Operation Instruction
NOTE: After abrupt ambient temperature changes, allow
meter at least 20 minutes to equilibrate to the new
ambient condition before taking measurements. This
allows ample time for the internal CJC to equilibrate to
the new ambient temperature.
Turning the Unit On and Off
Press the ON/OFF button momentarily to power the unit
on. Make sure that there is sufficient battery power.
Press and hold the ON/OFF button for 2 seconds to
power the unit off.
Enabling and Disabling the Auto-Off
To save battery power, the unit includes an Auto-Off
feature that automatically shuts the unit off after
approximately 20 minutes. The factory default setting is
Auto-Off disabled. To enable the Auto-Off function, press
and hold the Light button while powering the unit on. A
double beep sound will confirm that the Auto-Off is now
enabled. To disable the Auto-Off, press and hold the
Light button while powering the unit on. A single beep
sound will confirm that the Auto-Off is now disabled.
Max/Min Function
The TW8060 includes a Max/Min function. While the
unit is powered on, it will continuously record the
maximum and minimum recorded temperature. The
Max/Min temperatures will be stored until they are
cleared by the user, even if the power is shut off. To
view the Max/Min readings, press the Max/Min button
once to see the Max reading for both channels, then
again to see the Min reading for both channels, and one
more time to return to the main display.
To clear the Max/Min function, press and hold the Max/
Min button for 3 seconds. CLER will be displayed
momentarily.
NOTE: If the Max or Min display show OL, clear the
Max/Min function and continue. It is recommended to
clear/reset the Max/Min function after replacing probes.
Alarm On/Off
After the alarm high and low values are set the user can
turn the alarm function on or off. To turn the alarm
monitoring on press the ALARM ON/OFF button and the
word LIMIT will be displayed directly above the T1
temperature display. To turn the alarm monitoring off
press the ALARM ON/OFF button and the word LIMIT
will no longer be displayed.
NOTE: It is recommended to disable the Auto-Off
function prior to alarm monitoring as the unit will power
off after 20 minutes if the Auto-Off function is enabled.
See above for instructions.
NOTE: Alarm monitoring is for channel 1 only (T1).
Setting the Hi/Lo Alarm Limits
To set the alarm high and low monitoring temperatures
for channel 1 only, press the HI/LO button and the
current HI limit will be displayed. Press the UP and
DOWN buttons to set the desired temperature. Once the
desired HI limit temperature is set, press the HI/LO
button again to display the current LO limit setting.
Press the UP and DOWN buttons to set the desired
temperature. Once the LO limit setting is reached press
the HI/LO button to accept. To cancel at any time and
not store the HI/LO readings press the ALARM ON/OFF
button to return to the main display.
NOTE: To scroll up and down faster during the alarm
temperature setting, press and hold the UP and DOWN
buttons for a longer period of time.
NOTE: To reset the alarms to factory default settings,
press and hold the ALARM HI/LO button for 3 seconds.
CLER will be displayed momentarily.
Setting the Display Units
The TW8060 will display temperature in two scales,
Fahrenheit and Celsius. To switch from one scale to the
