Charging the Lithium Battery
1. Before using the unit the first time:
Fully charge the battery. The unit was packaged and shipped from the
factory with the battery only partially charged.
2. When the battery is low:
The LOW-BATT LED will illuminate in red.
3. To recharge TIF IR-1A:
Plug one end of the charger into the top of the unit, and the other end
of the charger into the power source. The LOW-BATT LED will blink
while charging until the battery is fully charged.
NOTE: Charge within the charging environment specifications of
0 °C (32 °F) to 50 °C (122 °F) at <75 % RH.
4. Avoid discharging the battery completely.
Recharging a partially discharged battery more frequently is better for
the life of a lithium-ion battery.
Functions and Settings
ON/OFF Protection
Press and hold the ON/OFF button for one second to turn the TIF IR-1A
ON or OFF. This one-second delay protects against accidental ON or OFF.
LED Bar Graph Display
The eight-segment LED display indicates the degree of change in refriger-
ant concentration. As the concentration of refrigerant in the air increases,
the number of illuminated bars on the display increases also.
L/M/H Button (Sensitivity Levels)
Set the unit's sensitivity level by pressing the L/M/H button.
Low (L), medium (M), or high (H) sensitivity level is indicated by its
respective LED. The higher the background concentration of refrigerant in
the air, the lower the sensitivity level should be set. To detect a very small
leak in a high refrigerant background, use the Contaminate Mode.
Mute Button
Press the MUTE button to toggle the audio portion of the TIF IR-1A ON or
OFF.
Peak Button
The PEAK function stores the highest change in refrigerant concentration
achieved while continuing to detect leaks. Press the PEAK button to toggle
this function ON and OFF. The PEAK LED illuminates when this function is
turned on. Turning the PEAK function off clears the peak information.
