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.
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.
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
