1. Introduction
Thank you for selecting the Oakton® 35607-00 conductivity/TDS meter. Included
with your meter is an epoxy-body stainless steel probe with built-in temperature
sensor and cable, a built-in four position probe attachment and a built-in meter
stand.
Your meter includes electrode holders and batteries.
Please read this manual thoroughly before operating your meter.

2. Display and Keypad Functions
Display
The LCD has a primary and secondary display.
• The primary display shows the measured Conductivity or TDS reading.
• The secondary display shows the temperature of the reading in °C.
The display also shows error messages, keypad functions and program functions.

Keypad
The large membrane keypad makes the instrument easy to use. Each button, when
pressed, has a corresponding graphic indicator on the LCD.
ON/OFF ................Powers and shuts off the meter.
HOLD ....................Freezes the measured reading. To activate, press HOLD while in
measurement mode. To release, press HOLD again
MODE ....................Selects the measurement parameter: COND (Conductivity), TDS
(total dissolved solids) or TEMP .
CAL/MEAS ..........Toggles user between Calibration and Measurement mode.
ENTER/RANGE ..Confirms your values. Switches to manual ranging and can scroll
to your selected measurement range for conductivity or TDS

3. Preparation
Inserting the Batteries
Four AAA batteries are included with your meter.
1. Use a Phillips screwdriver to remove the two screws holding the battery cover.
See Figure below.
2. Lift meter stand to expose battery cover. Remove battery cover.
3. Insert batteries. Follow the diagram inside the cover for correct polarity.
4. Replace the battery cover into its original position using the two screws
removed earlier.

Connecting the Probe and Temperature Sensor
NOTE: Keep connector dry and clean. Do not touch connector with soiled hands.
1. Slide the BNC connector of the probe over the BNC connector socket on the
meter. Make sure the slots of the connector are in line with the posts of the
socket. Rotate and push the connector clockwise until it locks
See figure
2. To remove probe, push and rotate the connector counter clockwise . While
holding onto the metal part of the connector, pull probe away from the meter.
CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
Temperature Sensor
The temperature sensor uses a phono jack to connect with the socket on the meter.
Insert the jack into the socket as shown in figure

Attaching the Probe Holder to the Meter
1. Place the probe holder with the flange facing the slot on the meter.
See Figure
2. Gently slide the flange of the holder into the slot on the meter. Make sure the
holder is secured properly into the slot.
You can attach the probe holder in different positions.
See figure
This flexibility facilitates one-handed operation.
Inserting the Probe into the Probe Holder
One probe holder is included with your meter.
NOTE: Do not use excessive force when inserting probe into holder.
1. Insert the probe into the opening of the holder until the top housing of
the probe touches the top of the holder.
