6.2 Units
The units are shown after the measured value as two 16-segment characters.
Depending on the programming (see Manual, Section 6.3.5) units other than
the standard units can be stipulated per measuring range; (see Man. Sec. 6.1).
For degrees Fahrenheit
°F
the temperature value is converted from
degrees Celsius. With the character
C
or
F
, cold junction com-
pensation is disabled.
The units

7. MEASURING OPERATIONS
With measuring instrument ALMEMO
®
2390-3 all available measuring chan-
nels are scanned continuously; this permits continuous differential measure-
ments and ensures continuous temperature compensation for dynamic pressu-
re probes or chemical probes; (see Manual, Section 6.5.1.3).
Up to 12 measuring points can be displayed; (see Section 7.1).
A measured value can be sent to an analog output; (see Manual, Sec. 5.1.1)
7.1 Selecting the meas. value and the measuring point
After the device is switched on, the
MEASURE
function is set and measuring
point M0 for the first sensor is selected automatically; i.e. measured value M0
is shown in the display. After calling up other functions you can revert to the
MEASURE
function by means of key
M

In the
MEASURE
function it is also possible, by means of key
M
▲
, to successi-
vely select all other active measuring points and have the current measured
value of each one displayed. If keys
M

is pressed and held down (for approx.
1 second), the previous channel is displayed again.

If, when switching measuring channels, the measuring range changes, the ab-
breviation for the measuring range is displayed for a moment first; (see Section
6.1).This abbreviation also flashes in the event of sensor breakage - instead of
