Alarm function (HAL/LAL):
The measuring device has an alarm function to notify you when the measured value is not within the set
temperature range. The alarm is acoustic (a beep) and visual (backlight flashes red). Thanks to this func-
tion, 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 maxi-
mum value is exceeded (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 back-
ground 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.
Contact temperature measurement (TK):
In addition to IR temperature measurement, IR 900-30S is equipped with a type K contact sensor for
contact temperature 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 secon-
dary display (20) now displays the temperature value of the contact measurement.
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 function 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 dis-
played. 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 position.
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).
