Calibration for Conductivity, TDS, or Salinity
1. P
ress MENU/v to enter setup window. Scroll down by pressing MENU/v to
select Settings.
For best results, periodic calibration with an accurate standard is recommended prior
to measurement. Use the calibration standard value that is close to your intended
sample value.The tester will retain one calibration value in each mode (conductivity,
TDS, salinity) when the instrument is powered off. The conductivity value can be
calibrated automatically or manually, while the TDS & salinity values require manual
calibration. The tester will begin in the measurement mode that was used when it was
powered off. See “Measurement Parameter Setting” to change the desired parameter.
2. Press HOLD/ to select Settings. The display shows TDS Factor and Backlight.

Manual Calibration
When the conductivity reading is outside calibration range of the automatic conductivity
standards or when TDS or salinity is used, the tester will require manual adjustment.
Getting Started
Temperature Calibration
The CTSTestr 50 Pocket Tester has been factory calibrated and usually works well
out of the box. However, after extended periods of non-use, it is best to remove the
sensor cap and soak the sensor in warm tap water for 10 minutes or so. Prior to
taking the measurements, periodic callibaration with certified standards is
recommended for best accuracy.
1. P

select Temp Set.
2. Press HOLD/ to select Temp Set. The display shows Set °C/°F, Temp Cal and
Temp Coeff.
Note: The adjustment will decrease only, however the adjustment will eventually cycle
to the highest available value after decreasing by 40% of the initial value.

Sensor Maintenance
1. Always keep the sensors electrodes clean. Rinse the electrodes with
deionized water and wipe them dry with clean cloth before storing with its
protective cap. For cup type electrodes, remove the white plastic cup and
insert to thoroughly clean viscous solutions. Never scratch electrodes with
a hard substance.
2. For better performance, soak the electrode in alcohol for 10 to 15 minutes and
rinse with de-ionized water before starting any measurement process. This is
to remove dirt and oil stains on the electrode which may affect the accuracy
of the measurements.
The CTSTestr 50 Pocket Tester uses four
AAA 1.5 V batteries.
1. To remove the battery cover, see Figure 1.
Clear the front catch and then the back
catch, before sliding the cover off.

Fig. 2: Push to unlock
2. T
o remove the battery plate, push the
center tab towards the front of the tester
as shown in Figure 2. Once unlocked,
remove the plate to access the batteries.
3. Invert the tester upside down to remove
the batteries. Each side uses two
AAA batteries. Orient each battery with
positive terminal facing downward.
