IV. Maintenance and calibration
General
To keep the display panel and operator buttons free from dirt build-up, regularly
wipe over your Sprint unit with a slightly damp cloth.
4.1 Unit
The Sprint should be calibrated once a year. Your Sprint unit will also display
the calibration due date at switch on and will warn you when calibration due
date is drawing near. If the calibration due date has passed, the Sprint unit will
display a message 'Calibration overdue'.
4.2 Water trap
The combined filter and watertrap is used in-line between the probe and the
unit. Before performing any tests, check that the filter is clean and there is no
water inside the trap.
Filter
The filter element should be changed if the filter has
become contaminated or dirty. If the filter has become
soaked with water, remove from trap and leave to dry
before reusing. Ensure 'O' ring remains in place.
To change the filter
Unscrew the filter-housing, remove the old filter and replace.
Water
To empty the water trap, unscrew the filter-housing, remove the bung and
empty. Replace bung after emptying.
Warning: Filters
must be used at all
times. Failure to do
so may invalidate
the warranty.
