2.6 Backlight the Display
When used in dark locations, the display of the Portable Digital Thermometer can be illuminated
by pressing the LIGHT/OC button. The backlight will turn off automatically after approximately 30
seconds, or may be turned off manually by pressing the LIGHT/OC button a second time.
2.7 Disable the Auto-Shutoff
The Portable Digital Thermometer will normally turn itself off after 15 minutes. Pressing any of the
buttons will delay the automatic shutoff for another 15 minutes. The technician can disable this auto-off
feature by pressing the LIGHT/OC button three times within 5 seconds. The small º F (or º C if in Celsius
scale) at the right side of the display will blink on and off to indicate that the unit is in “ON CONTINUOUS”
mode and will not turn itself off. This function is useful for MIN/MAX data collection over extended time
periods.
NOTE
You may wish to use the optional AC power
adapter when in “ON CONTINUOUS” mode to
prevent possible data loss due to battery failure.
2.8 Battery Replacement
When the battery in the Portable Digital Thermometer needs to be replaced, the display will show “LO P”.
Replace the battery with a 9-volt alkaline or equivalent NEDA type 1604A battery.
