4.
The next screen requests you to enter the output current Measured value= measured
with your shunt. Enter it using the keypad and assure yourself the value is correct and
submit with ENTER.
5.
Repeat point 4. for the next three steps (total of four steps).
9.3.2
Calibrating Remote Sense
In the remote sensing feature is used, it is recommended to also calibrate this feature for best
results. The procedure is identical to the calibration of voltage, except it requires the sensing
connector (Sense) on the rear to be plugged in and connected with correct polarity to the DC
Input of the 6RL.
How to calibrate the output voltage for remote sensing
1.
Adjust the connected voltage source to approx. 102% of the maximum voltage specified
for the DC load. For example with an 80 V 6RL, this would be 81.6 V for the source. Set
the current limitation of the voltage source to 5% of the nominal current specified for the
6RL load – in this example it is 8.5 A. Check again, that for sense voltage calibration, the
sensing connector on the rear of the device is connected.
2.
In the display of the unit, tap MENU, then “General Settings“, then go to Page 7 and then
tap START.
3.
In the next screen select: Sense volt. calibration., then Calibrate input val. and NEXT.
4.
The next screen requests you to enter the measured sensing voltage Measured value= from
your multi-meter. Enter it using the key pad, that appears when tapping the value. Assure
yourself the value is correct and submit with ENTER.
5.
Repeat point 4. for the next three steps (total of four steps).
9.3.3
Calibrating Measurement Values
The actual value display of output voltage (with and without remote sensing) and output current
are calibrated the same way as the set values, but you do not need to enter anything, just
confirm the displayed values. Please proceed the above steps and instead of “Calibrate input
value” select “Calibrate actual val.” in the submenus. After the unit shows measured values on
display, wait at least 2 seconds for the measured value to settle and then tap NEXT until you
complete all steps.
9.3.4
Save Cal Coefficients and Exit
After calibration, you may furthermore enter the current date as “calibration date” by
tapping
in the selection screen and enter the date in format YYYY / MM / DD.
Last but not least save the calibration data permanently by tapping
.
Note: Leaving the calibration selection menu without tapping “Save and exit” will discard new
calibration data and the procedure will have to be repeated!
