SALINITY CALIBRATION

Note:

Salinity calibration is made in conductivity mode when using Natural Sea Water or Practical Sea
Water measurement. Direct salinity calibration is only possible when using the older percent scale.

Salinity calibration is a single-point calibration procedure at 100.0%. Use the

HI 7037L

calibration

solution (salinity solution) as a 100% seawater solution.
To enter salinity calibration:
• Set the meter for salinity range.
• Select the

Percent Scale

(see

Salinity Setup

section).

• Rinse the probe with some of the calibration solution or deionized water.
• Immerse the probe in

HI 7037L

solution. The sleeve holes must be completely submerged. Tap the

probe repeatedly to remove any air bubbles that may be trapped inside the sleeve. Position probe away
from the wall or bottom of the container.

• Enter in calibration mode by pressing

.

• Wait for measurement to stabilize.
• Press

to finish salinity calibration or press

to cancel calibration.

CALIBRATION MESSAGES

•

Wrong standard solution. Check the standard solution.

This message appears when the difference

between the reading and the value of the selected standard is significant. If this message is displayed,
check if you have selected the appropriate calibration standard.

•

Wrong standard temperature.

This message appears if the standard temperature is out of the

allowable standard temperature range (0 - 60 °C)

.

•

Press <Clear Cal> to clear old calibration.

: Clear the old calibration.

Make sure the TDS factor has been set before taking TDS measurements (see

TDS Setup

section).

Also the TDS calibration is made in

Conductivity

mode.

DIRECT MEASUREMENT

To measure the TDS of a sample using the

Direct

reading mode:

• Press

and then

to select TDS measure

mode.

• Select the

Direct

reading mode (see

TDS

Setup

section).

• Proceed the same as for the conductivity measurement (see

Conductivity Measurement

section).

DIRECT/AUTOHOLD MEASUREMENT

To measure TDS of a sample using the

Direct/AutoHold

reading mode:

• Select the

Direct/AutoHold

reading mode (see

TDS Setup

section).

• Proceed the same as for the conductivity measurement. (see

Conductivity Measurement

section).
