Digital Inrush Clamp Meter Multimeter Temirup T-rms Review

Safety first: a clamp meter measures current on conductors that may be live at mains voltage. The Temirup listing states a 600 V overload protection and a 600 V maximum input. The Amazon listing gives no measurement category. A manufacturer-side page for the same model states one (see the source note below), but confirm the rating on the meter itself before any household mains or panel use. Panel and service work belongs to a licensed electrician.

The person typing “digital inrush clamp meter multimeter temirup t-rms review” is considering one specific clamp meter. This review covers what the listing states and what it leaves out.

This review is based only on the Amazon listing and its specification fields. We have not tested this meter.

Quick answer

The Temirup CM87C is a battery-powered clamp meter with True RMS, 6000 counts, a 600 A AC/DC current range, an inrush-current function, and a 30 mm jaw. The listing also describes voltage, resistance, capacitance and continuity measurement through test leads. The Amazon listing does not state a CAT rating. A manufacturer-side product page for the same model number (CM87C, on the Mestek Instruments site) states CAT III 600 V under IEC/EN 61010-1, so the rating is published, but confirm it on the label of the meter you receive.

What the listing states

  • Current: AC/DC current through the clamp, up to 600 A, with a 30 mm jaw.
  • Display: 6000 counts, a large LCD, and a backlight with auto-off after about 3 minutes. The listing gives a maximum display value of 5999.
  • True RMS: the title and bullets describe True RMS measurement.
  • Inrush: an inrush current function, plus low-impedance (LoZ) and variable frequency drive (VFD) filter modes, per the bullets. The inrush bullet includes the note “Only Measures AC”; the rest of that bullet is cut off in the listing copy, so check the manual before using inrush on a DC load.
  • Voltage: AC/DC voltage, with a maximum input of 600 V AC or DC and overload protection at 600 V, per the spec table.
  • Other functions: capacitance, resistance, continuity with a buzzer, data hold, and a temperature probe.
  • Power: 2 AAA batteries (the spec table lists 2 x 1.5 V AAA). Auto-shutdown after about 15 minutes.
  • Weight and size: about 240 g without batteries; 218 mm by 75 mm by 39 mm.
  • Specification met: CE and RoHS.
  • Included: clamp meter, two multimeter pens, a temperature probe, and two batteries.

What the listing does not state

  • A CAT rating on the Amazon listing. The listing gives a 600 V maximum input and 600 V overload protection, but no measurement category. A voltage maximum is not a CAT rating. The Mestek page for the CM87C states CAT III 600 V, which is a separate source from the listing.
  • A jaw-rating or insulation class. The listing does not state the jaw insulation rating.
  • Its listing’s own warning. The bullets note that when measuring current, you should clamp around a single conductor. Follow that note.

How it compares on the listing

Compared with the Klein CL120 and the FNIRSI DMC-100 clamp meters, the Temirup lists the inrush function and a 600 A range (the Klein lists 400 amps). Its Amazon listing states no CAT rating, and neither do the FNIRSI or Klein meter listings. The FNIRSI lists “UL 61010-1″ as its safety approval; the Klein lists “Double Insulation Safety Rating,” and its test leads are described with “CAT III/CAT IV safety caps.” Those leads are not the meter, so the Klein meter itself has no stated CAT rating.

Who this meter suits

  • An automotive or appliance user who wants AC/DC current on low-voltage circuits and the inrush function.
  • A DIYer who measures current on equipment and understands the limits of the listing’s safety information.

Who should skip it

  • Anyone who needs a CAT rating stated for household mains or panel work.
  • Anyone who wants a clamp that the listing describes for industrial or commercial installations. The listing does not describe those uses.

How we judge a clamp meter

We check the listing for current range, jaw size, True RMS, the presence of a CAT rating, and whether the bullets are consistent with the spec table. The Temirup listing is consistent on current range, jaw size and battery type. The missing CAT rating is the main reason to look for a clamp that states one.

Key numbers from the listings

  • Current: up to 600 amps AC/DC through a 30 millimeter jaw.
  • Voltage: 600 volts maximum input and 600 volts overload protection, per the spec table.
  • Display: 6000 counts; backlight auto-off after about 3 minutes; auto-shutdown after about 15 minutes.
  • Power: 2 x 1.5 volt AAA batteries.

For example, a 600 amp range leaves room for large currents, but the listing does not give the accuracy at the top of the range. Use the lowest range that fits the reading, and check the manual for the accuracy at each range.

Source

The CAT III 600 V figure above comes from the manufacturer-side product page for the same model: Mestek: CM87C clamp meter. That page also lists AC current up to 600 A, AC voltage up to 600 V, inrush current at 600 A, and a K-type temperature range of -20 °C to 1000 °C. It is a seller-side page, not an independent test, so treat it as the stated rating, not a verified one.

FAQ

Does the Temirup CM87C have a CAT rating?

The Amazon listing does not state one; it gives a 600 V maximum input and 600 V overload protection, which are not a CAT rating. The Mestek product page for the CM87C states CAT III 600 V under IEC/EN 61010-1. Check the label on your meter.

What is the inrush function for?

The listing describes it as measuring inrush current. Inrush is the short-lived high current a motor or load draws when it starts, and the listing does not describe a specific application for it beyond that.

Can I measure both wires of a cord with it?

The listing says to clamp around a single conductor when you measure current. Clamp one conductor at a time.

Which batteries does it use?

The spec table lists 2 x 1.5 V AAA batteries. The included items list two batteries.

Conclusion

The Temirup CM87C lists a True RMS clamp with a 600 A range, an inrush function and a 30 mm jaw. The Amazon listing gives no measurement category, so confirm the rating on the meter before any household mains or panel use. Check the current price and the manual before you buy.
