Prepare The Sensors For Calibration; Deployment Guidelines - HYDROLAB HL Serie Manual De Usuario

• Set the calibration mode.
• Select the measurement units shown during calibration and calibration checks.
• Look at the calibration history.
To look at the Hydrolab Operating Software Manual, start the Hydrolab Operating Software, click
Help and select Hydrolab Operating Software Help.
When a calibration or a calibration check is started, the step-by-step instructions for the sensor show
on the display.

Prepare the sensors for calibration

Before calibration, always rinse the storage/calibration cup and clean the sensors to prevent
contamination of the calibration standards.
1. Rinse the storage/calibration cup with clean water.
2. Clean the sensors. Refer to the sensor documentation for instructions.
3. Rinse the sensors at least three times with deionized water. Refer to
Note: Figure 7 shows the HL4 sonde. The steps are the same for the HL7 sonde.
4. Rinse the sensors at least two times with a calibration standard. Refer to
For the best results, discard the deionized water and calibration standard after each rinse.
Figure 7 Rinse the sensors

Deployment guidelines

Always install the mooring cap or connect the deployment cable to the instrument before deployment to keep the
connector dry. Do not use the calibration cable for deployment because the connector will get wet.
Always install the sensor guard before deployment or sensor damage can occur.
• Do not apply more than 68 kg (150 lb) of additional weight to the instrument when the mooring cap
is used.
• Do not apply more than 113 kg (250 lb) of additional weight to the instrument when the
deployment cable is used.
• Do not hang weight from the sensor guard. Refer to
strength of the mooring cap and deployment cable.
