5.4 Frequency measurement
To perform frequency measurement:

set the rotary switch at Hz% ,

connect black test lead to COM terminal, and red test lead to
V
Ω
Hz%CAPTemp terminal,

contact the tips of test probes to the points of measurement,

read the measurement result on the display.
See also sec. 6.3.2.
5.5 Measurement % of duty cycle (pulse filling indicator)
To perform the measurement:

set the rotary switch at Hz% ,

press MODE button, until symbol % is shown on the display,

connect black test lead to COM terminal, and red test lead to
V
Ω
Hz%CAPTemp terminal,

contact the tips of test probes to the points of measurement,

read the measurement result on the display.
5.6 Measurement of resistance
WARNING
Do not perform measurements on the circuit under the
voltage. Before the measurement disconnect the pow-
er and discharge capacitors.
To perform measurement of resistance:

set the rotary switch at
Ω
,

connect black test lead to COM terminal, and red test lead to
V
Ω
Hz%CAPTemp terminal,

contact the tips of test probes to the points of measurement; the
best solution is to disconnect one side of the tested element, to
prevent the remaining part of the circuit interfere with the read-out
of the resistance value,

read the measurement result on the display.
