The screen
The TC-TM66XX range is fitted with a graphic LCD display with back-lighting. The display resolution is 160 x 160 pixels.
In normal operating conditions, the display is divided up into seven horizontal fields:
•
st
The 1
field indicates the operating mode (Measurement or emission).
•
nd
The 2
field indicates the date, time and battery charge.
•
rd
The 3
field is reserved for icons indicating the operating mode (related functions: Scaling, filtering...etc).
•
th
The 4
field indicates the operating mode, the gauge and certain related functions.
•
th
The 5
field indicates the value of the measurement or of the emission. These values are expressed in mV, Ohm, °C, °F or as a %...
•
th
The 6
field indicates (in measurement mode) the min., average and max. values of the measurement.
•
th
Lastly, the 7
field indicates the functionality of keys F1 and F2.
