Bench Type Digital Multimeter ( HTC – DM-8045R )

Description

The HTC DM‑8045R Digital Multimeter is a high‑precision, bench‑type instrument designed for laboratory, industrial, and advanced electronic diagnostics. Featuring a true 4½‑digit display with 19,999-count resolution, its large 30 mm backlit LCD ensures crisp visibility—even in dimly lit environments—as it displays dual measurements simultaneously via a VFD-style secondary readout. Its dual-display design allows concurrent viewing of two parameters or live trend tracking of min/max/average values.

With True RMS capability across all AC measurements, this multimeter handles non-sinusoidal waveforms and AC+DC combinations with accuracy that professionals demand. Its core is built around a double-integral A/D converter, ensuring stable digital conversion with minimal noise. Sampling is performed at approximately three readings per second, balancing responsiveness with stable output.

Its broad function coverage includes DC voltage up to 1000 V, AC voltage up to 750 V, DC/AC current up to 20 A, resistance up to 20 MΩ, capacitance up to 200 µF, and frequency up to 200 kHz. Additional features like diode test, transistor hFE test (0–1000), and continuity buzzer (under ~30 Ω ±10 Ω) make it a complete toolkit in one instrument.

Measurement accuracies are tightly specified:

1. DC voltage accuracy: ±(0.05% + 3 digits) at lower ranges and ±(0.1% + 5 digits) at full scale;

2. AC voltage: ±(0.8% + 80 digits) from 200 mV–200 V and ±(1.0% + 50 digits) up to 750 V;

3. DC current: ±(0.35% + 10 digits) at 20 mA, ±(0.8% + 10) at 2 A, and rated for short-duration 20 A use;

4. AC current: ±(0.8% + 80 digits) at 200 mA and ±(1.5% + 50 digits) at 2 A;

5. Resistance: ±(0.1% + digits) at low-ohm ranges and up to ±(0.5% + 5 digits) at 20 MΩ;

6. Capacitance: ±(3.5% + 20 digits) at low nF, ±(5.0% + 30 digits) at 200 µF;

7. Frequency: ±(1.0% + 20 digits) max.

Beyond accurate readings, the DM‑8045R offers several user-friendly functions: Data Hold, Auto Power-Off (after ~30 minutes), low‑battery alert, and auto‑polarity indication. Over-range conditions are clearly flagged with a “1” indicator, avoiding misreads. Input protection includes dual fuses for current ranges and robust overload shutdown protection. Anti-shock casing and IEC 61010 safety compliance support robust, safe use.

The unit houses comprehensive connectors and comes with full accessory support: test leads, power cord, and user manual, enabling instant deployment in labs or bench setups. It is sized to approximately 260 × 220 × 82 mm, weighing around 2 kg—making it stable on the bench, yet manageable for movable test environments.
