Digital Multimeter


Professional T-RMS Industrial Multimeter

DT-9989

Advanced diagnostic and logging functionality for maximizing productivity

The DT-9989 represents the next generation of high performance industrial logging multimeters, including higher accuracies and greater troubleshooting convenience than ever before. With the ability to log data and review it graphically on large colored display, you can solve problems faster and help minimize downtime, while working at several locations.

The DT-9989 incorporates a built in 10MHz DSO that is the rugged solution for industrial troubleshooting and installation applications. It’s a truly integrated test tool, with oscilloscope, multimeter and “paperless” recorder in one affordable, easy-to-use instrument. Find answers to problems in machinery, instrumentation, control and power systems quickly and easily. 

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

AC Response True RMS
AC True RMS The term stands for “Root-Mean-Square” which represents the method of calculation of the 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.
