  • Page 3: General Introduction

    GENERAL INTRODUCTION Thank you for selecting the 3011M meter. The 3011M is a precision tool that measure Conductivity, Salinity, TDS and temperature. A built-in microprocessor stores, calculates and compensates for all parameters related to Conductivity. This unit has a waterproof IP67 case. The touch mode keys are highly reliable with tactile and audio feedback.

  • Page 4: Installing The Batteries

    INSTALLING THE BATTERIES The 3011M meter is packaged with one 9 V battery required for operation. To insert the batteries into the meter, follow the procedure outlined below. Figure 1: Battery compartment 1. Use a screw driver to remove the four screws and battery cover to expose the battery compartment.
