SENSITIVITY Setting – press the SETUP push button to advance to the Sensitivity

function. This feature adjusts how the J Type reacts to input voltage waveform

distortion and momentary power ﬂuctuations. It allows you to adjust the sensitivity

of the J10 and J15 to LOW, MEDIUM, and HIGH (Figure 20) using the SETUP and

Up/Down Arrow push buttons. The Sensitivity adjustments have the following

value:

HIGH Sensitivity – should be used when the connected equipment is sensitive to

momentary low voltage or brief power ﬂuctuations. In HIGH Sensitivity the unit is

very sensitive to voltage distortion and is, therefore, more likely to switch back and

forth to battery power than it would under a MEDIUM or LOW sensitivity setting.

MEDIUM Sensitivity – is the default setting suitable for most situations.
