American Marine PINPOINT II User manual

American Marine is proud to introduce the PINPOINT® Calcium
Monitor. The only truly affordable and accurate digital Calcium
measurement instrument designed exclusively for marine saltwater.
Powered by a 9-volt battery (not included). PINPOINT® Calcium
Monitor will operate for approximately 150 total hours before battery
replacement is indicated on the display.
NOTE: The Calcium Monitor unit is NOT waterproof and must be
operated on a dry surface. Liquid contact on the printed circuit board will
cause corrosion and void warranty.
•Probe Set-up
1)This probe is a solid state single piece, permanently filled model Ver III.
2)Remove the storage bottle that protects the probe tip by unscrewing
the bottle from the bottle cap. When not in use, probe should be stored in
the protective bottle without any fluid added to the bottle.
3) Be careful not to damage the flat PVC membrane on the probe tip.
This membrane should be kept as clean; free from algae, etc.
•Meter Set-up
1)All calibration fluids and tank water sample should be room
temperature for greatest accuracy.
2)Pour the 100 ppm Ca++ calibration fluid into a clean cup or storage
bottle.
3)Pour the 1,000 ppm Ca++ calibration fluid into a 2nd clean cup
4)Install a new 9-volt battery or the PINPOINT AC Adapter to the battery
compartment wires on the back of the meter.
5)Attach the BNC connector from the probe cable to the front of the
meter. Lock it into place with a 1/4 turn to the right.
•Calibration and Measurement
1)Activate meter on by pressing the ON/OFF/CAL button for 1 second.
2)Now press the ON/OFF/CAL button continuously for 3-4 seconds (you
will hear a beep) when “CAL” appears on the display.
3)The number 100 should appear on the display. If not; then press the
Range button to change the calibration value to 100.
4)Put the probe tip into the 100 ppm Ca++ Calibration Fluid. Wait until
the number 100 begins to flash on the display. This may take a minute or
so for a new probe. Let the flashing continue at least 3-5 minutes is
advised. Then press the Enter button to register the 100 ppm Ca++
calibration. The LCD should display the word “good”
5)Shake the probe dry. Press the Range button until 1000 is displayed.
6)Put the probe tip into the 1000 ppm Ca++ Calibration Fluid. Wait until
the number 1000 begins to flash on the display. This may take a minute
or two. Let the flashing continue for at least 3-5 minutes. Longer “flashing
time” will yield the most stable readings. Then press the Enter button to
register the 1000 ppm Ca++ calibration. The LCD should display the
word “good”.
7)Now press the ON/OFF/CAL button to read Calcium ppm.
8)Test your sample. Take a sample of water away from your system in a
clean cup and insert the probe to take a precision measurement. Allow
enough time for the reading to settle down.
9)Rinse the probe in RO or DI water, shake the probe dry and store it in
the protective bottle.
10)The meter will store the calibration even when the power is off.
•Calcium Monitoring
The accuracy of this and other electronic instruments is the greatest
immediately following a calibration process. Measure the calcium
frequently, if the value drifts, calibration should be performed to verify the
reading. The probe should not be totally submerged. Only the bottom
1 –2 inches of the probe tip should be in the water.

Important Points to Remember
• There are several possibilities for the meter to show “err” during the calibration process:
1-the probe tip is very dry (common with a new probe) and it should be hydrated by placing the tip into 1,000 ppm fluid
calibration fluid for and hour or so and then the 100 ppm calibration fluid for an hour. Then recalibrate.
2-The probe has reached the end of its useful life
3-The calibration fluids have become contaminated.
• At the end of the calibration process if the meter shows a ppm reading of zero; one or both of the calibration fluids may
be out of specification and are no longer accurate. Obtain new calibration fluids and recalibrate. Do not mix old
calibration fluids with new calibration fluids; discard the old set.
• Calcium Probe stability will be greatly improved when the probe tip is allowed to properly hydrate for 5-10 minutes in
any calibration fluid prior to calibration.
•PINPOINT Calcium Monitor is NOT waterproofand must be operated on a dry surface. Liquid contact with any of the
printed circuit boards will cause corrosion and void the warranty.
• Measurements above the instrument range will be indicated on the LCD as “HI”.
• The Calcium Probe tip should never be placed in RO or DI water for an extended period of time.
• If you observe an unusually high or low calcium ppm value, it is advisable to re-check the calibration.
• The Calcium Probe tip should be stored dry. The storage bottle can be used to prevent physical damage to the tip and
should not be filled with any fluid.
• The Calcium Meter will always store the last calibration even when the power is off.
• Replace batteries in the PINPOINT Calcium Monitor when the appropriate LCD battery icon appears.
•Display Range: 000.0 – 9,772 ppm Ca+
Resolution: 000.2 ppm
Accuracy: +/- 2 % of the reading after calibration
