Set Mode - Extech Instruments SD750 User Manual

Set Mode
Before taking measurements and datalogging, the SD750 must be configured to match the
application and transducers in question. The SET mode is used to accomplish the following:
o Format a SD memory card
o Set the clock date and time
o Set the sampling time (datalogging capture rate)
o Set the beeper sound ON/OFF
o Set the meter to use a decimal (US) or a comma (EU) for readings stored on the SD card
o Set the RS232 data output stream ON/OFF
o Set CH1, CH2, and CH3 pressure sensor parameters to match the transducer(s) being used
o Set the Pressure unit of measure (all channels use the same unit of measure)
Note: The datalogger function must be switched OFF before attempting to enter SET mode.
