Keithley 740

System Scanning Thermometer

The Model 740 is a system scanning thermometer that can make tempatures measurements using seven different thermocouple types ( J, K, T, E, R, S, B) or millivolt measurements. With the use of the various thermocouple types, tempature mesurements in the range of -200 C to +1820 C can be made. A single intenal channel is standard equipment in the Model 740. The installation of a Model 7057A scanner card into the Model 740 expands the available measurements channels to nine. The measurement system is expandable to 81 channels with the addition of four Models 705s, or one Model 706 with eight scanner cards installed.

Some inportant Model 740 features include:

• Automatic scanning and data storage with HI/LO, of up to 81 channels.
• 20 channels per second scanning rate
• C or F tempature scale
• mV measurement capabilities
• 100 point single channel data logger with HI/LO/AVG
• 24 hour clock for time day and starting a scan or log
• Open thermocouple detection
• IEE Smart Print mode - talk to addressable as well as listen-only devices
• Digital calibration - no internal adjustments to be made
