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.
