Hanna Instruments DiST HI 98302 User manual

OPERATION:
• Remove the protective cap.
• Turn the DiSTDiST
DiSTDiST
DiST on.
• Immerse it in the solution to be tested without
exceeding the maximum immersion level.
• Stir gently and wait for the reading
to stabilize.

DiST automatically compensates for
temperature variations.
• The reading on display is directly expressed in:

CALIBRATION:
• Immerse the DiSTDiST
DiSTDiST
DiST in the indicated calibration
solution (see Specifications), without exceeding
the maximum immersion level.
• Allow the reading to stabilize and with a small
screwdriver turn the calibration trimmer until the
display shows the required solution value.
E.g. for calibrating HI98301HI98301
HI98301HI98301
HI98301 the correct calibra-
tion solution is HI70032HI70032
HI70032HI70032
HI70032, and the trimmer should
be turned until the display shows "1382".
BEPS AND BATTERY REPLACEMENT:
DiSTDiST
DiSTDiST
DiST is supplied with BEPS (Battery Error Preventing
System) which avoids any erroneous reading due to
low batteries level, by switching the meter off.
To replace the batteries, slide off the battery com-
partment cover and replace all four 1.5V batteries
while paying attention to their polarity.
Batteries should only be replaced in a nonhazardous
area using the battery type specified in this instruction
sheet.

• Before reinserting the internal circuit into the
new plastic casing, make sure the O-rings (2)
of the temperature sensor (3) are properly
seated (see drawing).
To avoid bending the connections to the con-
ductivity sensors (1), do not apply excessive
force while inserting the circuit. In case of any
problem, reslide and reinsert it.
Internal circuit:
• Fasten the screw on the back, below the
battery compartment.
• Reinsert the battery compartment cover.
• Recalibrate the DiSTDiST

DiST before performing new
measurements.
