YSI 9300 Photometer - Manual (Page 11)

8
Units
The photometer offers the choice of result expressed in mg/l, ppm, mmol/l,
µmol and g/l.
Sample Number (9500 Only)
A unique number may be associated with each result record to identify it in
the log. If Sample Number ‘On’ is selected, the user is offered the choice of
entering a number of up to 10 digits for each sample reading. If this function
is set to ‘Off’, a sample number is automatically allocated.
Sample Number Increment (9500 Only)
The sample number increment option may be used to determine whether the
instrument does or does not automatically increment the sample number after
each test. Incrementation of the sample number may be used when the
instrument is used for carrying out a series of similar tests. Alternatively it
may be preferable not to increment the number if typical use involves carrying
out a number of different tests on the same sample.
Dilution Factor (9500 Only)
When samples are out of range for the test, a dilution procedure may be
used. If the dilution factor option is set to ‘On’, the instrument will allow entry
of a numerical factor which will be used in the calculation of the result
displayed and stored in the log.
Date and Time (9500 Only)
The instrument records the date and time of each reading taken and
associates this with the data record in the log. To correct the date and time
on the internal clock, select the date and time display line.
Date Format (9500 Only)
The option of day/month/year or month/day/year date format is available.
Battery Level
A battery level indicator shows the power available. At least 3.0V is required
for successful operation of the instrument.
