Blanks and Samples
Palintest photometers use a BLANK to set the
instrument and a SAMPLE to take the reading.
The blank setting is held in memory. It is not necessary
to reset the blank each time a reading is taken if the
water samples are similar and the conditions of use are
the same. The blank setting can be confirmed if
necessary by taking a test reading on the blank.
Taking a Reading
1 Press the ‘on/off’ button to start the unit.
2 Press the ‘menu’ button until the test you wish to
perform is indicated on the screen.
3 Insert your blank and press the ‘blank sample’
button.
4 An image displaying a blank cuvette will be displayed
on screen. When this is replaced by 0.00 the
instrument is finished blanking and ready to take a
reading.
5 Remove your blank and replace it with the sample.
Press the ‘Read Sample’ button to take a reading.
The result will be displayed on screen in mg/l N.
