Maintenance

5.1

Meter maintenance

Never unscrew the two halves of the housing.
The SevenGo™ series instruments do not require any maintenance other than an occasional wipe with a
damp cloth and the replacement of dead batteries.
The housing is made of acrylonitrile butadiene styrene/polycarbonate (ABS/PC). This material is attacked
by some organic solvents, such as toluene, xylene and methyl ethyl ketone (MEK). Any spillage should be
immediately wiped off.
Note
To prevent static damage to the instrument, always disconnect the conductivity sensor from the meter before
cleaning the sensor.
