OPERATING MANUAL12-Channel ScanningThermocouple ThermometerMENU FEXIT 0CLEARModel No.92000-00 Benchtop 115V92000-05 Benchtop 230VEach of the up to 12 thermocouples is scanned once every four seconds to once everyhour (settable). The current readings are displayed on the large liquid crystal display. Readings that exceed a maximum or minimum value can be set to trigger an alarm.Thermocouples of types: B, E, J, K, N, R, S or T can be used.Up to 4,680 data points can be logged (stored) within the unit, including readings from all12 channels and the date and time of the readings.The unit can be directly connected to a printer to provide a continuous printout, and/or toyour computer. Software to permit a personal computer using WINDOWS to store datafrom the unit, remotely operate the unit, and synchronize the operation of multiple unitsis included.Cole-Parmer Instrument Co.625 East Bunker CourtVernon Hills, Illinois U.S.A. 60061-1844(847) 549-7600(847) 247-2929 (fax)800-323-4340www.coleparmer.come-mail: techinfo@coleparmer.comA-1299-0763Edition 04 ColeParmerCP cover110/12/01, 10:59 AM

IntroductionSafety PrecautionsIntroductionThis Scanning Thermocouple Thermometer continuously monitorstemperatures at up to 12 locations. It is designed for laboratory orindustrial applications for unattended temperature monitoring. An alarm isset off when any thermometer exceeds its preset minimum or maximumtemperature. Temperature data is stored within the unit and can beoutput to a printer or PC.Safety PrecautionsDANGER:If thermocouples are at a high voltage, this voltage may bepresent at other points inside the instrument and outside atall the connectors.WARNING: Disconnect or turn off power source before makingconnections.WARNING: Turn power off and completely disconnect instrument.Disconnect power source, thermocouples, computer, links,and printer.WARNING: Other than a lithium battery, there are no user serviceableparts inside. Replacement of the lithium battery must beperformed per the Maintenance section of this OperatingManual. Refer servicing to your dealer.CAUTION: Be sure available power matches instrument power requirements.CAUTION: Protection provided by the unit may be impaired if the unit isinstalled and/or operated in a manner inconsistent withthese instructions.WINDOWS, WINDOWS NT - Reg TM Microsoft Corp.CENTRONICS - Reg TM Genicom CorporationTrademarks bearing the symbol in this publication areregistered in the U.S.A. and in other countries.1BA 1-12110/12/01, 11:01 AM

FeaturesInput Up to 12 thermocouple probes, each connected to a separate channel. Thermocouples can be different types. Thermocouples of types B, E, J, K, N, R, S or T can be used. Channels can be individually enabled or disabled.Data storage Up to 4,680 data records can be stored in the unit (a record includesreadings of all 12 channels plus time and date). Data can be logged (automatically stored). Current data can be manually stored by pushing the STORE button. Data is maintained even when the instrument is turned off or unplugged from power.Display Displays the thermocouple number and temperature as scanned. Operator can set the scan interval from a minimum of 4 seconds to amaximum of 1 hour. Readings can be stored and displayed in C, F, K, or R. Resolution to 0.1 can be displayed. Display can show: current, maximum, minimum, or average temperature. Average temperature display also displays the number of readingsbeing averaged. Hold function freezes all 12 channels.Data output All 12 channels can be output to a printer simultaneously. Current, stored, or logged data can be directly sent to a printer(CENTRONICS parallel). Time between printing cycles is adjustable. Current, stored, or logged data can be sent to a personal computer(PC)(RS-232 serial).Calibration Channels can be individually calibrated manually. Factory calibration remains in memory and can be restored at any time.Software Software (for a PC running WINDOWS 95/98 or WINDOWS NT) isincluded. Software use is optional. Software installation instructions and software manual are on theprovided CD-ROM. See readme.txt for latest information. Software permits control of up to 8 units. Real time data collection. Data can be input to spreadsheet or graphing software.4BA 1-12410/12/01, 11:01 AM
