microprocessor-based meters that deliver ±2% full scale accuracy.

Some of the features of these meters are:

• Large LCD for clear and easy reading

• CON 5 series meters allow measurement in Conductivity and Temperature (°C)

• TDS 5 series meters allow measurement in TDS and Temperature (°C)
This instruction manual is organized for easy reference. For basic functions of this

meter, read sections 2 through 5. These sections include basic instructions that will
get you up and running quickly. The remaining sections of this manual (6 through

12) deal with probe maintenance, error messages and troubleshooting. This part of

The Acorn has six keys on its splashproof keypad. These keys are ON/OFF,
HOLD/ENTER, CAL , ▲ (UP), ▼ (DOWN) and MODE.

ON/OFF: Powers meter on and shuts

unit off. Meter directly enters
measurement mode when you
turn it on.

CAL: Allows calibration of the meter

for Conductivity/ TDS and
Temperature

HOLD/ENTER: Freezes the measured

reading.; confirm calibration value
or option selected.

▲ (UP) / ▼ (DOWN): Scrolls up or

down to the values you want for
calibration.

MODE: Selects the parameter of

measurement: Conductivity/ TDS
or temperature.
