5.5 Accessories
The 1522's accessories and their features are described here.
AC Adapt er - The ACadapter recharges the internal battery pack and may also
be used tosupply power to operate the 1522 while the battery is being charged
(see Section 6.2).
Serial Cable - The serial cableis used to connect a computer or a p rinterto the
1522 through its serial port (see Section 8).
INFO-CON Connector - Hart’sunique INFO-CON connector allows the
probe to be easily attached and detached. Itcontains a memory device that
storesinformation about the probe and automatically transfers this data to
the 1522 when the probeis attached. This ensures that the settings used to
measure and calculate temperature alwaysmatch the probe being used (see
Section 6.6).
Probe- The probe acts as the temperature sensor. Its resistance depends on its
temperature.The 1522 precisely measures the resistanceof the probe and uses
the coefficientsstored in the IN FO-CON connector to calculate its temperature
(see Section 6.5). The followingprobe options are available.
