h) alarm function (HaL/LaL)

The measuring device has an alarm function to notify you when the measured value is not within the set tempera-
ture range. The alarm is acoustic (a beep) and visual (backlight flashes red). Thanks to this function, this measuring
device is ideal for monitoring. The alarm goes off when the set maximum value is exceeded (HAL) or when the
temperature falls below the set minimum value (LAL).
In the settings menu, press the "MODE" button (3) until function indicator (19) reads "HAL" or "LAL". Use the "UP"
button (2) and the "DOWN" button (8) to set the alarm values. The alarm goes off when the maximum value is ex-
ceeded (HAL) or when the temperature falls below the set minimum value (LAL). Put the "SET ALARM" switch (11)
in the battery compartment in the "ON" position to activate the alarm function.
If the set maximum value (HAL) is exceeded during an IR measurement, a beep is played and the background of
the display starts flashing red. The "HI alarm" symbol (24) flashes as well.
If the measured temperature falls below the set minimum value (LAL) during an IR measurement, a beep is played
and the background of the display starts flashing red. The "LOW alarm" symbol (24) flashes as well.

i) Contact temperature measurement (tk)

In addition to IR temperature measurement, IR 900-30S is equipped with a type K contact sensor for contact temper-
ature measurement. For contact measurements, connect a standard type K temperature sensor with a standardised
mini plug to the provided socket (4).
In the settings menu, press the "MODE" button (3) until the function indicator (19) reads "TK". The secondary display
(20) now displays the temperature value of the contact measurement.

j) measured data memory (Log)

IR 900-30S can save up to 20 measuring results. In the settings menu, press the "MODE" button (3) until the func-
tion indicator (19) reads "LOG".
Use the "UP" button (2) and the "DOWN" button (8) to select a memory position (1 - 20) to save an IR temperature
value.
Carry out an IR temperature measurement. After the measurement, the measured temperature (18) is displayed.
Press the "LASER / BACKLIGHT" button (6) to save the measured temperature at the selected memory position.
The temperature value is saved. Use the "UP" button (2) or the "DOWN" button (8) to select another memory posi-
tion.
To retrieve the saved temperature values, use the "UP" button (2) or the "DOWN" button (8) to select the memory
position you want to read. The saved temperature value is shown in the secondary display (20).
If all memory positions are used, you can overwrite any memory position as desired.
To delete all memory positions, hold down the measuring button (7) in LOG mode and select memory position
"0" using the "UP" button (2) or the "DOWN" button (8). Hold down the "LASER / BACKLIGHT" button (6) until
you hear a short beep. Now all memory positions are deleted.
