Meter maintenance

The STARTER 5000 series instruments do not require any maintenance other than occasional
wiping with a damp cloth.
Attention: Follow these safety precautions when cleaning the instrument

Disconnect the instrument from the power supply

Do not open the instrument

Do not allow liquids to enter the instrument
Attention: The housing is made of acrylonitrile butadiene styrene (ABS). This material is attacked
by some organic solvents, such as toluene, xylene and methyl ethyl ketone (MEK). Any spillage
should be immediately wiped off.
6.3

Electrode maintenance

Make sure the electrode is filled with electrolyte solution. Always store the electrode according to
the electrode instruction manual and do not allow it to dry out.
If the electrode response becomes sluggish or the slope is not good enough, try the following:
o
Soak the electrode in 0.1M HCl for more than 8 hours.
o
For fat or oil contaminant, degrease the membrane with cotton wool soaked in either
acetone or a soap solution.
After electrode treatment, a new calibration should be performed. If the electrode slope is still not
good, the electrode might need to be replaced.
