4. ECO SENSORS INC Portable Ozone Sensor EcoZone Model EZ 1X INSTRUCTIONS FOR USE Before you read further Be sure that the EZ 1X warms up for at least 15 minutes It is highly recommended to warm up the EZ 1X overnight if it has not been used for over a week or if it has been stored near chemicals GENERAL DESCRIPTION Ozone is easy to sense but measurement can be very counter intuitive and tricky The Eco Sensors EZ 1X makes ozone sensing and monitoring simple and inexpensive The instrument is not a primary standard and is sold for general monitoring rather than precise measurements It can be used outdoors for short periods at moderate temperatures OPERATION There is no off on switch To power up the instrument simply plug in the AC adapter 12 volts DC At least one bar on the display will light up The first green bar is the on pilot light any additional illuminated LED colors bars indicate ozone in the area The EZ 1X will require up to 3 minutes to change to a new reading when the ozone concentration changes or when the instrument has been moved from one place to another FOR AC OPERATION Put the switch in the AC Power amp Bat Chg position This is also the position for charging the batteries FOR BATTERY OPERATION Put the switch in the Battery position The instrument will have up to 7 hours of usage from fully charged batteries The batteries probably will have some charge when the instrument is delivered Rech

VDC 5 500 MA CTR SERVICE AND MAINTENANCE Please contact your distributor about service In emergencies the factory service number is 800 472 6626 and the e mail is sales ecosensors com We recommend that the instrument be maintained and recalibrated annually Factory service plans are available Sensor The sensor is the only components of the instrument that is likely to fail or to require checkups We recommend that the sensor be checked for satisfactory operation every three months or more often in environments that are dusty have high levels of chlorine or halogen compounds or where there is dust or water spray The sensor should be observed to see if it is responsive to changes in ozone level and if the ppm readings are reasonable This can be done with the Eco Sensors model OG 2 hand held ozone generator Indications that the sensor is deteriorating or has failed are e Its response is significantly lower e The ozone concentration readings seem too high and tend to get even higher e The instrument doesn t respond at all and or the bar graph does not go down to the green area after a brief warm up Some of these problems can be compensated for by circuit adjustments or simple maintenance Sensor replacement however requires an instrument technician and should be done by Eco Sensors or its authorized service representative The replacement sensor is the model SE 6A Batteries The batteries are rechargeab
6. arging fully discharged batteries will require 14 hours of AC operation overnight or about one hour of charging per 30 minutes of use When the batteries are low the first green bar on will start to get dim and it will begin to blink Operation of the instrument should be concluded as soon as possible at this point within a minute or so to be sure because the battery decline thereafter can be very rapid A first sign of too low batteries after the blinking starts is slower instrument response and higher readings RECHARGING THE BATTERIES Put the switch down in the Bat Chg position Warm up is required with a major purpose being to burn off trace chemicals that the sensor will absorb if it has been idle and not heated Recommended EZ 1X warm up times by either battery or AC adapter are Time Since Last Powered Warm up Time 1 minute 3 days 10 minutes 3 7 days 1 hour more than 1 week 24 hours Warm up will not be required if the instrument is left plugged into its AC adapter and the switch is in the AC Power amp Bat Chg position SENSOR NOTES e Sensor failure which is the major maintenance item of the EZ 1X is indicated by the instrument always reading high e Occasionally a mechanical shock to the Instrument will cause the reading to go to zero even in the presence of ozone After about 5 minutes the sensor will gradually recover FOR USE AROUND SMALL OZONE GENERATORS See reverse side of this instruction she
7. et DATA READOUT LED Display This is a ten segment bar graph or color bar display that reads 4 green segments three yellow segments and three red segments The first green segment serves as a pilot light to indicate that the instrument is receiving power and when blinking that there is a low battery condition The second green segment comes on at 02 ppm of ozone the first yellow at 05 ppm the first red at 1 ppm and the final red at over 14 ppm of ozone The calibration is BAR PPM of Ozone BAR PPM of Ozone 1st green on 2nd yellow 07 2nd green 02 3rd yellow 08 3rd green 03 1st red 10 Ath green 04 2nd red 2 1st yellow 05 3rd red 14 ACCURACY AND CALIBRATION The EZ 1X calibration is shown above and is marked on the front face of the instrument The instrument is most accurate in the 05 1 ppm range and should be within 20 Below 05 ppm the reading jumps significantly from bar to bar for example 50 from the 2nd green to the 3rd green and so the accuracy is correspondingly limited there The instrument will respond to NOx and its derivatives commonly found in outdoor air especially in the evening and to the fumes of strong acids and chlorine compounds Chlorine compound fumes around swimming pools during normal operation are not a problem SPECIFICATIONS Sensor Heated metal oxide semiconductor Range 02 14 ppm of ozone Response time 10 s of seconds to respond and somewhat longer to recover
8. le NiMH They should last several years For a replacement battery pack not available in stores contact your distributor or Eco Sensors AC Power Adapters AC adapters usually are burned out by power surges such as from lightning but the EZ 1X itself has protection against such surges Replacement adapters for North American usage can be ordered from your distributor or Eco Sensors Inc elsewhere suitable adapters can be purchased from local electronic stores Specifications are found in our Tech Note P 101 PRECAUTIONS e Allow atleast 15 minutes warm up and better an hour or more If the instrument hasn t been used for days or weeks an overnight warm up will be helpful to burn off any contaminants that may have been absorbed by the sensor Read all instructions in this manual Keep instrument dry Never let water or other liquids into the sensor Do not drop the instrument or subject it to continuous vibration Do not store or operate the instrument in high levels of dust Do not attempt to service the instrument yourself You are likely to break the sensor which will be expensive and time consuming to replace e Do not clean the instrument with cleaning chemicals or solvents Clean it with a damp cloth or with ArmorAll e Do not operate the instrument near heavy aerosols spray usage or where oxygen is being administered e The sensor element which is very small operates at a temperature of about 500 degrees C
