Part 1 - Introduction

1.1 General

The Model Q45D/60 is a highly versatile portable monitoring/recording system designed

for the measurement of dissolved oxygen in solution. The full scale operating range of

the system is 0-40.0 ppm and the sensing system will operate on water streams with

temperatures from 0 to 50



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 basic sensing element used in the dissolved oxygen monitor is a galvanic membrane

sensor which measures dissolved oxygen directly.

1.2 Features

Standard Q45P electronic transmitters are designed to be a fully isolated, battery

powered 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 pH and

temperature, or pH and pH. Both analog outputs can be individually programmed to

specific ranges.

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 back

light can be turned on if necessary for use in very low light conditions.

Sensor diagnostics monitor glass breakage, 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 two-point and sample calibration methods include auto-buffer recognition

from 3 built-in buffer tables. To provide high accuracy, all calibration methods include

stability monitors that check temperature and main parameter stability before accepting

data.

Selectable Pt1000 or Pt100 temperature inputs. Systems can also be hard-configured for

three-wire elements. 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 – Instrument Handle/Mounting

2.1 General

The Q45D/60 Portable Dissolved Oxygen System comes complete with a specially

designed handle that allows thesystem to be comfortably carried, or quicklystrapped to

arailing. Although the system is designedto be a portable system, it can be permanently

mounted for longer term fielduse. This is possible due to the very long battery lifespans

that can be achieved with the system.

2.2 PortableHandle

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 Connection

3.1 General

The sensor cable can be quickly connected to the Q45terminal strip by matching the wire

colors on the cableconductors. A junction box is also available to provide a quick-

disconnect point for the sensor, or a break point for very long sensor cable runs. Route

signal cable away from AC power lines, adjustable frequency drives, motors, or other

noisy electrical signal lines. Do not run sensor or signal cables in conduit that contains

AC power lines or motor leads.

3.2 DirectSensorConnection

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.
