3.3 Setting the Conductivity calibration standard
The factory default for this item is 2.76mS/cm. If this is satisfactory, go directly to section 3.4.
1. Select the Conductivity Standard entry
(
→
→
F4:Setup
→
→
F1:Standards
→
→
F1:Conductivity
).
The following screen is now displayed…
Conductivity
Standard:2760.uS/cm
Range
20uS/cm to 2000mS/cm
2. Type in the value of the Conductivity standard that is to be used for calibration, including the
decimal point. Use the
key to make any corrections.
3. Press
to save the value of the standard solution.
Alternatively, press
to quit without changing the current setting.
4. The
smart
CHEM
-C
will now ask you to enter the units for the Conductivity standard…
Conductivity
Standard:2760
Select Units
F1:uS/cm F2:mS/cm
(a) If the
smart
CHEM
-C
is set up for S/cm (section 3.2)…
Press
to set the Conductivity Standard as µS/cm.
Press
to set the Conductivity Standard as mS/cm.
or (b) If the
smart
CHEM
-C
is set up for S/m (section 3.2)…
Press
to set the Conductivity Standard as µS/m.
Press
to set the Conductivity Standard as mS/m.
Press
to set the Conductivity Standard as S/m.
or (c) If the
smart
CHEM
-C
is set up for dS/m (section 3.2), dS/m is set as the unit for the
standard.
5. The Conductivity standard is now programmed for use at calibration.
3.4 Setting the Reference Temperature
The factory default setting for this item is 25
O
C. If this is satisfactory, go directly to section 3.5.
1. Select the ATC configuration menu.
(

→
F4:Setup
→
→
F6:Next
→
→
F3:Reference Temp.
)
2. Press
to reference all readings to 25
O
C for Automatic Temperature Compensation.
Press
to reference all readings to 20
O
C for Automatic Temperature Compensation.
Press
to quit without changing the current setting.
