MAINTENANCE TIPS
The GT320 is not waterproof or water-resistant; avoid water, toxic
environments and temperature extremes.
Do not turn on the meter immediately after it has been taken from a
cold to a warm environment. The condensation that may result could
destroy the unit. Leave the meter switched off and wait until it reaches
room temperature.
Remove the battery when you do not expect to use the unit for a long
period of time (several months).
Clean the display by wiping it with a damp soft cloth. Never use
solvents or abrasives.
