The tester measures the voltage of an exter-
nal circuit, e.g., commercial power supply.
AC and DC are distinguished automatically.
3.3 Measuring Voltage
To prevent damage to the tester and per-
sonal injury, observe the precautions
below.
• Maximum rated voltage to ground: 1,000
Vrms (CATIII), 600 Vrms (CATIV)
• Do not conduct measurement exceeding
these voltages to ground.
• Maximum input voltage: 750 Vrms, 1,000
VDC
• Do not conduct measurement exceeding
this maximum input voltage.
• Maximum input frequency: 70 Hz
• Do not conduct measurement exceed-
ing this maximum input frequency.
• Do not short-cir-
cuit a line voltage
applied with the
tip of test lead.
• Do not use the
tester if the shutter
is broken.
