KEY
Key function
ON/OFF (Standby)
Switches the processor section of the instrument on and off.
In standby mode the analog electronic circuits are still powered up,
i.e. the instrument is ready sooner for operation with full
accuracy after switch-on.
VDC
Direct voltage measurement (numerical: 1)
VAC
Alternating voltage measurement as true RMS without DV component
(numerical: 2).
VAC+DC
(2nd + VAC)
Alternating voltage measurement as true RMS with DV component.
IDC
Direct current measurement (numerical: 3).
IAC
Alternating current measurement as true RMS without DC component.
(numerical: 4).
IAC+DC
(2nd + IAC)
Alternating current measurement as true RMS with DC component.
FREQ
Frequency measurement for Vac and Iac (numerical: 5).
PERIOD
(2nd + FREQ)
Period duration measurement for Vac and Iac.
Ω
2W
2-wire resistance measurement (numerical: 6).
Ω
4W
4-wire resistance measurement (numerical: 7).
TEMP
Temperature measurement with a preselected sensor,
repeated pressing of this key cycles through °C, °F and Kelvin
(numerical: 8).
CONT
Continuity testing
2nd
Switches over for the blue legend under the keys.
TRIG (2 x 2nd)
Executes a manual trigger.
