AUTOCAL to: 20°C
(0...50°C)
Start with Enter
Note: The AUTOCAL function plays a critical role in the
temperature accuracy of the controller. AUTOCAL should
only be executed when the machine has been idle long
enough for the heat seal band to be resting at ambient
temperature. If upon machine start-up the “Act” temper-
ature found on the Home Screen does not reflect the am-
bient temperature (+/- 1º) executing an AUTOCAL is re-
quired.
Pressing the Enter button

with or without changing the reference
temperature will started the AUTOCAL process.

AUTOCOMP is part of the calibration process that allows the con-
troller to compensate the phase angles between the Voltage (Ur)
and Current (Ir) measuring signals. AUTOCOMP will always running
after AUTOCAL.
Upon completion of AUTOCOMP the display will automatically ad-
vance to the following menus dependant on programming in Adv.
Configuration 301.
- Temperature coefficient (Tc) correction set to OFF in Adv. Con-
fig. 301 advances to Home Screen
- Temperature coefficient (Tc) correction set to “Single Pt.” along
with reset command in Adv. Config. 301 & 302a advances to
Settings menu 109.
- Temperature coefficient (Tc) correction set to “8 Point.” Along
with reset command in Adv. Config 301 & 302b advances to
Settings menu 110.
Settings Menu 109 - Single

SETTINGS 109
Sing. pt calibration
Set=888°C Act=888°C
Start with Enter
Settings menu 109 will only appear at the conclusion of Autocomp
when Single Point Temperature Coefficient (Tc) Correction has been
programmed in Advance Configuration menu 301 and a Single Point
Tc Correction reset has been requested in Advance Configuration
menu 302a.
Setting menu 109 is for Single Point Temperature Calibration. This
calibration feature enables the operator to calibrate the PIREG
®
-545
controller to a single temperature point with the aid of an independ-
ent NIST calibrated measuring device.
Note:
If no reset has been requested in Advance Config 302a
then the previous temperature coefficient correction will re-
main stored at the end of any subsequent Autocal process.
To start the single point temperature coefficient correction, using the
button, select the desired calibration temperature (“Set”), dis-
played on the left side of the screen and press the Enter
≡
button to
accept.
Press the Enter
≡
button again to start single point calibration.
On the right side of the display screen the actual value (Act) of the
PIREG
®
-545 is displayed (uncorrected). While the process is run-
ning, use the
button to set on the right side the actual measured
temperature of the heat seal band. The text “Act” will be change to
“Corr”. Press the Enter
≡
button to save.
Press the Enter
≡
button again to end the Single point calibration.
