CALIBRATION:
• Immerse the meter in the proper
calibration solution: 1382 ppm
(M10032) for T75 and 6.44 ppt
(M10038) for T76.
• Unscrew the battery compartment
cap on the top of the meter.
• Allow the reading to stabilize and
with a small screwdriver turn the
calibration trimmer inside the bat-
tery compartment until the dis-
play shows "1382" for T75 or
“6440” for T76.
• Replace the battery compartment cap.
The calibration is now complete.
OPERATION:
• Remove the protective cap.
• Turn the meter on by pressing
the ON key.
• Immerse the probe in the solu-
tion to be tested.
• Stir gently and wait for the read-
ing to stabilize.
• After use, rinse the electrode
with water to minimize contami-
nation.
• Always replace the protective
cap after use.
Note: if the reading is over-
range, T75 will display “1”
while T76 shows “. . .”.
PROBE REPLACEMENT:
The probe can be easily replaced in the
following way:
• Remove the protective cap.
• Unscrew the plastic ring on
the top of the probe.
• Pull out the MA73075 (or
MA73076) probe and replace
it with a new one (aligning the
colored pin towards the LCD
side).
• Make sure the gaskets are in
place before screwing back
the plastic ring.
BATTERY REPLACEMENT:
The meter is supplied with BEPS (Battery
Error Preventing System) which avoids any
erroneous reading due to low battery level,
by switching the meter off. To replace the
batteries unscrew the battery compartment
cap and replace all three 1.5V batteries
while paying attention to their polarity. Make
sure the gasket is in place before screwing
back the cap.
Batteries should only be replaced in a non-
hazardous area using the battery type speci-
fied in this instruction manual.
