can activated:
H igh resistance source
This the main function the calibrator.
Maximum safe voltage between terminal and GND terminal V. The terminal connected
inside the calibrator the low GND terminal.
G The metal terminal shielding terminal (equipotential). Using the SETUP MENU, the output terminals the calibrator can be
grounded floating.
Don’t exceed this limit !
A
G Ground terminal connected the chassis the calibrator. s. floated mode the terminal not connected to
protection earth.o. Grounded mode suitable for most calibrations, where the object (multimeter) being
calibrated floating (battery operated). M191 Insulation Tester Calibrator
L Low potential signal terminal signed The can used either grounded mode or
in floated mode. grounded mode the terminal connected protection earth and
calibrator housing via internal relay. enables set any resistance value specified
resistance range and connect the output terminals. Whole resistance decade floating the floating mode. Under standard condition should connected
to the shielding wire the test leads UUT.
