Measuring function
CLiP=OFF: alternating voltage, AC TRMS, full bandwidth
(0/2) CLiP=ON: alternating current via current clamp sensor, TRMS AC value
(1) CLiP=oFF: voltage frequency, to 300 kHz / CLiP=ON current frequency sensor
Alternating voltage, AC TRMS, with low pass filter (1 kHz)
Alternating voltage level measurement
(0/2) CLiP=OFF: direct voltage measured directly / CLiP=ON: via current clamp sensor
(1) CLiP=OFF: pulsating voltage, direct, TRMS / CLiP=ON: via current clamp sensor
Direct voltage events
Alternating voltage events
Mains quality: events (type, start time, date, duration, value)
Main display: total harmonic distortion relative to fundamental frequency as %
(0/2) Auxiliary display: RMS value for the total signal in V
(High) Frequency at 5 V~ up to 1 MHz
Duty cycle at 5 V~
(DC) resistance
Conductivity (in nano-Siemens)
Low-resistance measurement with acoustic signal where Iconst = 3 mA
Continuity test, , with acoustic signal where Iconst = 1 mA
Diode voltage up to max. 6 V where Iconst = 1 mA
Temperature, type K thermocouple
Temperature with Pt100 / Pt1000 resistance sensor
Capacitance
Cable length
Power (active, reactive, apparent power) / voltage + current / power factor
Mean: average power / max: maximum power
(2) CLiP=OFF: pulsating current, direct, TRMS AC+DC, CLiP=ON: current clamp transformer
(3) CLiP=OFF: direct voltage, direct, CLiP=ON: direct voltage via current clamp trans.
(0/4) CLiP=OFF: alternating current direct, TRMS AC / current frequency,
CLiP=ON: alternating current via current clamp trans. // temperature: MB 6 A and 10 A
(1) Main display: total harmonic distortion relative to fundamental frequency as %
Auxiliary display: RMS value for the total signal in A
