Frequently Asked Questions - UT275 Uni-T

What is the maximum current the UT275 can measure?

The UT275 can measure AC current up to 1000A.

Can the UT275 measure DC current?

No, the UT275 measures AC current only via the clamp. For DC current, you need a model like UT273.

What battery does the UT275 use?

It uses a standard 9V battery (6F22 or NEDA 1604).

How do I replace the battery in the UT275?

Turn off the meter, remove the battery cover screw, lift the cover, replace the 9V battery, and reattach the cover.

Is the UT275 autoranging?

Yes, it has autoranging for voltage, resistance, capacitance, and frequency. You can also manually select ranges.

Does the UT275 have a backlight?

Yes, it has a backlight for working in low-light conditions.

What is the safety rating of the UT275?

It is rated CAT III 600V and CAT II 1000V.

Can I measure temperature with the UT275?

Only with an optional temperature probe (K-type thermocouple). It is not included by default.

How do I measure inrush current?

Press the INRUSH button (if available) or use the data hold feature to capture the peak value.

What is the warranty period for the UT275?

Uni-T typically offers a 1-year warranty against manufacturing defects. Check your local seller for details.

USER MANUAL UT275 Uni-T

UT278A+

UT270 series can quickly and safely measure the grounding system without disconnecting circuit ground lines or the need of auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω. UT275 can also measure leakage current up to 30A. These clamps' double insulation design makes them durable tools for outdoor work and effective in blocking interference from the environment.
