4-20 mA Calibration
CAUTION The HDLT comes from factory calibrated and should normally not
require signal calibration. This should be done only if absolutely
necessary.
1. Click 4mA or 20mA to set the current output from the HDLT to 4 or 20 mA.
2. Measure the actual value of the current in the loop, enter it in the appropriate box, and
click Set. This recalibrates the signal to the entered value.
Entering a value in the lower box and clicking Set Current causes the HDLT to output the
entered current for testing purposes.
