tion and skip to the next parameter in the menu.
7.8.1 Sample Period
The sample period is the next parameter in the serial interface parameter menu.
The sample period is the time period in seconds between temperature measure-
ments transmitted from the serial interface. If the sample rate is set to 5, the in-
strument transmits the current measurement over the serial interface
approximately every five seconds. The automatic sampling is disabled with a
sample period of 0. The sample period is indicated by,

7.8.1.1 Duplex Mode
The next parameter is the duplex mode. The duplex mode may be set to full du-
plex or half duplex. With full duplex any commands received by the calibrator
via the serial interface are immediately echoed or transmitted back to the device
of origin. With half duplex the commands are executed but not echoed. The du-
plex mode parameter is indicated by,
