Part 1 - Introduction
1.1 General
The Model Q45CT Portable Conductivity monitor/analyzer provides an extremely
versatile measurement system for monitoring and control of conductivity over the
range of 20 µS/cm to 2.000 Siemen/cm.
The system operates on two AA batteries, and will run continuously for
approximately 240 hours.
Warning: If unit is to be stored for more that 6 months REMOVE the
batteries from the holder to avoid potential damage from battery leakage.
The Q45CT portable displays conductivity and sensor temperature. The
instrument is used with the high performance toroidal sensors.

1.2 Features
•Standard Q45CT electronic transmitters are designed to be a fully isolated,
battery operated instrument. The monitor can be quickly converted to either a
loop power transmitter or line powered analyzer.
•Two 10-bit, isolated, 0-2.5 VDC analog outputs may be configured to track
conductivity and temperature. Both analog outputs can be individually
programmed to fail to specific values.
•Large, high contrast, custom Super-Twist display provides excellent readability.
The secondary line of display utilizes 5x7 dot matrix characters for clear
message display. Two of four measured parameters may be on the display
simultaneously. An LED backlight can be turned on if necessary for use in very
low light conditions.
•Sensor diagnostics monitor electrode coating/fouling, sensor leaks, and RTD
condition. Diagnostic messages provide a clear description of any problem with
no confusing error codes to look up. Messages are also included for diagnosing
calibration problems.
•Quick and easy one-point calibration method and sensor zero-cal. To provide
high accuracy, all calibration methods include stability monitors that check
temperature and main parameter stability before accepting data.
•High accuracy Pt1000 temperature input. Temperature element can be user
calibrated.
•Security lock feature to prevent unauthorized tampering with transmitter settings.
All settings can be viewed while locked, but they cannot be changed.

Part 2 –System Specifications
2.1 General
The Q45CT Portable Conductivity System comes complete with a specially
designed handle that allows the system to be comfortably carried, or quickly
strapped to a railing. Although the system is designed to be a portable system, it
can be permanently mounted for longer term field use. This is possible due to
the very long battery life spans that can be achieved with the system.
2.2 Portable Handle
A removable handle is included with each unit that provides not only comfortable
transportation of the system, but the integral locking strap allows the system to
be quickly mounted to pipes or rails for longer term use in one area.

Part 3 – Electrical Installation
3.1 General
The sensor cable can be quickly connected to the Q45 terminal strip by matching
the wire colors on the cable to the color designations on the label in the monitor.
Keep signal cable away from AC power lines, adjustable frequency drives,
motors, or other noisy electrical signal lines.
3.2 Direct Sensor Connection
The sensor cable should be routed into the enclosure through the right hand cord
grip on the bottom of the enclosure. Make sure the cord-grips are snugly
tightened after electrical connections have been made to prevent moisture
incursion. When stripping cables, leave adequate length for connections in the
transmitter enclosure, as shown below
.
