Ultrasonic Distance Measurer
OWNER’S MANUAL
PREPARATION
INSTALLING BATTERIES
Your measurer requires 9V battery (not supplied) for power. For the best
performance and life, we recommend alkaline battery.
Follow these steps to install a battery.
1. Slide the battery compartment cover in the direction of the arrow to remove it.
2. Snap the battery in the compartment, as indicated by the polarity symbols (+
and - ) marked inside.
3. Replace the cover.
When LOW BATT appears or the measurer stops operating properly, replace the
battery.
Caution: If you do not plan to use the measurer for a month or more, remove the
battery. Batteries can leak chemicals that can destroy electronic parts.
STABILIZING THE MEASURER
Your measurer is sensitive to changes in temperature and humidity. Before you
use the measurer, wait about 15~30 minutes for it to stabilize to the current
room’s temperature.
OPERATION
TURNING THE MEASURER ON/OFF
To turn on the measurer, press MEASURE. The measurer turns itself off if no key
is pressed within about 4 minutes or press MEASURE for 3 seconds to turn it off.
TAKING A MEASUREMENT
1. Press MEASURE to turn on the unit. The measurer beeps then the distance
between the measurer and the point you measured appears.
2. Hold the bottom of the measurer flat against a wall, about halfway between the
floor and ceiling. Be sure there is a clear path to the point you want to measure
and that your head or hands do not block the front of the measurer.
3. Repeatedly press FEET/METER until FEET appears (to measure in feet ) or
until METER appears (to measure in meter).
