HT Italia HT77N AC Clampmeter for Measuring Leakage Currents 10µA to 100A

تحقق من مصدر بلدي HT_Italia_Ca The HT77N clampmeters is designed for accurate measurement of very low values of AC currents and, therefore, they are mainly employed in detecting and and defining leakage currents in private and industrial electric systems, which typically cause RCDs’ tripping. The 50/60Hz integrated low pass filter permits the cut off of high order harmonics. Some alarm threshold are selectable of the HT77N meter with buzzer sound during measurements and sophisticated automatic backlight sensor is provided to perform correct test in dark environments. The meter is compliance to IEC/ EN 61010-1 safety standard in CAT III 300V. Functions:

  • True RMS current up to 100A.
  • 50/60Hz Low Pass filter.
  • Threshold alarm on measurements.
  • Data Hold, Auto Hold, Peak Hold.
  • Manual and Auto ranging.
  • Automatic backlight sensor.
  • Backlight.
  • Auto Power Off.
  • Maximum conductor size 40mm.

انقر على المصدر The innovative model HT Italia HT77N is a clamp meter for accurate measurements of very low AC current values. It is mainly employed in measuring leakage currents causing typical problem of RCDs accidental tripping on civil and industrial electrical installations. The built-in 100Hz low pass filter permits to cut off harmonic components. Some alarm thresholds can be selected on HT77N with acoustic indications depending on the measured current values. It is also provided with a sophisticated automatic backlight sensor to perform testing in dark environments. The meter complies with IEC/EN61010-1 safety standards under CAT III 300V.
