EC/TDS OPERATIONS
• The user can select the EC/TDS
conversion factor (CONV), as well as
the ß coefficient (BETA) for automatic
temperature compensation.
• Enter the EC or TDS mode with the
“RANGE” key, then press and hold the
“ON/OFF” key until “TEMP” is displayed
on the secondary
LCD. Press this key
again to show the
current conversion
factor (CONV).
• Press the “SET”
button to change the
value, then press
again this key to show
the current
temperature coefficient (BETA).
• Press “SET” to change the value, then
press “ON/OFF” key to return to normal
operation.
• For taking EC or TDS measurements,
immerse the probe in the solution to be
tested.
• Select either EC or TDS mode with
“RANGE”.
• Stir gently and wait for the reading to
stabilize
(the clock symbol stops
blinking).
EC/TDS CALIBRATION PROCEDURE
• Clean the probe with
M10000
solution.
• Enter the EC mode with the “RANGE”
key.
• Immerse the probe in
MA9030
(12.88
mS/cm) calibration solution.
• Press and hold the
“ON/OFF” key until
“CAL” is displayed on
the LCD. Release the
button and the
message “12.88 mS USE” appears.
• The meter will perform automatic
calibration, and then display “OK” for 1
second before returning to normal
mode.
• The calibration is now complete and
the “CAL” tag is displayed on the LCD to
indicate that the meter is calibrated.
BATTERY REPLACEMENT
The meter shows the remaining battery
percentage every time it is switched on.
When the battery level is below 5%, the
battery symbol on the bottom left of the
LCD lights up to alert the user.
The meter is also provided with BEPS
(Battery Error Prevention System),
which automatically switches the meter
off if the battery level is so low to cause
erroneous readings. It is recommended
to replace immediately the battery.
Turn the meter off,
remove the battery
compartment cover
from the rear of the
meter and replace
the rundown 9V
battery with a new
one.
Install the battery
while paying
attention to its
polarity and reattach
the cover.
NOTES
• If reading is over-range, the display will
flash the closest full scale value.
• To clear a previous calibration, press
“ON/ OFF” after entering the calibration
mode. The lower LCD will display ESC
for 1 second and the meter will return to
normal measurement mode. The “CAL”
symbol on the LCD will disappear and
the meter is reset to the default
calibration.
