OfiTE 130-85 Instruction Manual - Maintenance
Maintenance
1. Always clean the cell immediately after making a measurement. Purge
the cell with distilled water until it is clear. If additional cleaning is nec-
essary, use a pipe cleaner and mild soap. Use no other solvents. Avoid
scratching the surface of the cell.
2. When it is no longer possible to calibrate the meter with the zero con-
trol, replace the 9-volt alkaline batteries (#147-02). Observe the polarity
markings on the printed circuit board.
3. If the mercury in the sample cell thermometer separates, it must be
reunited. First try shaking it down. If this does not reunite the mercury,
place the cell into hot water until the mercury just enters the top void.
Then remove the cell from the hot water and insert it into ice water to
pull the loose mercury into the graduated tube.
