Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
When the lower door is opened, the current measurement or calibration is stopped. When the lower
door is closed, the previous measurement or calibration starts again.
Set up the reagents and standards
Make sure to set the sample flow rate and install the reagent bottles before this task is started.
1. Push menu and then go to REAGENTS/STANDARDS.
2. Select one of the options. Use the SET options when the volume of existing reagents/standards
needs to be adjusted. Use the RESET options when reagents/standards are replaced or renewed
(bottles are replaced).

Grab sample options
The grab sample menu allows the user to analyze a specific sample or standard. Two options are
available:
• GRAB SAMPLE IN: This option is used to analyze an external sample or standard.
• GRAB SAMPLE OUT: This option is used to extract a sample directly from a sample line for
external analysis.

Description
Sets the volume of a specific reagent in the reagent bottle to an estimated value.
Range: 1–100%.
Sets the volume of a specific standard solution in the standard bottle to a calculated
approximate value. Range: 1–100%.
Sets the volume of the cleaning solution in the cleaning solution bottle to an estimated
value. Range: 1–100%.
Sets the volume of reagent in the reagent bottles to 100% full. IMPORTANT: make
sure to push enter, then select USER PREPARED REAGENTS if the reagents
were prepared in-house. Select HACH PREPARED REAGENTS if the reagents
were prepared by the manufacturer. This selection is important for accurate
measurements! Enter the reagent blank value for Hach reagents. Refer to
on page 20.
Sets the volume of standard solution in the standard bottle to 100% full.
IMPORTANT: make sure to push enter, then select USER PREPARED
STANDARDS if the standards were prepared in-house. Select HACH PREPARED
STANDARDS if the standards were prepared by the manufacturer. This selection
is important for accurate measurements!
Sets the volume of the cleaning solution in the cleaning solution bottle to 100% full.
Starts the flow of all reagents through the tube and valve system. IMPORTANT:
prime the reagents each time the reagents are changed to remove bubbles and
push the new reagents through the system.
