Routine maintenance

Profile Probe User Manual 3.0a
Keep your PR2 in its protection tube and fit the
connector cap when the probe is not in use. The Profile
Probe should be stored in a dry environment (definitely
non-condensing), and protected from sharp blows
Earth yourself on the metal connector before touching
the detector rings to avoid any possibility of damage by
electrostatic discharge.
Don't lay the PR2 in a puddle because water may creep
under the rings – if you suspect this has happened warm
gently (< 50°C) for 24 hours.
Lay as much of the cable as possible along the
surface of the soil when taking a reading in order to
minimise any electrical interference with other equipment.
Periodically examine the o-rings and centring springs
They should be kept clean, and if they show any signs of
damage, replace them. Pay attention particularly to the
lowest centring spring when inserting the PR2
access tube – a gentle twisting action helps.
The Profile Probe should be periodically recalibrated.
You should run a simple annual check on the calibration
(see the Troubleshooting section) and contact your local
Delta-T representative if there is a problem. Otherwise th
PR2 sh ould be returned for routine re-calibration every 5
years.
