Taking TDS Measurements
1. Remove the protective cap.
2. Turn the TDS meter on. The ON/OFF switch is located
on the panel.
3. Immerse the meter into the water/solution up to the
max. immersion level (2").
4. Lightly stir the meter to dislodge any air bubbles.
5. Wait until the display stabilizes. Once the reading
stabilizes (approx. 10 seconds), press the HOLD button
to view the reading out of the water.
6. If the meter displays a flashing 'x10' symbol, multiply
the reading by 10.
7. After usage, shake off any excess water from your
meter. Replace the cap.
Taking Temperature Measurements
1. Once the meter is on, the temperature function can be
used at any time, in or out of liquid.
2. Press the TEMP button. The display will switch to
temperature (in Celsius only).
3. To return to TDS mode, press the TEMP button.
Changing the Batteries
1. Remove the battery compartment.
2. Install new batteries (model 357A or L1154). Be sure
the batteries are properly aligned.
3. Replace the battery compartment. The meter will turn
on automatically.
Precautions
1. The meter is not water-tight. Do not dip the meter
beyond the water level limit. The warranty will be
voided if water enters the unit.
2. Do not store the meter in high temperatures or direct
sunlight. Damage to the unit caused by user error or
carelessness will void the warranty.
3. Do not attempt to open the housing or tinker with the
electronics of the unit. Any unauthorized work on the
unit will void the warranty.
4. Though durable, the TDS-3 is an electronic instrument
and should be treated with proper care and
maintenance.
