LAL °F

NOTE

The high alarm setpoint does not change when the thermometer is turned off. However, when the batteries are replaced, it is reset to the default value as follows:

OS530HRE:250°F

OS530LE, OS532E, OS533E: 1000°F

OS534E:1600°F

OS523E:2500°F

OS524E:4500°F

•To set the low alarm value: (OS533E, OS534E, OS523E, OS524E):

1.Pull the trigger. Then press and hold the FUNC key until the Low Alarm Display Mode (LAL) appears.

2.Press the key to increment the low alarm value. Press the C F key to decrement the low alarm value.

3.Press the LOCK key to enable the low alarm function. The

icon appears.

If the temperature drops below the low alarm

setpoint, you will hear a beep and the icon on the display flashes.

4.To disable the low alarm, press the LOCK key again, and

the icon disappears.

NOTE

If you are not in Low Alarm Display Mode (LAL) when the low alarm goes off, you must press the

FUNC

key to get into the Low Alarm Display Mode.Then

press the LOCK key to		the low alarm.
		NOTE
		NOTE

The low alarm setpoint does not change when the thermometer is turned off. However, when the batteries are replaced, it is reset to the default value of -10°F (0° F for OS523E and 1000°F for OS524E).
