Front Panel Keys (cont.)
L
Calls up a menu that allows you to specify limits
beyond which the Calibrator will not operate. This
can be used to set limits that protect both
operators and equipment.
Z
Changes the output to one tenth the reference
value (which is not necessarily the same as the
present output value). The value only changes if
the new value is within performance limits.
Y
Changes the output to ten times the reference
value (which is not necessarily the same as the
present output value). The value only changes if
the new value is within performance limits. This
key sets the Calibrator to standby if this change is
made from a value less than 22V to one that is
greater than or equal to 22V.
s
Causes the Calibrator to compute and display its
uncertainty for the present output setting for the
calibration interval and specification confidence
level selected in the setup menus.
o
Identifies a UUT zero-scale endpoint and does not
change the output. Subsequent keyed-in output
values have the offset value (the Calibrator output
value when o was pressed) added to them.
Offset mode is deactivated by pressing o again,
or by selecting another function. Offsets are
available for dc outputs only.
