Operation of the 24-7 Nutrient Monitor
IMPORTANT INFORMATION
•
Remove the rubber protectors from the pH
electrode's BNG connector before attaching it
to the 24-7 meter.
•
The PPM electrode uses a DIN connector. Find the guide
notch on the PPM electrode's DIN connector match it to the
DIN connector on the 24-7 meter. This will line up the holes
and the pins for easy insertion. Insert and screw the DIN connectors together using the connec-
tor ring.
•
You have purchased a scientific instrument requiring a delicate touch when calibrating. Read
both calibration and troubleshooting sections to familiarize yourself with the meter's operation
before calibrating. Be gentle; do not force the calibration screws past their stop. They are
sensitive and have less than 1 turn total travel. Hold the screwdriver between thumb and index
finger to turn the calibration screws. Take care in turning them as the screwdriver slots can be
stripped if pressure is applied to the screws after their maximum travel has been reached. The
warranty will be void if any calibration screw is stripped or damaged in any way.

- Page 3 Replace the electrode shield and dip the electrode into CWP Instruments 1382 PPM/2.7 EC (500 PPM to 1 EC). Swish back and forth to dislodge air bubbles. When the display stabilizes, gently adjust the PPM calibration screw to make the display read 138 PPM.
