2. GENERAL DESCRIPTION

The clamp meter HT9022 carries out the following measurements:

• DC voltage and AC+CD TRMS voltage

• DC current and AC+CD TRMS current

• Phase sequence

• Active, reactive, apparent power and power factor on single-phase and/or balanced

three phase systems

• Active, reactive, apparent energy on single-phase and/or balanced three-phase

systems

• AC voltage harmonics (1

st

– 25

th

) and THD% up to 75Hz (1

st

– 8

th

above 75Hz)

• AC current harmonics (1

st

– 25

th

) and THD% up to 75Hz (1

st

– 8

th

above 75Hz)

• DC power

• Frequency on voltage (leads) and current (clamp jaw)

• Resistance and continuity test with buzzer

• Electric motor starting currents (INRUSH)

• Detection of presence of AC voltage with and without contact with in-built sensor in the

clamp jaw

Each of these functions can be selected using the 7-position selector switch, including an

OFF position.

Keys F1, F2, F3, F4 e H / are also provided; for their use, please refer to § 4.2.
