LO % "LO" Battery Condition Caution: Power off the meter when changing battery. 3.4 Conductivity Electrode Information The Salt 6 salinity hand-held meter is supplied with a electrode with a BNC connector.
Instruction Manual Salt 6 Proper use of probe is essential to ensure that the optimum measurement is taken in a short time. The removable protective plastic probe guard is meant for simple periodic maintenance and it must be kept in tact during measurement and calibration. Always immerse the probe beyond upper steel band. NOTE: 1) DO NOT remove the protective probe guard during measurement and calibration as it may affect your readings.
Instruction Manual 3.5 Salt 6 Connecting the Probe to Meter 1) To connect electrode into meter, align the connector slots with the posts of meter’s socket and rotate connector clockwise until it locks. 2) To remove, simply rotate the connector in anti-clockwise direction until it unlocks, and slide the connector off the socket. 3) Insert the mini phono jack of temperature sensor into the socket on the meter as shown in Figure below.

Cell constant value is fixed, k=1.0.
Instruction Manual 3.7 Salt 6 Change Salinity ÙTemperature Measurement Mode To switch between Salinity measurement mode and Temperature measurement mode, simply press the MODE key. The customized annunciator helps indicate the measurement parameter you are in.
Instruction Manual 4 4.1 Salt 6 CALIBRATION Important Information on Meter Calibration The Salt 6 meter has a special built-in algorithm to linearize for the measurement of Sodium Chloride concentration. Therefore the specified accuracies from a One-point calibration anywhere in the measurement range, specified accuracies can be applied for the entire measurement range. When you recalibrate your meter, the old calibration will be replaced by the new calibration point.
Instruction Manual 4.2 Salt 6 Preparing the Meter for Calibration Before starting calibration, make sure you are in the correct measurement mode. Ensure that you use new Sodium Chloride standard solutions during calibration. Do not reuse standard solutions as it may be contaminated and affect the calibration and accuracy of measurements. Use fresh calibration solution each time you calibrate your meter. Store solutions in a dry and cool environment if possible.
Instruction Manual 4.3 Salt 6 Calibration for Salinity (% or ppt) The following example shows calibration sequence to 2.5% calibration standard. Procedure is similar for both % and ppt measurement mode. 1) If necessary, press MODE key to select measurement mode. 2) Rinse the probe thoroughly with de-ionized water or a rinse solution, then rinse with a small amount of calibration standard. 3) Dip the probe into the calibration standard.
Instruction Manual 4.4 Salt 6 Temperature Calibration The Conductivity electrode (EC-CONSEN91B/ 3560655) has a built-in temperature sensor for ATC. The temperature sensor is factory calibrated to the meter. Calibrate your sensor only if you suspect temperature errors that may have occurred over a long period of time or if you have a replacement probe. 1) Make sure that the phono jack (for temperature measurement) is properly connected to the meter. See Section 3.5.
Instruction Manual 5 Salt 6 MEASUREMENT The Salt 6 meter is capable of taking measurements with automatic or manual temperature compensation. 5.1 With Automatic Temperature Compensation (ATC) For ATC, make sure the phono jack of the probe (see Section 3.5) is securely inserted. The % or ppt reading displayed will be compensated for according to the normalization temperature (20 °C or 25 °C) selected. See Section 6.3 – Normalization Temperature.
Instruction Manual 5.2 Salt 6 Without ATC (Manual Temperature Compensation) For manual temperature compensation, simply unplug the probe’s phono jack (not BNC) from the meter. To use manual temperature compensation, you need to enter the temperature value of your process into the meter. This is the value at which the reading will manually temperature compensates. You can select any temperature between 0 and 50 °C. Default value is 25 °C.
Instruction Manual 5.3 Salt 6 Taking Measurements To take readings: 1) Rinse the probe with de-ionized or distilled water before use to remove any impurities adhering to the probe body. Shake or air dry. To avoid contamination or dilution of your sample, rinse probe with a small volume of your sample liquid. 2) Press ON to switch on meter. 3) Dip the probe into the sample. 4) Allow time for the reading to stabilize. Note the reading on the display.
Instruction Manual 5.4 Salt 6 HOLD Function This feature lets you freeze the display for a delayed observation. HOLD can be used any time in measurement mode. 1) 2) To hold a measurement, press the HOLD key while in measurement mode. [HO] will appear on the display. % HOLD ENTER HO To release the held value, press the HOLD again. Continue to take measurements. NOTE: This meter shuts off automatically after 20 minutes of non usage.
