93984 series thermometer is a non-contact infrared thermometer. Simply aim the thermometer at the target and press the ‘Scan’ button to display the surface temperature.

Laser Information:

By partially pressing the ‘Scan’ button, the device will begin to measure the temperature of the target. When the ‘Scan’ button is completely depressed, the laser will operate.

CAUTION!

1.NOT FOR FOOD SAFETY OR MEDICAL USE.

2.CONTAINS SMALL PARTS. KEEP OUT OF REACH OF CHILDREN.

°C OR °F MODE

To change from ‘°C’ to ‘°F’ or from ‘°F’ to ‘°C’, first turn the instrument on by pressing the ‘Scan’ button. Then press the ‘Mode’ button four times, the ‘°C’ or ‘°F’ symbol will flash. Press the ‘Scan’ button to change to scale, then press the ‘Scan’ button to confirm the mode.

MINIMUM OR MAXIMUM MODE

LCD ERROR MESSAGES

The thermometer incorporates visual diagnostic messages as follows:

「	」	‘Hi’ or ’Lo’ is displayed when the temperature being
		measured is outside of the range of the instrument,
		‘Hi’ when higher than +250°C (482°F) and ‘Lo’ when
「		lower than –33°C (-67°F).
	」
		‘Er2’ is displayed when the unit is exposed to rapid
		changes in the ambient temperature. ‘Er3’ is
「		」 displayed when the ambient temperature EXCEEDS
		0°C (32°F) OR +50°C (122°F). In both cases you
		should allow plenty of time (minimum 30 minutes) for
「	」 the unit stabilize to the working/room temperature.
		For all other error messages it is necessary to reset
		the unit. To reset it, turn the instrument off, remove
		the battery and wait for a minimum of one minute,
「	」 reinsert the battery and turn on. If the error message
		remains please contact the Service Department for

further assistance.

BATTERIES

The unit has two separate batteries. The battery closer to the side of the laser beam output is for laser operation only. The other battery is designated for temperature measurements. The unit can still measure temperature properly, even without the laser battery.

This item incorporates visual low battery indication (for the lower battery) as follows:

item should be stored at room temperature between -20 to +65°C (-4 to +149°F).

EMC/RFI

Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.

There are no user serviceable parts inside the instrument. Any attempted repair by unqualified persons voids the warranty.

To utilize the minimum or maximum mode: first turn the instrument on by pressing the ‘Scan’ button. Then press the ‘Mode’ button once for minimum or twice for maximum function. The ‘MIN’ or ‘MAX’ icon will flash, then press the ‘Scan’ button to confirm the minimum or maximum mode. The unit will display the minimum or maximum reading only.

LOCK MODE

The lock mode is particularly useful for continuous monitoring of temperatures.

To utilize the unit’s LOCK mode: first turn the instrument on by pressing the ‘Scan’ button, then press the ‘Mode’ button three times for the lock mode function. The lock icon will flash, then press the ‘Scan’ button to confirm the lock ‘Scan’ mode. It will continuously display the temperature for up to 60 minutes or until the ‘Scan’ button is pressed again.

BATTERY REPLACEMENT

When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with a CR2032 lithium cell. The battery is located under the twist cover at the rear of the thermometer. Please note: It is important to turn the instrument off before replacing the battery otherwise the unit may malfunction.

Dispose of used battery properly and keep away from children.
