Frequently Asked Questions
Q: What is the difference between the LAOLAU TS26A and TS26D clamp multimeters?
A: The TS26A adds an Inrush Current measurement mode, making it ideal for capturing high startup surges in HVAC systems, industrial motors, and compressors. The TS26D is optimized for precision DC current profiling, making it the better choice for solar panels, electric vehicles, and other DC-powered systems. Both share the same True RMS engine, HD color display, phase sequence testing, USB-C charging, and 6,000-count resolution.
Q: How does the phase sequence test function work on the TS26 clamp meter?
A: The phase sequence (phase rotation) test determines the rotational order of the three voltage phases (R/S/T or L1/L2/L3) in a polyphase AC power system. A correct sequence shows an "R" symbol with a green indicator light; a reversed sequence shows an "L" symbol with a red indicator light. This helps ensure three-phase motors spin in the correct direction and prevents equipment damage from incorrect wiring.
Q: How long does the battery last, and how is it charged?
A: The built-in 3.7V Li-ion battery delivers 50+ hours of runtime on a single charge. It recharges via the included USB-C cable — the same connector used by most modern smartphones and laptops — so you're never stranded without power on the job.
Q: Is the LAOLAU TS26 clamp meter safe for high-voltage electrical work?
A: Yes. The TS26 series is rated CAT III 1,000 V / CAT IV 600 V, meeting internationally recognized safety standards for electrical measurement in industrial, commercial, and residential environments. It is also CE and RoHS certified.
Q: Can the TS26 multimeter measure temperature?
A: Absolutely. Using the included K-type thermocouple probe, the TS26 measures temperatures from -40°C to 1,000°C, making it suitable for HVAC compressor diagnostics, automotive thermal checks, industrial machinery monitoring, and renewable energy system assessments.
