INTRODUCTION
Congratulations on your purchase of WT-60 Conductivity/TDS water quality
meter. Conductivity measurements are used extensively in many industries.
For example, conductivity measurements are used to monitor quality in public
water supplies, in hospitals, in boiler water and industries which depend on
water quality such as brewing. WT-60 is a convenient instrument to measure
water conductivity, TDS and temperature.

Features
• Dual display with ATC (°C / °F switchable)
• Data hold to freeze display
• Selectable conductivity to TDS conversion factor
• USB download capabilities
• Low battery indicator.
• Auto power off
• Maximum 5 calibration points
OPERATION
Conductivity Measurement
1. Select range:
Meter is defaulted at "auto-ranging" which determines and selects the
range and gives the greatest resolution and accuracy. Alternatively, you can
manually select by pressing MODE >2 seconds. 5 ranges for selection and
“rAn” (auto ranging). It cycles from 1 to 5 and get back to auto. (Fig. 1)
2. Automatic Temperature Compensation:
The meter is defaulted as ATC on. To disable ATC, refer to programming
setting P1.3 and P3.3 for manual temp. compensation.
3. ASetting correct temperature coefficient:
Factory default is 2.1% per C (temperature coefficient) and this provides
good results for most applications. Refer P3.1 if a different value is needed.
4. Select normalization temperature:
Factory default is 25 °C. Refer P3.2 if a different value is needed.

5. Rinse the probe with deionized or distilled water to remove any impurity
adhering to electrode body. If the electrode isn't used for a long time,
please soak probe for more than 8 hours to clear up the lazy effect of the
probe.
6. Dip the probe into the sample. Make sure no air bubbles are tapped on
the slot of the probe. To remove air bubbles, stir the probe mildly and
make sure the electrode tip is submerged.
7. Stir the probe gently to create a homogenous sample.
8. Take readings. When the reading is stable, "READY" will display on the
left-middle LCD.
TDS Measurement
1. Set a correct TDS conversion factor. Factory default is 0.50. Refer P1.1 if a
different value is needed. See Appendix A & B for more information.
2. Select range & ATC/manual TC per your application.
3. Take readings. Press "MODE" to switch to TDS mode and get the reading.
Auto power off
This meter will shut off automatically 20 minutes of inactivity. To disable the
auto power off, pressing "SET" + "HOLD" keys simultaneously while turning on
the meter until a "n" appeared on the screen and then release keys to return to
normal mode. (Fig.2)

Setup
The advanced setup mode lets you customize your meter.
4 types parameter are available.
P1.0: Meter configuration: (CoF)
P1.1:TDS factor(tdS)
P1.2: READY indicator:(rdy)
P1.3: ATC or Manual TC: (Atc)
P2.0: Unit :(Unt)
P2.1 select OC or OF:(t)
P2.2 select ppm or mg/L: (tdS)
P3.0: temperature parameters: (t)
P3.1: Temperature coefficient:(tCo)
P3.2: Normalization temperature:(nor)
P4.0: View calibration data (CAL)
P5.0: Electrode data:(ELE)
P7.0: Reset to factory default setting(rSt)
P1.0: Meter configuration: (CoF)
P1.1: TDS factor (tdS):
The dissolved salts increases conductivity but the effect varies from sal to
salt and is roughly linear in a given range for a given salt. The TDS
conversion factor is used to convert conductivity into TDS.
In P1.0, press ENTER to enter P1.1. Press again to see TDS factor ashes on
LCD (Fig.3). Press UP/DOWN to change the value from 0.40 to 1.00. The
default value is 0.50. Press ENTER to confirm and enter P1.2.
