Tension calibration
Weightless calibration
Use this method when applying a known weight is not
convenient or desired.
For Precision Calibration method, see page 4-5.
Enter the programming mode by pressing and holding [+] and
[-] for two seconds.
Use the [+] and/or [-] buttons to go to parameter P.01. Press
[
] to see the present load cell excitation voltage. Select either
5V or 7.5V. When using MAGPOWR load cells select 7.5V. Press
and hold [
] for two seconds (until the display starts flashing)
to store the changes.
Use the [+] and/or [-] buttons to go to CAL2. Press [
] to enter
the CAL2 sub-menu.
Display now shows C2.1. Unload the load cell roller and press
[
]. The DTR-65 will now zero out the idler roll weight and
show a wait display. After zeroing the DTR-65 will automatically
increment to the next parameter.
Display now shows C2.2. Press [
] and select the decimal point
position for tension. Press and hold [
] for two seconds (until
the display starts flashing) to store the decimal point position
chosen. Range {0000, 0000., 000.0, 00.00, 0.000}.
Display now shows C2.3. Press [
] and enter the load cell
sensitivity in mV/V units. MAGPOWR load cells have a sensitivity
of 2.1 mV/V. (Consult the manual of competitor's load cells if
using non-MAGPOWR load cells.) Press and hold [
] for two
seconds (until the display starts flashing) to store the
parameter. Range {000.1, 100.0}.
