Low Battery Indication
A low-battery condition is indicated when the green power on LED begins
toash.Approximately20minutesofoperationtimeremainsfromthe

will gradually become erratic.
When a low-battery indication occurs, replace the batteries as described
under the previous Section Battery Installation.
Selecting High / Low Sensitivity Mode
WhentheTruPointeisrstturnedONitdefaultstoitslow-sensitivity
mode.
Place the instrument into its high-sensitivity mode by pressing the high/
low sensitivity button until the high sensitivity LED turns ON (high
sensitivity amber LED glows).
Tip: Use the low-sensitivity mode to extend battery and sensor
life. Use the high-sensitivity mode, if necessary, to pinpoint leaks.
Return the instrument to its low-sensitivity mode by pressing the high/
low sensitivity button until the high sensitivity LED turns OFF.
Procedure for Locating a Refrigerant Leak
Important: The instrument’s function is to detect a change
in refrigerant level, and not to make a quantitative measure-
ments. The technique of locating a leak by detecting a change
in level allows an operator to quickly locate the source of a
leak without making manual sensitivity adjustments, or be-
ing concerned about the background refrigerant level in the
surrounding area.
Begin by slowly moving the probe tip toward the area of the suspected leak
source. If surfaces are dirty or wet, wipe them off with a shop towel. Avoid
allowing dirt to clog the probe tip, or allowing water to enter the instrument.
