Description
KMR260 hand-held meter is easy to use and designed for demanding environment. The device is
housed in a durable and splash-proof metal case that is also hygienic and easily to keep clean.
KMR260 has a detachable connector for temperature sensor that enables changing sensors
quickly and easily according to the measurement target. The display is a clear and bright OLED
display that is also viewable in dark. In typical use the battery life of the internal Lithium-polymer
battery is over two weeks.
To each measurement result the following additional information can be saved: date, time,
measurer, measuring point and measuring target. Additionally high and low alarm levels can be
defined to each target. Measurement results are sent via radio to computer running PromoLog
data acquisition software.
Measured data is transmitted using license free 433.92 MHz frequency band (ISM)
so KMR260 can be freely used, for example, almost in whole Europe.

Measuring mode
Change to measuring mode from the normal mode by pressing the Measure button. In measuring
mode the current reading and a bar display is shown. The bar display indicates visually when the
temperature is suffi ciently stabilized.
On the left-hand side picture the reading is still changing and therefore the bar is only partially full.
On the right-hand side picture the reading is stabilized and bar is nearly full. Also the Ready and
OK buttons can now be used to send and save the measurement.
High and low limits can be set to measuring targets using PromoLog data acquisition software.
If the limits are set and the reading is within the limit values, a happy face is shown in the screen
after the reading. Respectively, a sad face with arrow pointing up or down is shown if a limit is
exceeded.
When the reading is sent via radio the text sending data and an antenna icon is shown on the
screen. When the data is sent the device returns to normal operation mode.
KMR260 always saves the measurement data to its internal memory. The internal memory has
space for over one thousand measurement results.This is useful in the case where the hand-held
meter is used outside the coverage area of a radio receiver. The data from the internal memory is
automatically transferred to PromoLog when the device is connected to a computer using a USB
cable.
