Meco 3690 Auto Digital AC/DC Clamp Meter

Product Id : 3843


Meco 3690 Auto Digital AC/DC Clamp Meter an electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, or tong tester (analyzer). This clamp meter can measure voltage, current, resistance, capacitance, temperature, frequency, and also the duty cycle. It has a large backlit LCD display for easier reading of measurements. It can also determine the true RMS value. It runs on a single 9V battery and also has an auto-power off function and low battery indication to save power. the digital meter measures DC voltage from 600mV to 1000V, AC voltage from 600mV to 750V, and resistance from 0 to 60M ohm.

Applications: Laboratories and Industrial Applications, Calibration Services.

Product Description

Meco 3690 Auto Digital AC/DC Clamp Meter estimates the vector sum of the currents flowing in every conductor passing through the probe, which relies on the phase relationship of the currents. a single conductor is normally passed through the probe.

Features Digital AC/DC Clamp Meter:

  • Display: 3¾ digit liquid crystal display (LCD) with a maximum reading of 3999.
  • Polarity: Automatic, positive implied, negative polarity indication.
  • Overrange: (OL) or (-OL) is displayed.
  • Zero: Automatic.
  • Battery Life: 150 hours typical with Carbon Zinc.
  • Low Battery Indications.
  • Overload 600 V DC/AC RMS.
  • Transformer Trigger: This is used to open the jaw.
  • Transformer Jaw: This is used to sense the current signal. To measure DC/AC current, Conductor must be enclosed by the jaw.
