The MTC tag and up & down arrow symbols light up on
the LCD to indicate that the meter is in MTC mode. The
arrow keys can be used to enter the desired tempera-
ture value.
Note: In MTC mode, the user can press and hold the
arrow keys to incrementing or decrementing
quickly the temperature value. The meter will
keep measuring and the display is updated ev-
ery second.
ORP MEASUREMENTS
To perform ORP measurements, connect the ORP elec-
trode (AD2015B/1, optional) to the meter and turn it on
by pressing the ON/OFF button.
If necessary, enter the ORP mode by pressing RANGE
until the display changes to mV.
Submerge the ORP electrode tip (4 cm) into the sample
to be tested and wait a few minutes for the reading to
stabilize.
Measurements within the ±699.9 mV range are displayed
with 0.1 mV resolution, while outside this range the reso-
lution automatically switches to 1 mV.

SETUP MENU
The instrument allows the user to configure the param-
eters through a setup menu.
To enter the setup mode, from normal measurement mode
press and hold the SETUP key for about 5 seconds.
The value of each parameter can be changed by using
the arrow keys and then confirmed with the CFM key.
After setting and confirming a parameter, the meter will
automatically show the next one.
ONE-POINT CALIBRATION
For optimum accuracy it is always recommended to per-
form a two-point calibration, but for a faster operation it
is also possible to carry out a single-point procedure.
The meter can be calibrated using any of the memorized
buffers, but the pH 7.01 or pH 6.86 value is normally the
most appropriate for a single-point procedure.
After calibrating the first point, press the CAL key to
exit the calibration mode.
