Multimeter functions and ranges
- AC/DC voltage:
- DC up to 1000 V; AC up to 750 V (auto/manual range).
- AC/DC current:
- Ranges for mA and 10 A inputs (10 A MAX, 200 mA MAX inputs indicated in manual).
- Resistance:
- Up to 250 MΩ maximum range.
- Capacitance:
- 9.999 nF / 99.99 nF / 999.9 nF / 9.999 µF / 99.99 µF / 999.9 µF / 9.999 mF / 99.99 mF.
- Frequency:
- 9.99 Hz to 999.9 kHz with typical ±(0.1%+2) accuracy.
- Diode and continuity:
- Dedicated diode test and continuity with audible buzzer.
- Sampling:
- Real‑time sampling, about 3 readings per second; True‑RMS for AC voltage and current.
- General DMM features:
- Auto/manual range, data hold, backlight, auto power‑off, low‑battery icon.
Thermal imaging functions
- IR resolution: 32×32 pixels, interpolated to show on 2.4‑inch display.
- Temperature range:
- Approximately −20 °C to 550 °C with ±2 °C or ±2% accuracy.
- Field of view:
- About 33° × 33° fixed‑focus lens, recommended working distance around 0.3–2 m.
- Palettes:
- 4 color palettes such as Iron Red, Rainbow, White Hot, Black Hot.
- Emissivity:
- Adjustable emissivity via menu for better accuracy on different surfaces (accessed in settings; not a dedicated quick key).
- IR/data handling:
- Real‑time thermal display, image/data capture to internal storage, and PC access for exported files on some firmware versions.
Important Advantages
- Two tools in one: Reduces the need to carry a separate thermal camera and DMM, especially useful for field service and troubleshooting.
- Faster diagnostics: Thermal image quickly shows hot spots (overloaded components, poor connections, overheated breakers or MOSFETs) while immediate electrical measurements confirm the fault.
- High‑resolution DMM: 25,000‑count True‑RMS meter with wide voltage, resistance, and capacitance ranges supports detailed electronics and industrial measurements.
- Upgradeable platform: Firmware upgrades improve UI (e.g., wider graph display in multimeter mode) and fix bugs, extending product life.
- Designed for professionals: ABS+TPE housing, CE compliance, CAT‑style safety targeting electrician and industrial environments (specific CAT rating may vary by listing; check local documentation).
Typical uses
- Electrical maintenance and power systems:
- Locating overloaded breakers, loose connections, and phase imbalance by seeing temperature differences on panels and bus bars.
- Verifying voltage, current, and continuity on distribution boards, MCCs, and motor circuits.
- HVAC and building diagnostics:
- Checking motors, compressors, contactors, and wiring for abnormal heating and measuring supply voltages and currents.
- Inspecting under‑floor heating and localized insulation defects through thermal patterns.
- Electronics and PCB repair:
- Identifying shorted components, hot regulators, and localized heating on PCBs, especially in power and CPU sections.
- Standard DMM work (rail checks, component testing, frequency measurement) with visual confirmation of heat behavior.
