Item Description
A
Input HI and LO connectors. Input connectors for Volts, 2-wire Ohms, Hz, Period,
Temperature, and Capacitance measurements. Input connectors source current
for 4-wire Ohms measurements. All measurements use the Input LO connector as
a common input. The LO input is isolated, and may be safely floated up to 1000 V
above earth ground regardless of the measurement type. 1000 V is the maximum
voltage rating between the Input HI and LO connectors and between each HI and
LO input and earth ground.
B
Sense HI and LO connectors. Sense connectors sense the voltage across the
unknown resistance for 4-wire Ohms measurements or provide the DCV
reference Input for DCV Ratio measurements.
C
Soft keys F1 through F5. Soft keys are used to select various menu options while
navigating the Meter’s menus. Each soft key’s function is identified with a label in
the bottom row of the display. Keys without a label above them are inactive
