Introduction Safety Precautions Introduction This Scanning Thermocouple Thermometer continuously monitors temperatures at up to 12 locations. It is designed for laboratory or industrial applications for unattended temperature monitoring. An alarm is set off when any thermometer exceeds its preset minimum or maximum temperature. Temperature data is stored within the unit and can be output to a printer or PC.

Safety Precautions DANGER:

If thermocouples are at a high voltage, this voltage may be present at other points inside the instrument and outside at all the connectors.

WARNING: Disconnect or turn off power source before making connections. 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 serviceable parts inside. Replacement of the lithium battery must be performed per the Maintenance section of this Operating Manual. 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 is installed and/or operated in a manner inconsistent with these instructions.

Features Input • 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 includes readings 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 a maximum 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 readings being 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) is included. • Software use is optional. • Software installation instructions and software manual are on the provided 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.

A. Thermocouple connections • Connect up to twelve thermocouples here. • Jacks are for two blade mini-ANSI connectors. • Thermocouples of types B, E, J, K, N, R, S, or T can be used. See Appendix B for a description of thermocouple types. • Any combination of thermocouple types can be used at the same time. • If a thermocouple connection (channel) is not used it may be disabled using the Menu. See Menu - How to: Enable/Disable channels on page 30.

B. Power switch Toggle to l to turn power to the instrument on. Toggle to 0 to turn power to the instrument off. When power is turned on the display goes through a display check sequence: all display elements are turned on momentarily, then the 1,2,...12 icons (small numbers) turn off in sequence, and then the display switches to normal operation. An internal lithium battery maintains the real-time clock for power outages for over a year.
