5.5 Measurement % of duty cycle (pulse filling indica-
tor)
To perform the measurement:
 set the rotary switch at
 press MODE/VFD button, until symbol % is shown on the display,
 connect black test lead to COM terminal, and red test lead to
VΩCAP
 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 ΩCAP,
 connect black test lead to COM terminal, and red test lead to
VΩCAP
 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.
