Manual Test Mode
The Hand-held’s manual test mode provides direct, real time control over the load bank’s
operation.
The following assumes that:
•
The Supply-on-Test and load bank settings have been made as described earlier in
this chapter.
•
You have pressed F4 (TEST) from either of the Settings screens on the Hand-held to
get to the test 1 page.
Using load correction
By default, the Hand-held provides closed loop load correction whenever you press the
I
key. This operates as follows:
•
The first time that a load is applied the Hand-held will look up in its internal load table
to see if it has a stored correction for that load value. If so, it will apply the stored
correction.
•
If no correction is found then it will calculate the load correction based on the actual
power measured with a compensation for the actual voltage and frequency
•
If the same load is applied a second time the Hand-held will always calculate a new
load correction. This load correction will be stored, replacing the previous correction.
•
You can force a new load correction at any time by pressing
I when the a load is applied.
•
The last sixteen load corrections are stored in the Hand-held’s memory. Restarting the
Hand-held, or pressing either NEW or CHECK, will clear the stored corrections from
memory.
