Chapter I
Introduction
Thank you for purchasing the Russell RL060C portable conductivity meter. These
economy microprocessor-based handheld meters deliver up to ± 1% full-scale
accuracy. It has a large custom LCD (Liquid Crystal Display) for clear and easy reading.
The RL060C measures conductivity (μS/mS) and temperature (°C). This sturdy meter
measures up to 5 different ranges with auto-ranging capability that switches to
appropriate measuring range automatically.
Your meter includes a conductivity electrode (cell constant K = 1.0) with built-in
temperature sensor (Cat. No. 014005), 4 alkaline AAA batteries, user guide and
warranty card.
Please read this user guide thoroughly before operating your meter.
To order other accessories and calibration standard solutions, please refer to the
Ordering Information section for more information.

Display & Keypad Functions
Display
The meter has a large custom LCD that consists of 4-digit segments and operation
annunciators for µS/mS and °C (temperature). Other annunciators include “HO”
(when the HOLD function is activated) and “LO” (low battery condition).
See Figure 2 below.
LCD and Customized Annunciators for RL060C meter
1. Primary display
2. mS/cm (milli-Siemens/cm) or
μS/cm (micro-Siemens/cm) indicator.
3. Temperature indicator
4. Percentage indicator for temperature coefficient.
5. Low battery indicator.
6. Hold (frozen) reading indicator.

Keypad
The conductivity meter has 6 keys on its splash-proof keypad; , , , ,
and . Some buttons have several functions depending on its mode of
operation.
• Powers on and shuts off the meter. Takes
you directly into measurement mode when
meter is switched on.
•
•
Enters into calibration mode for
conductivity and temperature.
To abort calibration or setup mode without
confirming any set value.
•
•
HOLD: Freezes the measured reading. To
activate, press while in measurement
mode. To release, press again.
ENTER: Press to confirm values in
calibration mode, and to confirm selections
in setup mode.
•
•
•
In calibration mode: Press to scroll through
calibration values.
In setup mode: Press to scroll through the
setup sub-group programs.
Press during conductivity measurement
mode to activate manual ranging function.
Each key press will move up higher
conductivity range.
•
•
Selects measurement mode for
conductivity and temperature.
When pressed together with , it will
take you into the setup mode. This allows
you to customize meter preferences such
as selecting an electrode’s cell constant,
normalization temperature, temperature
coefficient factor, automatic (only
conductivity) or manual calibration, single-
point or multi-point calibrations, and to
reset meter to factory default.

Preparation
Inserting & Removing Rubber Armor
(Armor on Cat. No. 5124002 only)
1. To remove the meter from rubber armor, push the
bottom edges of the meter out until it is completely
separated from the armor. Ensure that the cables of
conductivity electrode or temperature probe are not
connected.
2. To insert meter into rubber armor, slide in from
the top of meter before pushing the bottom edges
down and set it into position. Lift up the stand at
the back of the meter for bench top applications if
necessary.

Inserting the Batteries
The battery compartment is found at the back
of instrument as shown. To open the battery
compartment, push in the direction of the arrow
and lift up the cover. Note the polarity of the battery
before inserting it into position. Place the cover back
and press down until it locks tight.
Battery Replacement
A “LO” annunciator in the LCD alerts you when
the battery power is running low. The replacement
batteries are 4 alkaline AAA.
Caution: Power off the meter when changing
battery.

Conductivity Electrode Information
The Russell RL060C hand-held meter is supplied with a conductivity electrode with
a BNC connector. This conductivity electrode (Cat. No. 014005) comes with stainless
steel rings, cell constant of K = 1.0, and a built-in temperature sensor for automatic
temperature compensation (ATC). Its specially designed Ultem-body housing has good
chemical resistant properties. It provides fast temperature response and reduces air
entrapment, which makes it easy to obtain accurate, stable readings.
The probe materials used which have good chemical durability include:
1. Polyetherimide (Ultem) – protective probe guard
2. Polybutylterphalate (Valox) – sensor housing
3. Stainless Steel (SS 304) – 2 steel bands
Proper use of the probe is essential to ensure that the optimum measurement is taken
in a short time.
The removable protective plastic probe guard is meant for simple periodic
maintenance and it must be kept intact during measurement and calibration.
Always immerse the probe beyond the upper steel band.
Note:
• DO NOT remove the protective probe guard during
measurement and calibration as it may affect your
readings.
• We recommend that you do not submerge
the probe above the protective guard. You can
submerge the cable for brief periods of time, but
not continuously.
See the Probe Care and Maintenance section for
more information.
