6.4.2-2 Automatic emissivity calculation (External: IR-FA
5
only)
: Selection of external programming
In the measurement mode, the emissivity is automatically calculated by entering the reference
temperature value by the analog input (option).
1) To select the external programming, press
SEL
key in the
measurement mode screen until “
Auto
” appears in the sub
display as shown in the right figure.
2) By pressing
key, “
ok
” will blink in the main display.
3) Confirm that the analog input is connected to the input/output
terminals (9 and 10).
(Ref. [5.1 Connections/Wirings])
4) To activate this selection, press
ENT
key.
6.4.3 Signal modulation mode selection
Two kinds of the signal modulation mode are available, one is “dELy” (displays the measured value
smoothly for fluctuating original signal) or the other is “PEAk” (displays the measured value by
modulating the original signal after the tracing of peak value).
To display the measured value based on the original signal, select “dELy” and program the modulation
degree to “0.0”. (Ref. [6.4.4-1 Modulation time constant programming])
1) To select the signal modulation mode, press
SEL
key in the
measurement mode screen until “
Modu
” appears in the sub
display as shown in the right figure.
2) By pressing
key, “
dELy
” or “
PEAk
” will blink in the main
display.
3) Use
△
or
▽
key to select the desired mode.
4) To activate this selection, press
ENT
key.
dELy
The measured value is displayed by the first-order
lag signal based on the modulation time constant
programmed in [6.4.4-1 Modulation time constant
programming].
PEAk
When the measured temperature is rising up, the
measured value is displayed by the original signal.
When the measured value is falling down, the
measured value is displayed by the damping
degree programmed in [6.4.4-2 Damping degree
selection].
Necessary to program the scaling of the analog input in [6.5.9 Analog input
programming]).
