Page 5: Introduction
INTRODUCTION General Description The Z130 is a microprocessor controlled oxygen analyser based on a Zirconia oxygen sensor. It provides a range of features and a performance without parallel for an analyser of this type and cost. Standard features include auto-ranging over a span of 100% to 0.01ppm, user programmable alarm levels, hysteresis and analogue output. -

Page 8: Installation
INSTALLATION Unpacking and visual checking Take all normal precautions when opening packages. In particular, avoid the use of long bladed cutters. Check for any sign of damage. Check that all pipe connections have captive seal nuts - search packing if any are missing. Calibration overview The instrument should be installed where free air ventilation around the whole case is provided. -
Page 9: General Advice Sample
3.3.2 General advice Sample The instrument is supplied with one of several sample system types specified by the user on order. A label on the instrument shows the pressure limits and other data for the particular one fitted. This should be taken into account before applying a sample. WARNING The case should not be exposed to water jets or drips. -

Page 11: Switching On
Switching on When the analyser is fully connected it may be switched on. The cell heater will begin to warm up. During this time the display will flash “HE xxxxx and the concentration display will make high and low excursions. Once the correct temperature is reached, the “HR” will end and the display will stabilise. - Page 12 Figure 3 - 130 series menu INM MTL 130-0200 Rev 4...

Page 13: Calibration
CALIBRATION CAUTION Various procedures associated with calibration maintenance affect the outputs of the instrument. Any of these outputs that are being used for control (or the associated control loop) should be disabled before commencing. Calibration overview The Z130 is a very stable analyser with a drift rate of better than 2% of reading per month. How often the calibration is checked or verified depends on the quality regime being operated at the installation site. -

Page 15: Maintenance
MAINTENANCE Calibration is the only routine operation that is necessary on a regular basis. The Z130 is a very stable analyser with a drift rate of better than 2% of reading per month. How often the calibration is checked or verified depends on the quality regime being operated at the installation site. -
Page 16: Technical Description Of Sensor
TECHNICAL DESCRIPTION OF SENSOR The zirconia oxygen sensor (see sketch below) is an impervious tube-shaped zirconia (zirconium oxide) element with a closed end coated externally and internally with porous metal electrodes, typically platinum. At high temperatures, typically above 400°C, the zirconia becomes an oxygen ion conductor, which results in a voltage being generated between the electrodes dependent upon the differences between the partial pressures of the oxygen in the sample and the oxygen in a reference gas (generally air). -
Page 17: Communication Protocol
COMMUNICATION PROTOCOL Communication parameters are 9600 Baud, 8 bits, no parity, 1 stop bit and no handshaking. The instrument is DTE. The general form of the protocol is: The protocol is a single command and response protocol. 2. A command consists of an “address” and an “action” . A received valid address is always responded to even if the action is invalid. -
