OPERATION
• Remove the protective cap.
• Turn the meter ON sliding the
switch on the top.
• Immerse into solution up to
the max immersion level with-
out touching the bottom of the
beaker.
• Stir gently and wait until the
display stabilizes. Readings are
automatically compensated for
temperature variations.
• The value on the display has
to be multiplied by a factor of
10 for DiST1 & DiST3 and
by a factor of 100 for DiST2
& DiST4 (as shown on the
upper left corner of the LCD) to give
direct reading in ppm or µS/cm.
CALIBRATION
• Immerse the tester up to the maximum
immersion level in the appropriate cali-
bration solution (see Specifications).
• Allow the reading to stabilize and using
a small screwdriver adjust the calibra-
tion trimmer to match the solution value.
E.g. calibrating DiST1 with HI70032P
solution, turn the trimmer to read "138"
(x10 = 1380 ppm).
BATTERY REPLACEMENT
When the meter cannot be switched on or
the display fades, pull out
the battery compartment and
replace all four 1.5V batter-
ies, while paying attention
to their polarity.
Batteries should only be re-
placed in a safe area using
the battery type specified in
this instruction manual.

could cause interference to radio and TV equipment.
The pins at the end of the sensor are sensitive to
electrostatic discharges. Avoid touching this metal band
at all times. Any variation introduced by the user to the
supplied equipment may degrade the instrument's EMC
performance. To avoid electrical shock, do not use this
instrument when voltages at the measurement surface
exceed 24 Vac or 60 Vdc. To avoid damage or burns, do
not perform any measurement in microwave ovens.
