7 Output / input terminals
Output signal of the calibrator is connected to the output terminals. Current ranges are connected to +I / -I
terminals, frequency output is connected to FREQ terminal. All other functions (voltage, resistance,
capacitance) are connected to Hi / Lo terminals.
GND terminal is connected to the chassis of the calibrator. It is connected to the ground terminal of the mains
plug. Using the SETUP MENU of the calibrator, the output terminals of the calibrator can be grounded as well.
Grounding is done internally by connecting Lo and GND terminals using a relay. This circuit design is suitable
for most calibrations, when the object (multimeter) being calibrated is floating.
AUXILIARY connector creates input of internal multimeter. It includes a limited range of output signals of the
calibrator as well. The layout of individual pins and their meanings are listed in the following table.
Auxiliary connector can be used with one of cable adapters Opt. 40, 60, 70, Opt. 140-41. Calibrator can
recognize which type of adapter is connected and displays the information on front panel display.
