Digital Multimeter ( Insulation ) ( HTC – DIM-1502 )

Description

The HTC DIM‑1502 Digital Insulation Multimeter is a highly versatile and rugged handheld testing instrument combining insulation resistance measurement with full multimeter functionality. Designed for field electricians, industrial technicians, and maintenance professionals, it integrates insulation testing up to 2000 MΩ, full True RMS voltage and current measurement, temperature sensing, continuity detection, and logging features in one robust tool.

With a 5,999‑count display and True RMS capability for both AC and DC measurements, this device ensures precise readings in complex electrical environments. It supports DC voltage ranges from 600 mV to 1000 V, with resolution from 0.1 mV to 1 V, delivering accuracy up to ±0.5% + 5 digits in lower ranges and ±1.0% + 5 digits at high voltage levels. AC voltage measurement extends up to 750 V with similar resolution increments and ±0.8% + 10 digits accuracy, ideal for testing in industrial power circuits

The insulation resistance testing ranges from 300 MΩ to 2000 MΩ, supporting measurements at various test voltages (like 250 V, 500 V, 1000 V), with a specified test accuracy of ±(4% + 2 digits). This enables technicians to assess the integrity of insulation in cables, motors, transformers, and high-voltage equipment with confidence.

In addition, the unit handles DC current up to 20 A, including finer ranges (6 mA, 60 mA, 600 mA, 6 A), with resolution down to 1 µA and accuracy around ±(0.8% + 5 digits) across current ranges. Capacitance testing spans from 60 nF to 60 mF, with resolution from 10 pF up to 10 µF, suitable for circuit component testing and filter diagnostics.

The multimeter portion also covers resistance ranges from 600 Ω to 60 MΩ, with resolution steps from 0.1 Ω to 10 kΩ—ideal for electronics diagnosis, continuity verification, and circuit testing. Built-in frequency measurement (up to ~50 kHz) automatically displays AC voltage when frequency is detected, and duty cycle is supported to evaluate PWM or switching signals.

Temperature measurement via thermocouple covers −40 °C to 1000 °C (or 0–1832 °F) with 1 °C/°F resolution, offering high accuracy (±1% +5 digits below 400 °C) across broad temperature applications from motor windings to HVAC diagnostics.

User-friendly operation is enhanced by advanced features including Data Hold, duty cycle display, auto power-off, dual-integral A/D conversion, backlit display, low-battery detection, max‑range overload protection, and continuity/diode function. It also includes audible alerts for continuity and over-range warning displays, ensuring safe and practical usage in the field.

Compact and durable, the DIM‑1502 measures approximately 200 × 92 × 50 mm and weighs around 480 g, including batteries. Accessories include insulated test leads, a shockproof cover, carrying case, a TP‑01 temperature probe, battery, and user manual—ready for immediate field deployment.
