On/Off Button; Battery Replacement - VWR 12777-838 Manual De Instrucciones

ON/OFF BUTTON

The ON/OFF button located on the back of the unit may be used to turn the unit off when the thermometer is
not being used. The minimum/maximum memory and alarm limits are not cleared when the unit is turned off.
To turn the unit off, press the ON/OFF button. Each successive press of the ON/OFF button will turn the unit
on or off.
No alarms will sound and no minimum/maximum memory will be recorded when the unit is off.
TROUBLESHOOTING
If this unit does not function properly for any reason, replace the battery with a new high-quality battery (see
the "Battery Replacement" section). Low battery power can occasionally cause any number of "apparent"
operational difficulties. Replacing the battery with a new fresh battery will solve most difficulties.
TRACEABLE® CERTIFICATE
To assure accuracy, the unit is supplied with an individually serial-numbered Traceable® Certificate provided
from an ISO/IEC 17025 calibration laboratory accredited by A2LA. The recommended recalibration date is
noted on the certificate that is included with the product. Annual recalibrations should occur thereafter.

BATTERY REPLACEMENT

Erratic readings, a faint display, no display, or a battery symbol appearing on the display are all indications
that the battery must be replaced. Open the battery compartment by depressing the tab located at the top of
the battery cover and lifting it out. The battery cover is hinged at the bottom so that the battery compartment
may be opened without completely removing the battery cover. Remove the exhausted battery and replace
with a AAA alkaline battery. Make certain to insert the new battery with the proper polarity as indicated in the
illustration in the battery compartment. Close the battery cover.
Replacing the battery has the same effect as pressing the RESET button. (See the "RESET BUTTON"
section.)
