Cyanide test procedure
Follow the steps to ‘SELECT CUSTOMER’ & ‘CONNECT DEVICE VIA BLUETOOTH’ before
proceeding (see page 12).
ZERO METER*
Press the button. The cursor will move across the display followed by 0.00 PPM. This will
indicate that the sample is ready for testing.
DIP STRIP & PRESS READ
Dip the CN–1 strip into the CELL, and immediately press . This starts the 30 Second
countdown timer. Because the strip is 8 mm wide, the strip will need to be angled to fi t in the
cell. Be sure that the test pad is fully submerged. During this time, move the strip in a gentle
back and forth motion (approx. 2 strokes/sec). Remove and discard the strip after ‘1’ on
the display disappears.* The cursor will move across the display, at this point have your
CN–2 strip ready to dip into the CELL.
When the 30 Second countdown starts, immediately dip the CN–2 strip into the CELL.
During this time, with the strip angled slightly, move the strip in a gentle back and forth motion
(approx. 2 strokes/sec). Remove and discard the strip after ‘1’ on the display disappears.
The meter will automatically start to count up to 600 seconds. At 600 seconds, the cursor will
move across the display while the meter prepares to measure the sample. Record the result
displayed. This result is automatically stored in CN MENU, and if using the eXact iDIp
®
app,
will be stored in the app’s ‘RESULTS’.
After testing, rinse CELL immediately and clean with the brush.
NOTE: The calibration of the meter is based on a water temperature between 20°C (68°F)
and 25°C (77°F). If temperature is below 20°C (68°F), your fi nal Cyanide value may read low.
