6.0 BASIC OPERATION
When first turned on the analyzer will act as a basic balance showing grams
weight on the display.
If a passcode has been set to limit access to the weighing functions of the
analyzer the display will show “PASSCODES”. The display will change to
show 7 digits set to zero with the rightmost digit flashing. Use the numeric
entry method (see section 4.1) to enter the code. Make sure to enter the
correct passcode to continue. See the Section 10.1.4 for details.
While in the weighing mode the test conditions for a drying test can be set.
6.1 SETUP
OF METHOD
The PMB analyzer is set to perform a drying test using a method determined
by the user. The drying method can be input from a number of different
sources.
• Using the keyboard
• Recalled from the internal memory of the analyzer
• Recalled from a memory stick plugged into the USB host connector
• Entered from a PC using the RS232 or USB interface.
Regardless of the method used it will be necessary to program the analyzer
with the following:
Type of test:
• % moisture =100 * ((initial mass - dry mass)/initial mass)
• % solid =100 * (dry mass/initial mass)
• % moisture vs. dry weight =100 * ((initial mass - dry mass)/dry mass)
Also called ATRO Moisture
• % solid vs. dry weight = 100 * (Initial mass/dry mass)
Also called ATRO Solid
ATRO Moisture or Solid test are special applications specific to some
industries. %Moisture and %Solid are the more common calculations.
