OPERATION

This section contains basic operating instructions, to

insure accurate results and for more advanced functions,

refer to the additional sections that follow.

1. Remove the protective cover from the probe head.

measure (conductivity or TDS).

4. Place the probe head into the solution to be measured.

5. To insure Automatic Temperature Compensation,

immerse the probe head and temperature sensor

completely. For accurate Automatic Temperature

Compensation, the temperature sensor must reach

equilibrium with the liquid being measured, this could

take several minutes.

6. Insure that there is adequate movement of the liquid

around the tip of the probe head (0.2 - 0.3 meters per

displayed in the alternate range, the meter will switch

ranges (see the “Range Mode Selection” section).

7. Take the desired measurements.

8. Press the

If no button is pressed for twenty (20) minutes, the meter

will turn off automatically to preserve battery life (see the

BATTERY REPLACEMENT

An erratic display, faint display, no display, or a battery

symbol appearing on the display are all indicators that

the batteries need replacement. The battery cover is

located at the top of the unit. Unscrew the battery cover

by turning it counter-clockwise. Remove the exhausted

batteries and replace them with four (4) new #357/LR44
