RS-232 PC Interface
The Model 421508 Thermometer is supplied with a sophisticated Windows
TM
software
package on disk. A communications cable (meter to PC) is also supplied. The disk
contains program files, software instructions, and communication protocol; refer to the disk
for details.
The program allows the user to operate the meter remotely and view the readings from all
three LCD fields on the PC monitor. The software also permits measurement data to be
stored as text files on a PC. The data files can then be exported to spreadsheet or other
programs for further manipulation (graphing, sorting, filing, etc.).
Battery Replacement
Replace the battery when the low battery indication symbol appears on the upper left
corner of the display. To replace the battery, remove the two screws that secure the rear
battery compartment cover. Remove the old battery, install a new one, and replace cover
