1. 

Press the MODE key

to select the meas-

urement mode in which you need to use
manual temperature compensation. 

2. 

If necessary, select ATC off.
pH:

see NOTE on page 17

Conductivity/TDS:

see page 21

When ATC is off, the ATC indicator 
disappears from the lower right corner
of the display.

3. 

Press the CAL/MEAS key

to enter 

calibration mode. The CAL indicator 
will appear above the primary display.

See figure 

4. 

While in calibration mode, press 
the MODE key

to enter temperature 

calibration mode. The primary display
shows the current temperature setting
and the secondary display shows the 
last set temperature value. 

See figure 

5. 

Check the temperature of your sample
using an accurate thermometer.

6. 

Press the

or

keys

to offset the 

temperature to the measured value 
from step 5.

See figure 

7. 

Press ENTER

to confirm the selected

temperature and to return to measure-
ment mode.

Selecting the manual temperature compensation value

To use manual temperature compensation, you need to enter the temperature 
value of your process into the meter. This is the value at which readings will 
manually temperature compensate. You can select any temperature between 
0 and 100°C (32 and 212°F). Default value is 25°C (77°F).

To select a manual temperature compensation value:

D

D

E

E

F

F

The meter will now compensate readings for the manually set temperature.

Notes

To exit this program without confirming the manual temperature compensation value, 
DO NOT press ENTER in step 7. Press CAL/MEAS instead.

Setting the manual temperature compensation value for conductivity or TDS will change
the manual temperature compensation value for pH to the same value, and vice versa.

6. Advanced set up functions

The advanced set up mode lets you customize your
meter’s preferences and defaults. Your waterproof
meter features different sub groups that organize all
set-up parameters. 

This meter blanks out sub groups that do not apply
to the measurement mode [conductivity/TDS or pH]
you are in when you enter Setup mode.

The full selection of available sub groups are: 

pH sub groups
1.

P1.0:

Viewing pH calibration data

2.

P2.0: 

Viewing pH probe data

3.

P3.0:

pH configuration

4.

P4.0:

Resetting meter to factory default 
( pH settings)

Conductivity/TDS sub groups
5.

P5.0:

Viewing conductivity (TDS) calibration data

6.

P6.0: 

Viewing conductivity (TDS) probe data

7.

P7.0:

Conductivity (TDS) configuration

8.

P8.0:

Conductivity (TDS) temperature parameters

9.

P9.0:

Resetting meter to factory default 
(conductivity/TDS settings)

See pages 24-25 for a more detailed overview 
on the different parameters available in the 
sub group modes.
