When the trigger is released the reading is automatically held for 60 seconds and 'HOLD' is displayed,
after which the thermometer will shut down.
MEASUREMENT ZONE/TARGET DISTANCE - The measurement zone is proportional to the distance
the RayTemp is away from the target. The thermometer is equipped with a 50:1 lens. If the target is
1250 mm away, the measurement zone will be 25 mm across.
THERMOCOUPLE PROBE/SENSOR - To display the thermocouple probe temperature, press and hold
the Mode button until 'PRB' is displayed. If the thermocouple breaks or is not connected, in addition the
instrument will display 'noP'. The thermometer should only be used with thermocouple type K
nickel-chromium/nickel-aluminium probes or sensors that meet BS EN 60584:1996 standard and are
tted with a suitable miniature thermocouple plug.

the average reading, press the Mode button again until 'AVG' is displayed. Maximum and minimum,
differential and average readings will be reset when the instrument powers down.Max/min reading can
also be displayed whilst using the probe function. To view the 'MIN' reading, press and hold the °C/°F
button or to view the 'MAX' reading, press and hold the Lock button.
HIGH & LOW ALARMS - To access and set the high alarm, press the Mode button until 'HAL' is displayed.
To adjust the high alarm value, use the °C/°F and the Lock buttons. To access and set the low alarm,
press the Mode button until 'LAL' is displayed. To adjust the low alarm value, use the °C/°F and the Lock
buttons. An audible warning will sound and the 'HI' or 'LOW' icon will be displayed in the LCD when the
temperature measured is outside the high or low alarm parameters.
°C/°F - The °C/°F button toggles between celsius and fahrenheit measurements. Press and hold
the °C/°F button without depressing the trigger until the °C or °F scale changes. Please note: the
instrument’s default is to start up in °C.
LOCK FUNCTION - The Lock button temporarily disables the auto power off, and is used for continuous
monitoring of temperatures for up to 60 minutes. Press the Lock button without depressing the trigger
until the 'LOCK' icon is displayed in the LCD. The unit will now continuously measure temperature
without the need to depress the trigger. To turn off the lock function, press and hold the Lock button.
