The specifications of the dosing accuracy is

0.1%
of full burette volume (

0.1% * 25 mL =

0.025
mL). For the accuracy of other burette volumes, see
the HI 901 / HI 902 Instruction Manual.
If the results are not correct, check all fittings for
leakage, and burette and tubing for air bubbles.
Repeat the measurements.
The table below contains the settings to be used for
other burette volumes:

Temperature Channel Fast Check Procedure:

Connect the shorting cap to the BNC socket on
Analog Board 1.

Connect the HI 762000C 0°C temperature key to
the RCA socket (temperature sensor input) on
Analog Board 1.

Once on the main screen select “
Mode
”, ensure
that Analog Board 1 is active then select “
mV 1
”.

Press “
General Options
”, use the arrow keys to
highlight ‟Temperature‟ and press “
Select
”.

Select „Temperature Source‟ and then „Automatic
Temperature‟.

Press “
Escape
” two times to return to the main
screen.

The titrator should display ATC 0.0

0.4°C with
no fluctuation or drift.

Connect the HI 762070C 70°C temperature key to
the RCA socket (temperature sensor input) on
Analog Board 1

The titrator should display ATC 70.0

0.4°C with
no fluctuation or drift.
Note: This procedure can be repeated on analog 2
Temperature & mV Channel Logging Procedure :

Connect the shorting cap to the BNC socket on
Analog Board 1.

Connect the HI 762000C 0°C temperature key to
the RCA socket (temperature sensor input) on
Analog Board 1.

Once on the main screen select “
Mode
”, ensure
that Analog Board 1 is active then select “
mV 1
”.

Pr
ess “
General Options
”, use the arrow keys to
highlight ‟Temperature‟ and press “
Select
”.

Select „Temperature Source‟ then „Automatic
Temperature‟.

Press “
Escape
” two times to return to the main
screen.

Press “
mV Setup
”, use the arrow keys to highlight
‟Logging Interval‟. Set the logging interval to 15
seconds and press “
Accept
”. Press “
Escape
” to
return to the main screen.

Press the “result” key and use the arrow keys to
highlight ‟Setup pH/mV/ISE Report‟. Press
“
Select
”.

Select „Potential‟ and 'Temperature and Units‟ (the
selected fields are marked with an “
*
”). All other
fields should be unselected.

Press “
Save Report
” to return to the Data
Parameters screen.

Press “
Escape
” to return to the main screen. Once
on the main screen, select “
Mode
” then “
mV 1
” to
enter mV mode on Analog Board 1.

Press “
Start Log
” to start the automatic log.

Let the log run for about 10 minutes. Press “
Stop
Log
” to stop the automatic log.

Press “
Result
”, highlight „Review Available
Reports‟, and press “ View Report”.

The mV column should display 0.0

0.1 mV, and
the temperature column should display 0.0°C

0.4°C.

This procedure can be repeated using the HI
762070C 70°C temperature key.
Note: This procedure can be repeated on analog 2
