Select the first current calibration point for the +6V supply.
The display shows the first current calibration point for the +6V supply.
11
Read the DVM and change the first current value on the display to
match the computed current (DVM reading
¸ by shunt resistance).
For example, if the computed value is 0.099 A, adjust the current to 0.099 A
using the knob and arrow keys.
Notice that you should wait for the DVM reading to stabilize for accurate
calibration.
12
Pressing the "Calibrate" key saves the change and selects the second
current calibration point for the +6V supply.
If the entered number is within an acceptable range, an "ENTERED" message
appears for one second. The display now shows the second current calibration
point for the +6V supply. If the entered number is not correct, an "INVALID
DATA" message appears for one second and the display shows the first current
calibration point again.
Connect an appropriate shunt (see Table 3-1 on page 42) across the +6V
supply's output terminals, and connect a digital voltmeter across the
shunt resistor for the current calibration.
