accidental change in the volume
during pipe ng.
For this pipe e the delivery volume of
liquid is set using the digital display. A
pointer is used to set exact or
intermediate volumes using the scale
on the last wheel of digital display
(refer point # 4.6)
The Locking mechanism ensures that the volume adjustment
knob remains at the setpoint while aspira ng or dispensing sample
liquids. Any effort to rotate the volume adjustment knob with the
locking mechanism engaged will damage the locking mechanism
and void the warranty.
5.2 SETTING THE VOLUME
•
To set the volume turn the volume lock lever to the “unlock”
posi on so that the volume can be adjusted to the desired
setpoint within the permi ed volume range. Refer following
images
•
A er pipe ng acids or other corrosive liquids that emit vapors,
remove the p-cone and rinse the piston, O-ring and seal with
dis lled water.
•
Do not pipe e liquids having temperatures above 70°C. (Not
recommendable)
•
Make sure that liquids never enter the p-cone. To prevent
this:
Avoid laying the pipe e horizontally when p is filled with
sample. As liquid may enter in and contaminate the sample
during next pipe ng cycle.
When there is liquid in the p, press and release the volume
adjustment knob slowly and smoothly.
Never turn the pipe e upside down.
•
Always store the pipe e without p on a shelf moun ng
stand supplied with or a pipe e carousel stand.
•
Highly recommended to calibrate the pipe e once in every 3-
6 months (depending on the sensi vity of usage) for be er
performance. The calibra on must be carried by gravimetric
method in accordance of DIN ISO 8655-6.
