EPT
AUTO
function enabled. After setting the EPT = AUTO function using the F4 key, the elec-
trode is immersed into a liquid. To perform the measurement, press MEAS. the EPT symbol
blinks to indicate that the measurement is in the stabilization phase. In the stretch indicated by
1, the measurement remains within a stability range for 8 seconds: at the end of this interval
(point 2), the instrument freezes the measurement, presenting the final stable value. The EPT
AUTO symbol stops blinking.
For a new measurement, press MEAS.

ATC or MTC indicate the temperature compensation type being used.
ATC
means automatic compensation: If the temperature probe is present, compensation is car-
ried out according to this probe, or according to the temperature detected by a combined
probe, if present. In this case, you cannot modify the manually input temperature value.
MTC
means manual compensation: there are no temperature sensors; the temperature used for
compensation is typed using the keyboard. Press the “F5 - °C/°F” key once to modify its
value: the message
e
blinks. Use the
and
arrows to set the desired value and con-
firm with ENTER. The display stops blinking, and the temperature displayed is used for
compensation.
If the temperature probe is not present, in order to change the unit of measurement between °C
and °F, it is necessary to press the F5 = °C/°F key
twice
