MAX/MIN Function
1.
Press and hold the Max/Min button to access the Maximum/
Minimum modes.
2.
The MAX and MIN indicators will blink continuously. The Maximum
& Minimum values will automatically update in the Max/Min memory
while the current applicable measurements are displayed.
3.
To view the Max/Min measurements during this mode press the
Max/Min button at any time to toggle through stored
measurements.
4.
To exit Max/Min mode and resume normal operation, press and hold
the Max/Min button for approx. 3 seconds.
Auto Power Off
To preserve battery life, the meter is programmed to turn off after
approximately 10 minutes of inactivity.
Calibration
Meter accuracy should be performed on a periodic basis. If calibration
is required, a conductivity standard solution is required. The meter can
be calibrated in any of the three ranges. Standard solutions of 84µS/cm,
1413µS/cm (included) or 12.88mS/cm (12,880µS/cm) are used for the
automatic calibration recognition procedure.
Note:
Calibration is always done in conductivity mode. Since salinity and
TDS values are calculated from conductivity values, this procedure also
calibrates the salinity and TDS ranges.
1.
Fill a sample cup with the conductivity standard solution.
2.
Turn the meter ON and insert the electrode into the solution so that
the tip of the electrode is fully immersed and stir at a moderate,
uniform rate. Tap or move the electrode in the sample to dislodge
any air bubbles.
3.
Press and hold the
CAL
button (approximately 2 seconds) until
"CAL" appears in the lower display. The main display will
start flashing.
4.
The meter will automatically recognize and calibrate to the
conductivity standard solution.
