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 maxi-
mum immersion level,
without touching the bot-
tom of the beaker.
• Stir gently and wait for the reading to
stabilize. TDS1 automatically compensates
for temperature variations.
CALIBRATION
• Immerse the tester into the
HI 70080 (800 ppm) cali-
bration solution, without ex-
ceeding the maximum im-
mersion level.
• Allow the reading to stabi-
lize and using the supplied
screwdriver adjust the cali-
bration trimmer until the
nominal value of the solu-
tion is displayed.
• Calibration is now complete.
BATTERY REPLACEMENT
When the TDS1 can not be switched on or
the display fades, batteries have to be re-
placed.
Pull out the batteries com-
partment as shown in the
drawing, and replace all four
1.5V batteries, while pay-
ing 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.
