Scheduling When Sample Is Insufficient; Calculation Of Measurement End Time (Bath Processing); Routine Sample; Control Sample/Calibration Sample - Hitachi 902 Service Manual

7.3.2 Scheduling when Sample Is Insufficient

(1) Outline
If insufficient sample alarm is issued three times in succession, channel registration is
stopped for the subsequent tests for the relevant sample and system error is issued for
empty cell. For alarm indicatiton, refer to the alarm specifications.
(2)

Routine Sample

If insufficient sample alarm is issued for three tests in succession, subsequent channel
registration is stopped.
(a) Channel registration is stopped for TS not yet channel-registered (waiting for
channel registration) for the same sample.
(b) Channel registration is not changed when already channel-registered for the same
sample.
(c) Sampling is made as scheduled when CH registration is made for other sample.
(d) The alarm "sample short" is added to the sample for which insufficient sample alarm
is issued.
(3)

Control Sample/Calibration Sample

Channel registration is not stopped even when insufficient sample alarm is issued for
three tests in succession.
(a) The alarm "sample short" is added to the sample for which insufficient sample alarm
is issued.
7.3.3 Calculation of Measurement End Time (batch processing)
(1) Outline
The expected analysis end time at scheduling timing is calculated and displayed on the
screen upon input of the START key from the standby status.
(2) Basis for Calculation
The analysis end time is calculated on the basis of (a) and (b) given below.
(a) Calculation conditions
The end time is calculated by taking the samples requested at input of the START
key as samples to be measured. Note that the expected time is calculated only in
sample ID mode, and neither displayed not calculated in host communication mode
and when there is no TS request.
MODE
With ID
Sample no.
