Other suitable cleaning method:
• Steam clean the PVDF flat tape only.
Battery Replacement
Push the battery drawer in and up and then release. The battery
drawer should eject slightly, allowing it to be pulled out. Replace
the 9V alkaline battery.
Other General Tips:
1. The probe should be cleaned after each use.
2. Always use the grounding cable.
3. Do not drop probe: damage to probe tip may result.
4. If battery is weak, the start tone will not sound, and flashing
“green” light will be off. Replace the 9V alkaline battery.
5. Where possible, use a Solinst tape guide to protect the tape
from scraping on well casing.
6. Before storage, make sure the meter is turned off.
If the Interface Meter is going to be stored for longer than
two months, the 9V alkaline battery should be removed to
avoid potential leakage.
7. The meter can be checked by placing the probe in distilled
(non-conductive) water or pure phase product, for example
lamp oil (
avoid bright sunlight during testing and resting
the probe on the bottom of the container
). A steady
tone and light should be observed.
8. To maintain Intrinsic Safety Certifications, do not splice the
tape.
6. The water/product interface should then be measured
as the probe is raised very slowly back up. Once the
interface is detected the probe can be raised and
lowered in small increments to precisely determine
the interface.
7. Repeat measurements to confirm water/product interface.
8. To determine the thickness of product, subtract the water/
product interface from the product/air interface.
9. To determine if there is any sinking product (DNAPL) in the
well, continue lowering the probe slowly. If steady signals
activate, determine the top of the sinking layer by reading
directly from the PVDF flat tape. Continue lowering the
probe slowly until the tape slackens when the well bottom
is reached. Read the level directly from the PVDF flat tape
and subtract one from the other to determine thickness.
10. Upon completion of readings clean the tape and probe; as
described in the Cleaning and Maintenance section
.
Cleaning and Maintenance
After each use, the laser-marked PVDF tape should be wiped
clean and carefully rewound onto the reel.
The probe should be cleaned as follows:
• Wash probe thoroughly with a non-abrasive mild detergent.
DO NOT USE ANY SOLVENTS
. Use a soft cloth around
the pins on the end of the probe to remove all product. Use
the brush provided to remove all product from inner part
of the probe.
USE LUKE-WARM, NOT HOT WATER. DAMAGE TO
THE PROBE MAY RESULT.
• Rinse probe thoroughly with distilled water, wipe dry.
• Return the probe to the holder.
Note:
In rare circumstances it is possible that the 122 might
sound when directed toward sunlight, and not in a
liquid. This is normal and does not affect proper
operation in a monitoring well.
Troubleshooting
Instrument will not turn ‘ON’
(no starting tone)
1. Replace the battery
2. Check the polarity of the battery in the drawer: make sure
the + and - on the battery and the drawer match. The
probe may be harmed by a reversed battery.
3. ON/OFF button could be faulty. Contact Solinst.
When instrument is turned ‘ON’, it immediately
sounds product tone or intermittent water tone
1. Probe sensor may be dirty. Clean according to Cleaning
and Maintenance instructions.
2. Water may have leaked into the probe. Carefully, remove
the probe, keeping the wires connected. Dry out the
probe, wipe and inspect the o-ring, replace if necessary
and/or lubricate with silicone. To avoid any nicks, make
sure the wires are tucked back into the probe body when
replacing the probe. See Probe Replacement Instructions.
3. Tape may be damaged. Clean the tape and look for any
cuts or nicks. If necessary, replace the damaged tape. To
maintain the 122 Intrinsic Safety rating, do not splice or
repair a damaged tape. Contact Solinst for assistance.
4. The reel or probe circuitry could be damaged.
Please contact Solinst.
Instrument does not detect liquid
1. Check battery. Replace if necessary.
2. Clean probe tip following the Cleaning and Maintenance
instructions.
3. Probe may be damaged. Please contact Solinst.
Instrument detects “Product” as “Water”
1. Note that this can happen if the probe is pulled into
product too quickly and therefore pulls water in with it.
Thoroughly dry the probe tip or shake the probe and try
again at a slower speed.
2. Product may have degraded or is now disturbed enough
to become an emulsion. If it has a detectable level of
conductivity, it will read water. Wait for it to settle and try
again.
Instrument does not detect water
1. Clean the probe tip. Follow the Cleaning and Maintenance
instructions.
2. The water could be pure and non-conductive or product
may be coating the probe, in which case, shake the probe
for a while in the water column to clean product from the
probe.
3. The probe circuitry could be damaged due to high
voltage (static) in the well. Always use a ground cable.
Please contact Solinst.
