i-STAT’s electronic simulator (both the internal and external versions) check
the amperometric and conductivity circuitry used in the coagulation tests at
multiple levels. The instrument checks the accuracy of the measurement of
elapsed time each time a test is run by comparing the clock rates from two
independent clocking circuits. The instrument also runs a battery of general
instrument checks during each test.
