เครื่องวัดความต้านทานดิน Earth Ground Resistance Tester

TES-1700: Digital Earth Tester ยี่ห้อ TES, Taiwan

Includes all hardware necessary to measure earth ground in 3 ranges from 0 to 3999Ohm

TES-1700 Digital Earth Resistance Tester without Tripping Earth Leakage Current 3 3/4 Digit LCD Display, TES-1700 is an Earth Ground Resistance Tester which includes all hardware necessary to measure earth ground in 3 ranges from 0 to 3999 omega. Also tests AC/DC Voltage, resistance and continuity. Featuring Automatic zero adjustment and three earth ground resistance ranges 39.9Ω/399.9Ω/3999Ω. Complete with test leads, 2 auxiliary earth bars, carrying case, protective rubber holster and eight x 1.5V AA batteries.

Features:

  • Capable of measuring earth voltage.
  • Data hold , MAX / MIN function.
  • Auto power off function: The timer operates automatically about 3 minutes when the " Test Button Switch " are pressed to keep the tester power on.
  • 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
  • In addition to the facility for precision measurement, test leads for simplified two wire measuring system also supplied as standard accessories.(unit can be hung from the neck for simplified measurement).
  • Automatic warning when resistance of auxiliary earth. Spikes is in excess of tolerance.
  • Designed to meet IEC1010-1 safety standard.
