Front Panel
RANGE dial
Switches the voltage, current,
resistance, and temperature
ranges.
→ sec. 5.1, 6.1
When SETUP is selected, a
SETUP menu appears.
→ ch. 4, sec. 6.5, 6.6, 7.3, 8.3,
9.3, 13.5, 13.7 to 13.9
Output setting display
Displays the value set with the output setting dials. 5.5-digit
7-segment LEDs are used.
→ sec. 5.2, 6.2
While in the SETUP menu, these display the menus at different
hierarchical levels. At levels where a value is set or displayed,
these display the value.
→ ch. 4, sec. 6.5, 6.6,
7.3, 8.3, 9.3, 13.5, 13.7 to 13.9
Polarity display
Displays the polarity set with the
POLARITY switch
→ sec. 5.2, 6.2
POLARITY switch
Flip the lever up or down to set the
polarity.
→ sec. 5.2, 6.2
While in the SETUP menu, this

current, resistance, or tempera-
ture (thermocouple or RTD) is
being generated
→ sec. 5.3, 6.3
