Metravi DT-115 Digital TRMS AC Clamp Meter

A. Product Overview

The Metravi DT-115 is a pocket-sized Digital True RMS AC Clamp Meter developed for electrical testing, troubleshooting and preventive maintenance. Its clamp-style design allows technicians to measure AC current without opening the circuit or making direct electrical contact with the conductor.

The meter provides a maximum display of 5999 counts and uses an auto-ranging measurement system for convenient operation. It can measure:

• AC current up to 600A
• DC voltage up to 1000V
• AC voltage up to 750V
• Resistance up to 40 megaohms
• Capacitance up to 30 millifarads
• Frequency up to 10MHz
• Temperature from minus 20 degrees Celsius to 1000 degrees Celsius
• Diode condition
• Electrical continuity

The DT-115 also includes True RMS measurement, non-contact voltage detection, data hold, relative measurement, low-battery indication, overload indication, a backlit LCD and a flashlight for working in dark or confined areas. The supplied Type K thermocouple probe supports temperature measurement.

B. Working Principle

The Metravi DT-115 uses different measurement principles depending on the selected function.

AC Current Measurement

For AC current measurement, the clamp jaw is placed around a single current-carrying conductor. The alternating current flowing through the conductor creates a magnetic field. The meter detects this magnetic field and converts it into an electrical reading displayed in amperes.

Because the conductor does not need to be disconnected, current can be checked quickly with minimal interruption to the electrical system.

AC and DC Voltage Measurement

For voltage testing, the supplied test leads are connected to the meter and placed across the two measurement points. The internal analogue-to-digital conversion circuit processes the input voltage and displays the measured value on the LCD.

True RMS Measurement

The True RMS function calculates the effective value of an AC waveform. This provides more reliable measurements when testing non-linear electrical loads or distorted waveforms produced by equipment such as variable frequency drives, electronic power supplies and modern control systems.

Resistance, Continuity and Diode Testing

The meter applies a small internal test signal through the connected component or circuit. It then measures the electrical response to determine resistance, continuity or the forward-voltage drop of a diode.

During continuity testing, the buzzer sounds when the measured resistance is sufficiently low, helping technicians locate closed circuits and electrical connections.

Capacitance and Frequency Measurement

The DT-115 evaluates the charging behaviour of a capacitor to calculate capacitance. For frequency measurement, it counts the number of repeating signal cycles within a defined period and displays the result in hertz.

Temperature Measurement

The supplied Type K thermocouple probe generates a small voltage based on the temperature difference at the probe tip. The meter processes this signal and displays the temperature in degrees Celsius or degrees Fahrenheit.

Non-Contact Voltage Detection

The non-contact voltage detector senses the electric field around an energised AC conductor. This helps the user perform a preliminary check for the possible presence of AC voltage without directly touching the conductor with test probes.

C. Why It Is Used

The Metravi DT-115 is used to perform multiple electrical measurements with one portable instrument. Its clamp-based current measurement helps technicians check AC current without cutting, disconnecting or disturbing the conductor.

It is commonly used for:

• Measuring current drawn by motors, pumps, compressors and electrical equipment
• Checking AC and DC supply voltage
• Troubleshooting electrical panels and distribution systems
• Testing wiring continuity
• Measuring resistance in components and circuits
• Testing capacitors
• Checking diodes and semiconductor components
• Measuring electrical signal frequency
• Measuring equipment, surface or process temperature with the thermocouple probe
• Detecting the possible presence of AC voltage
• Comparing measurements by using the relative mode
• Holding unstable or difficult-to-view readings on the display

Its True RMS capability is particularly useful when measuring electrical systems containing distorted or non-sinusoidal AC waveforms.

Frequently Asked Questions

1. What is the maximum AC current range of the Metravi DT-115?

The Metravi DT-115 can measure AC current up to 600A. Its available AC current ranges are 6A, 60A and 600A.

2. Does the DT-115 measure DC current?

No. The catalogue specifies AC current measurement. The meter measures both AC and DC voltage, but its clamp-current function is designed for AC current measurement.

3. What does True RMS mean in a clamp meter?

True RMS means the meter calculates the effective value of an AC waveform. This helps provide more reliable readings when the waveform is distorted or non-sinusoidal.

4. What is the maximum voltage measurement range?

The DT-115 measures DC voltage up to 1000V and AC voltage up to 750V.

5. Can the DT-115 measure temperature?

Yes. It measures temperature from minus 20 degrees Celsius to 1000 degrees Celsius and from 0 degrees Fahrenheit to 1832 degrees Fahrenheit. A Type K thermocouple probe is included with the meter.

6. Does the meter have non-contact voltage detection?

Yes. The DT-115 includes a non-contact voltage detector for preliminary identification of the possible presence of AC voltage.

7. Can it test capacitors?

Yes. The meter measures capacitance from 60 nanofarads up to 30 millifarads, depending on the selected range.

8. Does the DT-115 have a continuity buzzer?

Yes. It includes an audible continuity test. The buzzer sounds when the measured circuit resistance is within the specified low-resistance threshold.
