“Net TDS”
TM
Mode:
The “NET TDS”
Tm
mode is accessed when the
meter is in TDS mode, by pressing the mode button for three seconds. When
the mode button is released, a flashing TDS light indicates that “NET TDS”
Tm
is being displayed. “NET TDS”
Tm
is an extrapolation of data, designed
specifically for the pool industry to reflect the “TOTAL TDS” of a saltwater
pool less the Salinity. To return the reading to the normal TDS mode, press
the mode button for three seconds and release; the TDS light will be solid.

Temperature Modes:
Provides an accurate measurement of
water temperature; when the temperature light is solid, the meter reading
is in Fahrenheit. To change the reading to Celsius, when in temperature
mode hold the mode button for three seconds. If the unit is powered off,
the temperature reading will stay in the mode measured in its last use. The
SLTD 100 will accurately display the temperature at all readings from 32 to
140 degrees Fahrenheit (0 to 60 degrees Celsius).
To turn the meter off, press the power button for 2 seconds. To conserve
battery life, if the meter is left powered on, but you are done using it, the
system will remain active for 60 seconds and then automatically turn
off. Battery life on Duracell Coppertop batteries is estimated at 80 hours
of operation, although storage temperature and other factors can affect
longevity.
Toroidal Conductivity Maintenance
The SLTD 100 probe sensor needs minimal maintenance.
To clean the
sensor
, located in the black capsule at the top of the probe section of the
SLTD 100:
1. Under normal conditions, with the SLTD 100 powered off at the end of
the day, maintenance is accomplished with simple rinsing of the probe in tap
water. This can also be accomplished by swirling the probe in a bucket of
clean (tap) water.
2. If there is debris or buildup on the probe and/or in the sensor, rinse
with
warm water to remove any deposits. Soak the sensor in a container of hot
water for 1 hour, again making sure that the unit is powered off. Use a soft
bristled brush (such as a toothbrush) or Q tip, and hot soapy water to scrub
the entire probe sensor body. Do not use a brush that is abrasive or that can
scratch the interior of the toroid capsule.
3. The hand held enclosure should be carefully cleaned periodically with a
damp paper towel or sponge.
