Digital Multimeter


Heavy Duty T-RMS Industrial Digital Multimeter with TFT Display

DT-989

This is a heavy duty T-RMS Multimeter with TFT Color LCD Display, providing easy usage in dark area. The IP-67 makes the instrument dust and water proof and hence can be used in all kind of environments. The fast A/D converting sampling rate, high accuracy, built-in data logging, Trend capture and measurements with time stamp features makes the instrument versatile, reliable and the best tool for all industrial troubleshooting and maintenance work. This can be connected to iMM software on smartphone and cloud service can be used to keep data safe for future reference, thus helping field engineers to find and solve problems on production lines.

  • 5000 Counts colored TFT LCD Display, where multiparameters can be displayed.
  • It can measure AC+DC Voltage and Current. On the display the AC and DC Components of the signals are displayed.
  • While measuring AC Voltage and AC Current, Frequency and Duty Cycle are also displayed.
  • Has Maximum data record function.
  • Data Logging up to 100 Data and screen shots are possible.
  • Bandwidth up to 20KHz.
  • 4-20mA process loop measurement with % reading.
  • Min/Max/Avg reading with time stamp.
  • Peak Capture (records transients as fast as 250uS)
  • Trend Capture facility where the change in Voltage / Current with respect to time can be seen in the meter itself.
  • Blue Tooth Interface for Smartphone communication.
  • Online Help menu available in the instrument.
  • Auto Power Off function with disable facility also.
  • Battery Status indicator on the LCD Display.
  • Li-ion Rechargeable battery and battery charger provided with the meter.
  • 10A/1000V & 0.8A/1000V Fast Blow Fuse Protection.
  • Measured data can be stored in cloud service.

General Specification

Enclosure Double molded, waterproof
Shock (Drop Test) 6.5 feet (2 meters)
Diode Test Test current of 0.9mA maximum, open circuit voltage 3.2V DC typical
Continuity Check Audible signal will sound if the resistance is less than 25Ω (approx.), test current <0.35mA
PEAK Captures peaks > 1ms
Temperature Sensor Requires type K thermocouple
Input Impedance >10MΩ VDC & >9MΩ VAC
AC Response True rms
AC True RMS The term stands for “Root-Mean-Square,” which represents the method of calculation of he voltage or current value. Average responding multimeters are calibrated to read correctly only on sine waves and they will read inaccurately on non-sine wave or distorted signals. True rms meters read accurately on either type of signal.
