LaMotte Tracer PockeTester Basics
The LaMotte meter has three measurements modes:
1) Conductivity
2) Total dissolved solids (TDS)
3) Salinity
You will need to cycle through the three modes when using the meter by pressing
and holding the MODE button. The ALLARM Shale Gas Volunteer Monitoring
Protocol uses the meter to test for conductivity and TDS.
Calibrate your meter at home every time before going streamside to monitor.
 If you monitor several sites in one day, calibrate the meter only once on that
day.
 If you monitor several sites over several days, calibrate the meter every day
before you monitor.
 When performing dual calibration, calibrate the low range first, keep the
meter on and then do the middle range. We recommend a dual calibration
for sites where conductivity is less than 500 µS/cm.
Step #1: Calibrate the Meter (home) option for single or dual calibration.
(A) Turn the meter on – press the ON/OFF button.
(B) Take the cap covering the electrodes off.
(C) Set the meter to conductivity mode – µS will be displayed above the reading
(see diagram for symbols). To change modes, press and hold the MODE
button until it switches modes (~3 seconds), then immediately release the
button. Repeat until µS is displayed on the screen.
Tip: If the meter enters the “hold” mode, press the mode button to exit.
(D) Shake the bottle of 84 µS/cm or 1413 µS/cm calibration solution and pour
~20 mL of solution into the calibration vial.
When doing dual calibration, you must start with low range 84
µS/cm, keep the meter on and then do the middle range 1413 µS/cm.
(E) Place the electrode into the solution, and allow the reading to stabilize.
This may take up to two minutes.
(F) Once the reading is stable, press and hold the CAL button for ~2 seconds,
until CAL appears on the bottom of the screen and 84 or 1413 flashes. When
the meter has been calibrated, SA and End will briefly flash and the meter
will return to the conductivity measurement mode. SA will not flash if the
calibration fails.
(G) Rinse the electrode with distilled water, shake dry, and turn the meter off.
(H) Make a note on your data sheet that you calibrated your meter – step #4 on
the ALLARM Chemical and Stage Monitoring Data Sheet.

Step #2: Measure Conductivity (stream-side)
(A) Turn the meter on – press the ON/OFF button.
(B) Take the cap covering the electrodes off.
(C) Set the meter to conductivity mode – µS will be displayed above the reading
(see diagram for symbols). To change modes, press and hold the MODE
button until it switches modes (~3 seconds), then immediately release the
button. Repeat until µS is displayed on the screen.
(D) Place the electrode into the water so that it is fully covered – either directly
into the stream or your stream testing bottle. Allow the reading to stabilize,
this may take up to two minutes.
(E) Record the conductivity measurement on your data sheet.

Step #3: Measure Total Dissolved Solids (stream-side)
(A) Without removing the meter from the water, change the meter to total dissolved solids mode. Press
and hold the MODE button for ~3 seconds – TDS will flash on the bottom of the screen and PPm will
be displayed above the reading.
(B) Allow the reading to stabilize.
(C) Record the total dissolved solids measurement on your data sheet.
Step #4: Replicates & Wrap-up (stream-side)
(A) Repeat steps #2 and #3 to measure the second replicates for each parameter.
(B) Press and hold the MODE button to switch from TDS to salinity.
(C) Press and hold the MODE button to change from salinity to conductivity mode (µS will be displayed
above the reading).
(D) Record the second conductivity and TDS results on your data sheet.
(E) Average the two replicates for each parameter and record the average value on your data sheet.
(F) Rinse the meter with distilled water, shake dry, and turn the meter off – press the ON/OFF button.
Troubleshooting the LaMotte Tracer PockeTester
If you are having difficulties calibrating or using your meter, try the following options:
Reset the meter
1. Turn the meter off.
2. Simultaneously press the
ON/OFF, CAL, and MODE buttons
momentarily. “dFlt” will be
displayed on the screen.
Replace the batteries
The batteries in the PockeTester will need to be replaced every 2-5 years,
depending on use. There is a low battery indicator on the meter that displays
“BAT” when the batteries become weak. You can find replacement batteries
(CR2032) at any local box/grocery/home improvement store or online. Four
new batteries cost ~$2. To replace batteries: turn off the meter, open the
battery compartment cap, remove battery carrier by pulling on the two black
plastic outer tabs on the battery carrier. Observe polarity of batteries (a
diagram is located on the side of the battery carrier) and replace batteries,
then replace battery carrier and battery compartment cap.
For additional help troubleshooting your meter, contact ALLARM.
