4.5.3 CALIBRATION CONTROLS
NOTE : Before performing calibration, set BHK for local sensing (cS to + OUT
terminal and connect –S to –OUT terminal at the rear panel).
After turning the
unit on It is necessary to wait 15 minutes before calibrating the unit to allow
for thermal stabilization.
NOTE: The left and right single arrow buttons ( << and >> ) that appear on the calibration
screens are equivalent to the front panel left and right arrow keys. The left double
arrow button (
<< ) is equivalent to the 1 key on the front panel keypad; the right double
arrow button ( >> ) is equivalent to the 3 key.
All adjustments are done using the four arrow buttons that appear during Calibration (see Figure
4-3 and Table 4-2). The double arrow buttons
<< and >> either increase ( >> ) or decrease ( << )
the output by a maximum of 18 steps (each step is one LSB (Least Significant Bit), equivalent to
0.024% of nominal value) at a time; the
> and < buttons either increase ( > ) or decrease ( < ) the
output one step at a time.
