Dwyer Instruments TDS2-10 Installation And Operating Instructions

The Model TDS2-10 Cond./TDS Testing Pen monitors both conductivity and total
dissolved solids in streams, rivers, or any other body of water. It picks up impurities
and dissolved solids while checking the conductivity at the same time. This pocket
sized tester is constructed of a durable ABS plastic waterproof housing and 316
SS electrodes to protect against corrosion. A large LCD display is easy to read and
shows both the conductivity/total dissolved solids and temperature measurements
simultaneously. Since change in temperature can affect accuracy, the TDS2-10
has automatic temperature compensation. Batteries (four LR44 alkaline) included
in packaging.
OPERATING INSTRUCTIONS
Introduction
Please read the manual completely before using this meter. Filing and keeping the
manual for future reference is recommended. It is also recommended to soak the
electrode for at least 30 minutes before using the meter to clear anything affecting
the probe.
Power Supply
The meter is powered by 4 LR44 button cell batteries. Check the batteries if it is
your first time use, if the battery symbol appears on the LCD, or if the meter cannot
power on.
To install the batteries:
1. Turn off the meter.
2. Loosen the battery cover in the counterclockwise direction (DON'T discard the
black washer!).
3. Replace the old batteries with four new button cell LR44 batteries.
4. Make sure the batteries are in place and the polarity is correct.
5. Put the battery cover back and turn it tightly in the clockwise direction.
NOTICE Remove the batteries from instruments that you do not plan to
use for a month or more. Do not leave batteries in the
instrument.
