Clamp Meters

GAOTek’s clamp meters are made to be high in quality and high accuracy readings which can be done in an effective and efficient way. GAOTek provides various types of clamp meters that are versatile for measuring vector sum of the currents. Moreover, they have simple operation with precise measurements which can ensure that our customers will be satisfied when using our products.

Technologies

A wide variety of clamp meter are used for routine use, and in highly specialized projects. These devices are used to hold and secure objects tightly together to prevent movement or separation. Generally, a clamp meter is composed of five different components: clamp, clamp button, dial screen, and cable sockets. The clamp button is used to control the clamp, and the dial is for the selection of measurement the clamp meter would use. The screen is where the measurement is displayed, and the cable sockets are desired for common input jack and volts/ohm input jack.

Features

GAOTek’s clamp meters are easy-to use and can accurately read measurement due to its key features such as:

  • Large backlit display, frequency, ac and dc voltage, resistance, continuity, and min/max
  • Data logging which is used to identify broken faults by logging any power quality parameter
  • Alarm limits for rapid pass/ fail type measurement
  • Rugged and durable to make measurements easily in tight cable compartments
  • Accurately measure frequency of current and voltage up to 1 kHz
  • Measure true-rms voltage, capacitance, resistance, and continuity
  • Broad range of measurement, from 1 µA up to 60 A, for all installation needs
  • Advanced shielding to ensure accurate results when measuring near other conductors
  • High precision of measurements, high resolution and quick sampling speed
Applications

Clamp meters are widely used in many industries, but they are especially useful for electrical maintenance. Some examples where clamp meter are used by contractors, electricians and building maintenance are:

Working on Panels and Branch Circuits

  • Measure loads on a branch circuit at a panel and the continuity of fuses, switches, and contacts
  • Measure load side voltage of a breaker or fuse
  • Check if a circuit is live before beginning work

Verify Circuit Integrity and Operation

  • Measures ac voltage, load current, and continuity of contacts, switches and fuses

Feeder Cables

  • Check balance and loading of feeder cables

Working with Drives and Motors

  • Measure motor start-up and run current
  • Measure the output of variable speed drives and motors

In and around the Service Panel

  • Clamp around bus bar or conductors to measure loads and line frequency in feeders and circuits

Measure ac or dc current

  • Measure ac or dc for use in battery-operated systems like UPS or other dc systems

Service Entrance, Service Panel, and Low Voltage Vaults

  • In the service panel, clamp around each distinct phase. (Excellent for large single or parallel conductors)
  • In the service entrance, clamp around bus bars, up to 2.5 in, to verify expected current usage
  • Measures current in conductors of low-voltage vaults (1000 V or less)

Working with Large Loads

  • Verifying operations of large current DC systems, large load service panels, switchgears, and motors

Checking Furnaces and Boilers

  • Capture flue gas temperatures and perform flame rod testing

HVAC Motors and Drives

  • Measure, run and start motor capacitors
  • Troubleshoot compressor electrical motor faults
  • Measure performance of variable frequency drives

Testing Electrical Performance

  • Measure supply-side and load-side current and voltage
  • Measure current and voltage phase balance on 3 phase systems
