TIF ZX Heated Pentode Refrigerant Detector - Manual (Page 11)

9
When a refrigerant is detected, the visual indicator lights from left to right; first in
green, then sequentially in orange, and then sequentially in red . Often, on anything but
the smallest leak, the extreme sensitivity of the unit may cause the LEDs to all light in
orange or red . Since each LED can appear in one of three colors – green, orange or
red – this will result in 15 distinct alarm levels .
WaRninG: to prevent personal injury, do not use this leak Detector in
an explosive or combustible atmosphere. ambient atmosphere is drawn
through the probe and sensor, which operate at a very high temperature.
the resulting hot mixture of air and combustible gas could explode.
1 . Press and release the ON/OFF Key to switch the unit on .
2 . The LEDs begin cycling in orange, from left to right, to indicate warm-up . The warm-
up time is fixed at 20 seconds .
3 . After warm-up, all LEDs briefly flash orange, indicating the unit is ready for use . The
unit begins beeping at a steady rate (two quick beeps approximately once every two
seconds – indicating HIGH sensitivity) . The first LED displays the battery voltage
level as described in the Constant Power Indicator section .
4 . Set the sensitivity level you wish to use, as described in the Sensitivity Adjustment
section .
