Metravi DT-425T is a handheld auto-ranging clamp meter having 4,000 counts 3 3/4 digit backlit LCD display. The circuit design of the instrument uses the large scale integrated circuit S/D analog digital converter as core, with the full-range over-load protection circuit and a unique appearance design, makes it a dedicated ‘Must-Have’ instrument. It is used to measure AC/DC Voltage, AC Current, DC Current, Resistance, Diode, Circuit on-off, Capacitance, Temperature, Frequency and Duty cycle, and it is also equipped with functions as data-hold, Maximum/minimum data measurement, relative value measurement, flashlight, NCV, under voltage display and Auto OFF. Liquid crystal display : 4000 Counts, 3-3/4 Digits Backlit LCD. Polarity display : Automatic positive and negative polarity display. Over-load display : Display in “OL” or “-OL”. Battery voltage display : When the battery voltage is lower than the working voltage, “ ” symbol will be displayed. Sampling rate : Approximately 3 times/second. Sensor type : Hall effect sensor. Measured position error : When measuring the current, ±1.0% additional error may occur if it fails to put the source to be measured on the central position of the clamp. Impact-resistant strength : 1 m height impact can be borne. Maximum opening dimension of clamp head : Diameter of 30mm. Electromagnetic field effect: When the electromagnetic field interference exists, it probably displays unstable or incorrect readings. Auto OFF function : 15m for automatic switch off; with disable function. Safety HOLD : Freezes the displayed data.
MAX / MIN : Records the maximum and minimum values displayed
REL : Helps to pertorun Relative measurement
FLIGHT : Switches the flash light ON to access dark areas.
