Eagle Premier Series - CALIBRATION OF pH, ORP or FLUORIDE; PO1;PO2 (OUTPUT) CALIBRATION

7
• Set the mA generator to 4.00mA and press the pushbutton under the ZERO label to set the zero
ppm point. The display should read 0ppm.
• Set the mA generator to 20.00mA and press the pushbutton under the SPAN label to set the span
maximum point. The display should read the same as the PV1 FS parameter.
• If desired, repeat the above to verify calibration. However, the zero and span points are not
interactive so one can skip this step.
• Press the ESC pushbutton to exit to the calibration menu.
CALIBRATION OF pH, ORP or FLUORIDE
Selecting PV3 in the calibration menu will display the screen to the right.
Pushbuttons P1 and P2 set calibration points 1 and 2, respectively.
Pressing RST restores the default calibration values to (P1) 0.2ppm @
140mV & (P2) 2.0ppm @ 84mV. Pressing ESC backs to the calibration
menu.
Calibrate two points following a procedure documented in the probe manufacturer’s manual. P1 (point 1)
should be lower then P2 (point 2).
Fluoride: Do not calibrate from 0.0ppm to 0.1ppm of fluoride, as the probe is quite non-linear below 0.2.
Ammonia: Do not calibrate a zero ammonia value, select 0.01 instead. Calibrate the lower point using P1
and the higher point using P2.
PO1/PO2 (OUTPUT) CALIBRATION
To calibrate the analog output for channel one or two (PO1 or PO2), one must connect either a DMM (mA
input) or other device that can read the PO1/PO2 current output. The device should have, at least,
0.01mA precision. NOTE: PO2 is an optional board installed inside the PS-1000 enclosure.
1. From the calibration menu, press the POx pushbutton to enter the CAL ANALOG OUTPT (output)
screen.
2. Connect the DMM to the analog output that is being calibrated (PO1 or PO2) and press the PO1
or PO2 pushbutton to enter that calibration screen (SET ANALOG OUT).
3. Press the 4mA pushbutton and the mA meter should read around 4.00mA.
4. Use the UP & DOWN pushbuttons to set the output to exactly 4.00mA and press set when done.
This is the zero point.
5. Press the 20mA pushbutton; the mA meter should read around 20.00mA.
6. Use the UP & DOWN pushbuttons to set the output to exactly 20.00mA and press set when done.
This is the span point.
7. The two points are not interactive so one should not need to readjust each point again.
8. Press the EXIT pushbutton to go back to the CAL ANALOG OUTPT menu. One can calibrate the
other channel if desired.
