Description

INSULATION / MULTIMETER ( HTC – DIM-1503 )

The HTC DIM‑1503 Digital Insulation Multimeter is a rugged, feature-rich handheld diagnostic tool engineered for electricians, maintenance professionals, and service engineers. It seamlessly integrates high-accuracy insulation resistance testing with full True RMS multimeter functionality—making it ideal for troubleshooting electrical systems, verifying safety compliance, and performing preventive maintenance.

At the heart of the DIM‑1503 lies a 5,999‑count, 3½‑digit display with True RMS AC/DC voltage and current measurement, ensuring reliable readings even in non‑sinusoidal or noisy environments. Its dual-integral A/D conversion delivers low-noise, high-stability performance across varied measurement modes. With automatic ranging and a large backlit LCD, users can switch between functions effortlessly while viewing readings clearly—even in dim workspaces.

The instrument offers comprehensive insulation resistance testing up to 2,000 MΩ at 1,000 V, with selectable test voltages typically at 250 V, 500 V, or 1,000 V. It provides accuracy of ±(4% + 2 digits), enabling precise evaluation of insulation in cables, motors, transformers, and panels.

As a digital multimeter, the DIM‑1503 supports a wide range of measurements: DC voltage up to 1,000 V (resolution from 0.1 mV to 1 V; ±(0.5 % + 5 digits) in lower ranges, and ±(1.0 % + 5 digits) at the 1,000 V level), and True RMS AC voltage up to 750 V with accuracy of ±(0.8 % + 10 digits) at lower ranges escalating to ±(1.0 % + 10 digits).

Current measurement covers DC and AC ranges from 6 mA to 20 A, with fine resolution (1 µA to 10 mA) and accuracy varying by range—about ±(0.8 % + 5 digits) for DC and ±(1.5 % + 5 digits) to ±(2.0 % + 5 digits) for AC depending on the scale.

Ideal for advanced diagnostics, it also measures resistance up to 60 MΩ (resolution from 0.1 Ω to 10 kΩ; accuracy between ±(0.8% + 5 digits) and ±(1.2% + 5 digits)), capacitance up to 60 mF, inductance, and frequency up to 10 MHz with duty-cycle analysis. Additional test functions include diode check, continuity buzzer, and non-contact voltage detection.

The DIM‑1503 supports temperature measurement via a Type-K thermocouple, spanning from –40 °C to 1000 °C (or 0–1832 °F) with 1 °C/°F resolution and accuracy of ±(1 % + 5 digits) across most ranges. This versatility makes it ideal for HVAC, motor winding, and environmental inspections.

User convenience is enhanced with features like Data Hold, Duty Cycle display, Auto Power-Off, low battery indication, and clear overrange (“OL”) display. The bright backlight and responsive interface support fieldwork under varied lighting conditions.

The device is built to endure: measuring approximately 200 × 92 × 50 mm and weighing around 480 g, it includes a shock‑proof cover, carrying case, test leads, temperature probe, battery, and instruction manual—ready for immediate deployment.

Ideal Applications:

• Insulation resistance testing of cables, motors, switchgear, and panels

• Combined coverage of multimeter functions: voltage, current, resistance, capacitance, frequency, duty‑cycle, diode, continuity, and NCV

• Temperature diagnostics in electrical control systems, HVAC, and mechanical maintenance
