NORMAL OPERATION
1.
Press the ON/OFF Key to turn on the unit.
(No other button will activate the FW2000 / FW2000MK.)
2.
Select the temperature scale you wish to have the unit
display.
-- Press the F Key to display Fahrenheit readings or
-- Press the C Key to display Celsius readings.
3.
Insert probe into item to be tested.
Special notes:
• If the measured temperature is stable (doesn't change by
more than 3°F (2°C)) for 1-1/2 minutes, the unit will shut off
automatically.
• If the battery needs to be replaced, three blinking decimal points
( . . . ) appear on the LCD display. This means that 8 hours of
battery life remain. As battery voltage becomes less, "b.A.t."
will appear along with 3 blinking decimal points.
• If the unit gets a reading that is outside of its range
(-100° to 999°F )(-73° to 537°C), it will display either "HI" or "LO",
as appropriate.
• The unit has a "continuous on" feature. To activate, the unit
must be on. Hold down the Atkins Key and press and release
the ON/OFF Key. To deactivate, press the ON/OFF Key and
the unit will turn off.
CALIBRATION
To calibrate the unit, the temperature of the test solution you are
using must be 32°F (0°C) ± 5°F (±2°C) or must be greater than
60°F (16°C). For best results, use an ice bath which consists
almost entirely of crushed ice, with only a little water. Proceed as
follows:
1. Turn unit on.
2. Place the probe into the test solution.
3. Hold down both the F and C keys until "CAL" is displayed.
This takes approximately 3 seconds. You are now in
calibration mode.

CALIBRATION - Continued
4. Release both keys. "CAL" will be replaced by
the display.
5. Press and hold down the Atkins Key. "Hold" will be replaced
by three decimal points ( . . . ) with the current temperature
reading.
6. While holding the Atkins Key down, press the up or down
arrow keys (F or C) as appropriate. For example, if you are
using the ice bath method, and your reading is 35°F, press and
release the down arrow key as many times as needed until
"32F" displays on the LCD.
7. When you are done making adjustments, or if no
calibration is necessary, simply keep the Atkins Key
pressed until "End" displays on the LCD (approximately 7
seconds) and the unit returns to NORMAL mode. Release
the Atkins Key.
Special notes:
•
Failure to keep the Atkins Key pressed down at all times during
calibration will take you out of the mode and read "Abrt". To
correct this simply restart the calibration process from
Calibration step 1.
•
If the unit cannot be recalibrated by using the ice bath
method you can reset the unit to factory settings. To do so,
while in the CAL mode, still holding the Atkins Key, press both
the F and C keys for 3 seconds to select the factory defaults.
"FAC" will be displayed on the LCD for 2 seconds.
HOLD MODE
If "Hold" is displayed on the LCD when the unit is turned on, it
means an error has occurred. To correct this error, press the Atkins
Key. This will reset the unit to its previous calibration.
