INTRODUCTION

Congratulations on your purchase of WT-40 water quality meter. A convenient
instrument to measure water pH, mV and temperature value.

FEATURES

• Automatic buffer recognition to avoid pH calibration error.
• Hold function to freeze the record.
• Max./Min. review of memorized data.
• Backlight for dark environment operation.
• Easy to view pH probe calibration data.
• USB connection for data download to a PC
• pH electrode with automatic temperature compensation.
• Auto power off to save battery power

OPERATION

Starting Up

1. Install batteries or connect with an adaptor to the power socket.
2. Connect pH electrode to the BNC port on the top of the meter. To
activate ATC, please also connect the temperature sensor plug to the
socket next to BNC.
3. Available parameters for pH probe are pH value, mV value &
Temperature.

pH/mV Measurement

WT-40 is designed to take reading with automatic or manual temperature
compensation. Automatic temperature
compensation only occurs when the temp.sensor is plugged. For manual
temperature compensation, the default setting is 25 oC. You can manually
adjust the temperature.
Be sure to remove the pH electrode soaker bottle before measurement. To
take the readings:
1. Rinse the probe with de-ionized or distilled water before use to remove
any impurities adhering to the probe. If the electrode is dehydrated, soak
it for 30 minutes in KCl solution.
2. Press "POWER" key to power on. "ATC" icon appears to indicate
automatic temp. compensation while the temp. probe is plugged.
