2.1 Electronic Unit

The PAM electronic unit is battery operated. Its internal rechargeable battery is charged
automatically when external power is supplied to its miniature USB 'B' socket, either from a
PC or from a suitable USB power adapter. A fully charged battery will operate PAM
continually with its display at maximum brightness for approximately 16 hours.
When PAM is switched OFF, it goes into a standby mode in which it takes almost no current
from the battery although it still updates its internal calendar clock. PAM is switched ON by
pressing the ON/OFF button.
PAM uses the three buttons below the display as soft buttons whose functions change at
different stages of the PAM program. The lower line of PAM's 4 by 20 character display is
normally used to indicate the current function of each button.
When PAM is switched ON, the initial menu choice is between making measurements and
configuring the instrument to suit the user's specific requirements. The detailed menu
options will be discussed later.
As each PAM transducer has a built-in identification chip, PAM is able to interrogate each
transducer and adjust its own internal specification to match that of the transducer.
Prior to making any measurements, PAM automatically balances out any offsets using its
Autozero function.
Both gain and offset are adjusted automatically; the only operational requirement that the
user does not apply any force to the transducer during the Autozero process.
