GENERAL INFORMATION
LDA1000H Overview
The LDA1000H is the first automotive electronic leak detector
utilizing E_MOS™ sensor technology. Following the guidelines
of the latest SAE standard specifications for leak detectors, the
LDA1000H offers the user two detection modes: one optimized
for R-134a and the other for HFO-1234yf. Each mode has three
sensitivity settings according to the requirements of the SAE
standards. Efficient control of the power to the sensor increases
the life of the batteries while ensuring that the sensor is operated
at its optimum condition in every mode. Although designed
with SAE standards in mind, the LDA1000H’s advanced sensor
technology is sensitive to all CFC, HCFC and HFC refrigerants
as well as approved blends. The LDA1000H is housed in an
ergonomically shaped high impact plastic chassis with a flexible
15" probe for rugged automotive use. The E_MOS™ sensor is
enclosed in a metal cage designed to protect the sensor from dirt
and water. The sensor housing incorporates an easily removable
threaded cap with a filter, allowing the user to conveniently clean
any dirt or grease which may collect while searching for leaks.
FEATURES:
• Microprocessor controlled sensor electronics utilizing a multichannel signal detection method improves sensitivity while
reducing false alarms.
• New E_MOS™ sensor technology incorporates a proprietary
pulse modulation design to increase both battery and sensor
life.
• Software managed sensor rejuvenation mode, initiated at
each startup ensures the highest level of sensitivity every
use, for up to 500 hours of detecting leaks of less than .1 oz
per year.
• Sensitivity remains constant over the life of the sensor.
• Meets all US and International standards for automotive use
including SAE J2913 for HFO-1234yf, SAE J2791 for R-134a
and European Standard EN14624:2005. Superior sensitivity
to all HFC, HCFC, and CFC gases and blends as well as SF6.
• 50 hour battery life (3) "C" batteries. Auto Off after 10
minutes. Green LED low battery indicator.
• 500 hours sensor life.
• 2 year warranty excluding batteries and sensor.
• Both visual and audible leak indicators.
• Patent Pending.

OPERATION
Using the LDA1000H
Turning the instrument ON:
Press the red START button once to turn the unit ON. The
instrument 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 6 manually selectable settings, 3 for the
R-134a mode—L, M and S—indicated by blue LED's, and 3 for
the HFO-1234yf mode—L, M and S—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 more puts the
instrument in the lowest sensitivity setting of the HFO-1234yf
mode. 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 HFO1234yf, use the R-134a mode of the LDA1000H.
Turning the instrument OFF:
At any time during operation, press and hold down the yellow
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 (
) will turn off.
Windy conditions:
Locating leaks under windy conditions may severely impede the
leak searching process. Even very large leaks may be difficult
to locate as the escaping gas is quickly dissipated into the
atmosphere. If necessary, fabricate a gas trap using aluminum
foil around joints or fittings or otherwise shield the search area
from the wind.
Leak verification:
If a suspected leak is indicated, verify several times by moving
the sensor away from the leak area, resetting the unit and then
back to the suspected leak. If the instrument indicates a leak
three consecutive times, then you have found a leak.

OPERATION
Searching For Leaks
The LDA1000H features automatic tuning out of background
contamination and needs only to be turned on to begin leak
searching. All necessary sensitivity and calibration settings
are selected by the unit’s advanced control software providing
optimal leak finding performance under any condition.
It is recommended to follow the guidelines stated in SAE J1628
latest release. The basic steps are outlined below.
1. With the system OFF, pressurize it by charging with enough
refrigerant to attain a pressure of at least 350 KPa (50 PSIG).
2. Take care not to plug the sensor housing tip by dragging it
over dirty or wet surfaces. If the area is particularly dirty, or
condensate (moisture) is present, it should be wiped off with
a dry shop towel. Consult the list of substances to which the
LDA1000H may react on page 7. If any of these substances is
present, clean with a dry cloth.
3. Visually trace the entire refrigerant system and look for signs
of air conditioning lubricant leakage, damage, and corrosion
on all lines, hoses, and components. Each questionable area
should be carefully checked with the detector: controls,
service ports with caps in place, brazed or welded areas, and
areas around attachment points and hold-down on lines and
components.
4. Turn on the LDA1000H and allow it to warm up outside the area
to be searched. Based on an estimate of the system’s leak rate,
set the LDA1000H to the appropriate refrigerant and sensitivity
setting. The LDA1000H provides sensitivity settings of 14 g / yr
(0.5 oz / yr) , 7 g / yr (0.25 oz / yr) and 4 g / yr (0.15 oz / yr)
corresponding to the L, M and S marked LED's. If the detector
alarms when the area to be searched is approached, ventilate
the area to eliminate any accumulation of regrigerant which
may obscure the smaller leaks.
5. Always follow the refrigerant system around in a continuous
path so that no areas of potential leaks are missed. If a leak is
found, always continue to test the remainder of the system.
6. At each area checked, the probe should be moved around
the location at a rate no more than 3 in / sec. (75mm / sec.),
and no more than 3/8" (9.5mm) from the surface, completely
around the position. Slower and closer movement of the
probe greatly improves the likelihood of finding a leak.
7. An apparent leak shall be verified at least once by blowing
shop air into the area of the suspected leak and repeating
the check of the area. In cases of very large leaks, blowing
out the area with shop air often helps locate the exact position
of the leak. Also, setting the LDA1000H to the next lower
sensitivity range if the indication is very strong on the bar
graph display or to the next higher sensitivity if the indication
is less than 2 bars in the bar-graph display may help pin point
the leak.

OPERATION
8. When testing for a leak at the compressor, move the probe
along the compressor body joints, along the pressure relief
valve and any switches, the all around the compressor shaft
seal area. Shaft seal normally leak during compressor
operation so it may be very difficult to ascertain if a leak exists
because the testing with an electronic leak detector is
performed with the system off. However, any indication from
the LDA1000H in a setting below the 14 g / yr. (0.5 oz / yr.) may
be an indication that a significant leak has been found,
especially if no other leaks have been located.
9. Following any service to the refrigerant system, and any other
service that disturbs the refrigerant system, a leak test of the
repair and of the service ports of the refrigerant system should
be done.

OPERATION
Maintenance
With a sensor life of more than 500 hours and a battery life of
over 50 hours, very little maintenance is required to keep the
LDA1000H in top operating conditions. Below are the proper
procedures to follow when changing batteries and sensors.
Low battery indication:
When the batteries reach approximately 10% of capacity, the
green LED next to the symbol ( ) will turn off. To replace the
batteries, slide the bottom cover of the instrument backwards to
reveal the battery compartment. Replace the batteries with a new
set of (3) size "C" alkaline batteries.
Changing the E_MOS™ sensor:
See page 9 for the sensor replacement diagram.
• Remove the E_MOS™ sensor housing tip by turning it
counterclockwise.
• With a pair of tweezers or a needle nose pair of pliers gently
pull the E_MOS™ sensor away from its socket.
• Inspect the inside of the sensor housing and verify that there
is an O-ring over the socket and that no dirt or debris is
present. If there is dirt or debris, gently pull the O-ring out, use
a dry cotton swab to loosen the dirt and blow with compressed
air. Clean the O-ring and replace.
Do not cover the O-ring with Vaseline or any other
lubricant.
• Install the replacement E-MOS sensor. Orient the tab on the
edge of the sensor so it coincides with the slot on the side of
the housing and gently push the
Do not use silicone based hand cleaners or lotions prior
to installing a new sensor as this will irreversibly affect
the operation of the sensor.
• Remove and discard the filter inside the sensor housing’s tip.
Replace with a new filter disk, making sure no dirt, water, oil
or any other substance comes in contact with filter. It is
recommended to first clean the sensor housing’s tip with
alcohol or some other solvent which does not contain oil or
silicone. Use a cotton swab to first loosen any debris from the
tip’s opening. Finish by blowing with dry, oil-free, compressed
air. Re-attach the tip to the sensor housing, screwing it finger
tight.
Do not use acetone or silicone based solvents, lotions or
un-cured adhesives while handling the E_MOS™ sensor.
