Frequently Asked Questions - UT-CS09C Uni-T

How do I switch between measurement units?

Press the UNIT button repeatedly to cycle through m, ft, in, inch, and ft+in. The selected unit appears on the display.

What should I do if the laser does not turn on?

Check that the batteries are inserted correctly with the correct polarity. Replace them if needed. Also ensure the power lock is not engaged.

How accurate is the UT-CS09C?

The specified accuracy is ± 2.0 mm under favorable conditions. Accuracy may be affected by ambient light, target reflectivity, and surface texture.

Can I measure from a corner or edge?

Yes, use the reference point function (press the REF button) to toggle between measuring from the front or rear edge of the device.

How do I retrieve stored measurements?

Press the MEM button to enter memory mode. Use the +/- buttons to browse through stored values. Press MEM again to exit.

What type of battery does the device use?

It uses 2× AAA alkaline batteries (1.5 V). For longer life, you can use lithium or rechargeable Ni-MH AAA batteries.

Is the device waterproof?

The UT-CS09C has an IP54 rating, meaning it is splash-proof and dust-resistant. Do not submerge in water.

How do I clean the lenses?

Use a soft, dry cotton cloth to gently wipe the laser lens and display. Do not use solvents or abrasive cleaners.

Why does the reading show 'Error'?

An 'Error' can occur if the laser is pointed at a reflective surface, if the distance is out of range (> 60 m), or if the target is too close (< 0.05 m). Try aiming at a matte surface.

Can the device be calibrated?

The UT-CS09C is factory calibrated. If you suspect accuracy issues, contact Uni-T support or an authorized service center. Do not attempt to open or adjust the device yourself.
