Technical index of diode and on-off test
Overload protection: 250V DC or AC peak.
Note:
·If circuit under measurement is in open-circuit mode,
the display screen will show "OL".
When testing circuit on-off, cut off its power and fully
discharge capacitance.
·After measuring, disconnect test lead
from circuit under measurement immediately.
2-5.AC measurement (see Figure 6)
A)Rotate function/range selection switch to "2/20A" or
"200/600A".
B)Press and hold clamp jaw trigger to open clamp jaw. Pick up conductor under measurement by clamp
jaw, then release trigger slowly until clamp jaw is fully closed. Please make sure the conductor is in the
center of clamp jaw, otherwise it will cause additional error. The clamp meter can only measure one
current conductor at one time. If measuring two or more conductors at the same time, the readings will be
incorrect.

Description
Open-circuit voltage is
about
1.4V,
forward
voltage drop is about
0.5~0.8V.
Open-circuit voltage is
about 0.45V, when it is
lower than 70Ω, the
buzzer beeps.
