3.5 Upkeep and Maintenance
We highly recommend that ECO meters be returned to the factory annually for cleaning,
calibration and standard maintenance. Contact WET Labs or visit our website for details on
returning meters and shipping.
After each cast or exposure of the instrument to natural water, flush with clean fresh water,
paying careful attention to the sensor face. Use soapy water to cut any grease or oil
accumulation. Gently wipe clean with a soft cloth. The sensor face is composed of ABS
plastic and optical epoxy and can easily be damaged or scratched.
WARNING!
Do not use acetone or other solvents to clean the sensor.
3.5.1 Bio-wiper ™ and Faceplate Cleaning and Maintenance
The bio-wiper ™ and the copper faceplate need to be removed from the meter for thorough
cleaning to maximize anti-fouling capability.
1. Be sure the meter is
NOT
powered or connected to a power source prior to
uninstalling the bio-wiper ™ and faceplate.
WARNING!
Manually turning the motor shaft can damage the wiper motor and will void the warranty.
Make sure the bio-wiper ™ is loosened from the shaft before attempting to rotate
the bio-wiper ™.
2.
Remove bio-wiper ™: Use the factory-supplied 3/32-in. hex key to loosen the screw
that secures the wiper to the shaft on the instrument. It may be necessary to remove the
screw from the clamping hole and screw it into the releasing hole, tightening it just
enough to free the
bio-wiper ™ from the shaft.

WARNING!
Be sure to retain and re-use the factory-installed screws as they are vented for
pressure compensation.
3. Remove faceplate: Use a small Phillips screwdriver to remove the screws that attach
the plate to the optics head.
