Hach H160G - Set the Conductivity Options; Set the TDS Options

Set the conductivity options
Set the calibration alarm, the conductivity temperature compensation, the 2, 3, 4 or 5-point
conductivity calibration, the conductivity temperature and the cell constant.
1. Set the power to on.
2. Push SETUP, then COND to put the meter in conductivity setup mode.
3. Use the arrow keys to select an option, then push ENTER:
Operation Function
ISE calibration alarm Sets the alarm from 1 to 999 hours. The recalibration alarm is set to "OFF" at
000 hours.
Conductivity temperature
compensation
• Use the arrow keys to set the compensation coefficient between 0 to 10 (the
default is set to 2% per ºC).
• Conductivity is automatically temperature compensated.
2, 3, 4 or 5-point
conductivity calibration
• Use the arrow keys to select each option, then push ENTER:
• Shows the first active calibration point. Use the arrow keys to see other in-use
values.
Note: "- - - -" shows on the display if there are no conductivity calibration points in storage.
Conductivity
temperature
1
• Shows the conductivity normalization value.
• Use the display settings between 20 to 25 °C (default = 25 °C).
Conductivity probe cell
constant
The cell constant is automatically found and shows on the display. Sets the cell
constants to:
• K = 0.5 for general procedures
• K = 1 for low conductivity procedures (e.g., drinking water)
• K = 10 for salinity or brackish water
• If no conductivity probe is attached, the display shows "000."

Conductivity varies a lot with temperature. The Automatic temperature compensation (ATC) adjusts
conductivity measurements to calculate the conductivity changes in the reading that are caused by
temperature. The readings are referenced to or "normalized" at a standard temperature. The ATC gives the
equivalent conductivity or TDS of a solution normalized at 20 or 25 °C.
4. Push ENTER to keep the changes and go back to setup mode.
Note: To exit and not keep the changes, push CANCEL.
Set the TDS options
Set the TDS conversion factor, the TDS units and the salinity units. Complete the operations in order.
1. Set the power to on.
2. Push SETUP, then ISE to put the meter in ISE setup mode.
3. Use the arrow keys to select an option, then push ENTER:
Operation Function
TDS conversion factor
• TDS values are related to conductivity. Calibrate with a TDS standard or with
conductivity standards, then program the meter with a conversion factor.
• Sets the conversion factor to 0.40 to 1.00 (default is set to 0.50).
TDS units Use the arrow keys to set the TDS units in mg/L (g/L) or ppm (ppt).
Salinity units in ppm (ppt)
or %
Use the arrow keys to set the salinity units in ppm (ppt) or as a percentage.
