VFD mode (Variable-Frequency Drive)
NOTICE
The VFD mode filters out noise
providing a more stable reading when measuring
voltage on variable frequency drives. The voltage
range in the VFD mode is 50 V to 700V AC.
• In AC voltage measurement mode, press and
hold the MODE button (D) for 2seconds. The
VFD indicator (15) lights up.
• Connect the test probes (Q) in parallel to the
circuit or device under test.
• The stabilized value on the display (A) is read as
the actual reading.
NOTICE
Press the MODE button (D) for
2seconds to return to normal operation. The VFD
indicator(15) goes off.
