Digital Multimeter with True RMS

The Tenmars TM-87 is a digital multimeter designed for electrical testing up to 1000V. It provides True RMS measurement for accurate AC readings. The meter carries a CAT IV 600V and CAT III 1000V safety rating. An LCD with 3999 counts and an analog bargraph display the values.

Suited for electricians and high-energy panels

This meter suits electricians and technicians working on mains supply or distribution panels where CAT IV 600V protection is required. True RMS supports non-linear loads such as variable speed drives. It is not suited for buyers who need temperature measurement or higher resolution than 3999 counts.

CAT IV 600V safety rating

The decisive specification is the CAT IV 600V overvoltage category combined with 1000V input protection. This rating permits measurement at the service entrance and on primary supply circuits. Verify that your working environment demands this category before purchase.

Questions about this item

What test leads and power source are required before using the TM-87?

The meter ships with test leads and a carrying case; a 9V battery is not included and must be supplied separately.

Will the TM-87 measure voltage safely on a legacy CAT III 1000V panel?

Yes, the TM-87 is rated CAT IV 600V and CAT III 1000V, so it is approved for measurements on that older panel.

How can I confirm the TM-87 is operating correctly after power-up?

Select a known voltage source within the 1000V DC range, verify the LCD shows a stable reading with the backlit display active, and check that the analog bargraph responds smoothly.
