Restek 22839 Instruction Manual

Only use the universal charger provided. The Leak Detector should be fully charged prior to use. When the unit’s charge is low, the green battery indicator LED light will begin to blink when the unit is powered up (Figure 1). The Leak Detector cannot be used during the charging cycle. 3.0 Powering Up Depress and hold the power button (Figure 1) until the unit responds with the wake-up mode. The leak detector will run through a self-calibration sequence for approximately 15 seconds. During this time DO NOT attempt to zero the unit. 4.0 Zeroing the Unit A ...

device employs a dual thermistor technology which measures the ratio of [probe]:[reference] heat exchange values and dis- plays the results on an LED scale (Figure 4). Under ideal operating conditions, a ratio of 1:1 indicates identical air samples for both [probe] and [reference], and therefore no leak is present. Because of slight differences in air temperature and/or humidity between the reference inlet (Figure 1) and the probe tip, a sm ...

Verify the operation of the Leak Detector before each use by sampling gas from a GC split vent, or other source of hydrogen or helium. Also, visually inspect the probe tip, reference gas inlet, and exhaust port for obstructions (Figure 1). IMPORTANT: Fittings being checked must be clean and dry; liquid leak detecting agents, dust, and other debris may damage the Leak Detector if drawn into the probe. The Leak Detector responds to almost any gas you can smell, and many gases that you can’t smell. Solvent vapors, split vent exhaust, or even strong air cu ...
