OPERATION
Using the LDA1000H
Turning the instrument ON:
Press the red START button once to turn the unit ON. The instru-
ment initiates a sensor self-cleaning and conditioning cycle which
lasts for 35 seconds. During that time, the bar graph indicator
lights scan from left to right. When the audible alarm turns on
the instrument is ready to use.
Sensitivity settings:
The LDA1000H features 8 manually selectable settings, 4 for the
R-134a mode—L, M, S and SC—indicated by blue LED's, and 4
for the HFO-1234yf mode—L, M, S and SC—indicated by white
LED's. The instruments starts in the Large Leak (L) setting for
the R-134a mode and advances clockwise with every press of
the red START button.
The unit will always start in lowest sensitivity position in the R134a
mode. In this mode, the instrument responds to leak rates equal
to or greater than 14 g / yr (0.5 oz / yr.).
The bar graph indicator shows the user how much bigger than that
leak rate the detected leak is. If no indication is obtained in that
setting, then press the red START button to advance the sensitivity
to the 7 g / yr. (0.25 oz / yr). If no indication is obtained in this
range, then press START again and go the highest sensitivity
setting of 4 g / yr (0.15 oz / yr).
Pressing the START button once again puts the LDA1000H in
a unique setting especially designed to be used in heavily con-
taminated atmospheres. This setting is identified by a lower tone
alarm which increases in volume and frequency when the leak is
detected in the contaminated atmoshpere.
Pressing the START button once more puts the instrument in the
lowest sensitivity setting of the HFO-1234yf mode. Subsequent
activation of the START button repeats the above sequence for
the HFO-12134yf refrigerant.
Note: The LDA1000H is sensitive to all refrigerants currently
used in the automotive industry. If the vehicle being checked
for leaks uses a refrigerant other than R-134a or HFO-1234yf,
use the R-134a mode of the LDA1000H.
Turning the instrument OFF:
At any time during operation, press and hold down the red START
button until the LED display turns OFF. This indicates that the unit
has been shut down.
Low battery indicator

When the batteries reach approximately 10% of capacity, the green
LED next to the symbol (
