LOG
Each of the up to 12 thermocouples is scanned once every four seconds to once every
hour (settable). The current readings are displayed on the large liquid crystal display. Read-
ings 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 all
12 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 to
your computer. Software to permit a personal computer using WINDOWS
