Zero Module
The Zero Module (PN 801690) allows for automatic re-zeroing of the
D
USTTRAK™ Instrument during long sampling runs. The Zero Module
works only with the 8530 and 8531 desktop models.
The AutoZero module is attached to the main instrument in two steps. The
first step is to place the Zero module over the instrument’s inlet and press
down. The Zero module has an O-ring seal that will engage with the
instrument’s inlet.

The second step is attaching the cable from the Zero module to the Zero
module connector located on the back of the instrument.
