Connecting the Combination
TDS/Temperature Probe

1. Slide the BNC connector over the
receptacle on the meter. Make sure
the pin on the meter connector is in
the lower end of the slot.

2. Turn the outer ring on the BNC
connector until the pin slides to the upper end of the slot.

NOTE: If the temperature probe is not connected, the temperature reading (°C)
will default to 25 °C.

NOTE: Wet the probe for 10 minutes before performing the calibration
procedure or taking readings in order to saturate the probe surface and minimize
drift.

Turning the meter on

The ON/OFF key will turn the meter on. All of the LCD segments will be
displayed for a few seconds as the meter goes through a self-diagnostic test.
The meter will then switch to the TDS measurement mode.

Probe Care

A dry probe should be soaked for at least 10 minutes before use.

Never scratch the stainless steel portions with a hard surface.

Do not strike the probe against hard surfaces.

Keep the TDS probe clean. Rinse the probe with deionized water or tap
water before storing it. The probe may be cleaned by swishing it in a mild
detergent bath and then wiping it with soft tissue paper. The probe should
then be rinsed with tap water and then rinsed in deionized water. Clean
the probe with alcohol to remove oils, films or oxidation. Recalibrate the
meter after cleaning the probe.
