OPERATIONAL GUIDE

• Remove the protective cap
and turn the tester on by
sliding the top switch.

• Immerse the tester into the
solution up to the maxi­mum immersion level,
without touching the bot­tom of the beaker.

• Stir gently and wait for the reading to
stabilize. TDS1 automatically compensates
for temperature variations.

BATTERY REPLACEMENT

When the TDS1 can not be switched on or
the display fades, batteries have to be re­placed.

Pull out the batteries com­partment as shown in the
drawing, and replace all four

1.5V batteries, while pay­ing attention to the correct
polarity.

Batteries should only be replaced in a non
hazardous area and using the battery type
specified in this instruction manual.

CALIBRATION

• Immerse the tester into the
HI 70080 (800 ppm) cali­bration solution, without ex­ceeding the maximum im­mersion level.

• Allow the reading to stabi­lize and using the supplied
screwdriver adjust the cali­bration trimmer until the
nominal value of the solu­tion is displayed.

• Calibration is now complete.
