CHAPTER 5
MAINTENANCE
5.1 Battery Installation
Under normal conditions, the battery will last up to a year of continuous
recording unless the logger is restarted very frequently.
In the OFF mode, the logger puts almost no load on the battery. Use the
OFF mode when the logger is not in use. Replace the battery once a year
in normal use.
If the logger will be used at temperatures below 32°F (0°C) or is frequently
turned on and off, replace the battery every six to nine months.
1. Make sure your logger is turned off (no blinking light) and all inputs
are disconnected.
2. Turn the logger upside down. Remove the four Phillips head screws
from the base plate, then take off the base plate.
3. Locate the two-wire (red/black) battery connector and attach the 9V
battery to it. Make sure that you observe polarity by lining up the
battery posts to the proper terminals on the connector.
4. Once the connector is plugged onto the battery, insert the battery
into the holding clip on the circuit board.
5. If the unit is not in record mode after installing the new battery, dis-
connect it and press the button twice then reinstall the battery.
6. Reattach the base plate using the four screws removed in Step 2.
Your logger is now recording (LED blinking). Press the PRESS button for
five seconds to stop the instrument.
NOTE: For long-term storage, remove the battery to prevent dis-
charge effects.
5.2 Cleaning
The body of the logger should be cleaned with a cloth moistened with
soapy water. Rinse with a cloth moistened with clean water. Do not use
solvent.
