The instrument measures the voltage of an external circuit,
e.g., commercial power supply.
AC and DC are distinguished automatically.
3.3 Measuring Voltage
To prevent damage to the instrument and
personal injury, observe the precautions
below.
• Maximum rated voltage to ground: 1,000
V AC (CAT III), 600 V AC (CAT IV)
• Do not conduct measurement exceeding
these voltages to ground.
• Maximum input voltage: 750 V AC, 1,000 V
DC
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
instrument if the
shutter is broken.
Do not clamp two lines.
