INTRODUCTION

Thank you for purchasing WT-50 Dissolved Oxygen meter. The meter measures

DO concentration with temperature compensation, salinity and pressure

correction, which is an accurate instrument for water quality testing. The

handy size and extension probe enables on-site testing and the memory and

PC link function are also ideal for data collection and processing.

Features

• Accurate dissolved oxygen measurement

• Salinity and barometric pressure compensation

• 100% air saturation calibration

• 99 point memory

• Real time clock for data record

• USB interface for data transmission

OPERATION

1. Press "POWER/SET" to turn on and off the meter.

2. Press "MODE" to select DO scale between % and ppm (or mg/l).

3. Perform 100% air saturation calibration before measurement. (See page 7)

If the stable readings (15 minutes after power on) are within 100%+/-0.5%,

then no need to do the calibration.

4. Salinity and barometric pressure have effects on DO accuracy. The meter

default is 760mmHg in pressure and 0.0ppt in salinity. Correct salinity

value of water and barometric pressure in Setup P3.0 if the conditions of

measuring site are different.

5. Immerse the probe head in the liquid and it display DO concentration on the

LCD. Automatic Temperature Compensation takes several minutes to

equalize temperatures of the probe and liquid and get stable readings.

6. Press "HLD/REC" in measuring mode to hold the current readings. HLD icon

will be displayed on LCD. Press the button again to resume measuring.

7. Press "HLD/REC" and "MNX/AV" simultaneously to activate backlight.

It turns off automatically after 10 seconds.
