LaMotte Tracer Salt Meter - Manual (Page 10)

TESTING
Getting Started
1. Remove the cap from the bottom of the TRACER to expose the pH
electrode, reference junction and the conductivity electrodes.
2. Before the first use or after storage, soak the electrode in tap water or
pH 4 buffer for 10 minutes.
3. White KCL crystals may be present in the cap or on the electrode.
This is to be expected if the TRACER has been stored for any
length of time. The crystals will dissolve with soaking or they can be
rinsed off with tap water.
4. Calibrate with pH 7 buffer prior to the first use or after prolonged
storage.
5. When the meter is calibrated for conductivity, salinity or TDS the
meter must be in the conductivity mode. See page 15.
Changing the Measurement Function
The meter can be set to measure Conductivity, pH, Salinity (ppm),
TDS(ppm), or TDS (mg/L). To change the mode:
1. Turn the TRACER on.
2. Press and hold the MODE/HOLD button for 2 seconds. The display
will begin to scroll through the units.
µS or mS (Conductivity)
pH
ppm S or ppt S (Salinity)
ppm or ppt (TDS)
mg/L (TDS)
NOTE: 1 part per thousand (ppt) equals 1000 parts per million (ppm).
Example: 3.1ppt=3,100 ppm
3. Release the MODE/HOLD key when the desired mode is displayed.
NOTE: The “HOLD” function can not be used when changing the
measurement function. If “HOLD” is displayed in the lower left corner
of the display, briefly press the MODE/HOLD button to turn it off.
