How do you get into background mode?

Answer 7

Quickly press “peak” button 4 times while in high sensitivity mode

Question 8

What does background mode do?

Answer 8

• Pin points leaks (most sensitive operating mode)
• instrument will trigger on extremely small refrigerant levels and sudden movements
• This fourth sensitivity mode eliminates high backgrounds

How long does the warm up/calibration sequence take?

Answer 9

30 seconds

Question 10

What is the default sensitivity level?

Answer 10

High

Question 11

What sensitivity level should you use for a large leak?

Answer 11

Medium or low

Question 12

Does this meter require calibration?

Answer 12

No, it auto adjusts to ambient conditions of an area that may have background refrigerant gases present

Question 13

What types of refrigerant does this detect?

Answer 13

CFCs, HFCs, HCFC blends, and HFO-1234YF in HVAC/R applications

Question 14

What is the sensitivity?

Answer 14

<0.1 oz/yr (3 g/yr)

Question 15

What four operating modes does it have?

Answer 15

• Low
• Medium
• High (default)
• Background mode (most sensitive)

Question 16

Is it ok to draw moisture through the probe?

Answer 16

No

Question 17

What is the max temp a battery can be exposed to?

Answer 17

140 ° F

Question 18

What type of detector is this?

Answer 18

Locating Leak Detector (Type C)

Question 19

how long does it take for the battery to recharge?

Answer 19

3 hours

Question 20

What is the response time, recovery time, and zeroing time?

Answer 20

< 1 sec
< 2 sec
< 2 sec

Question 21

What are the fixed probe (static) detection limits?

Answer 21

Upper- None (> 50 g/yr)
Lower- 0.5 g/yr (0.02 oz/yr)

Question 22

What are the moving probe (dynamic) limits?

Answer 22

Upper- None (> 50 g/yr)
Lower- 1.0 g/yr (0.04 oz/yr)

Question 23

What is the lower detection limit for contamination?

Answer 23

3.5 g/yr (0.12 oz/yr)

Question 24

What does it mean if the LOW-BATT LED is blinking?

Answer 24

The battery is charging

Question 25

What does it mean if the LOW-BATT LED is solid?

Answer 25

The battery is low

Question 26

How do you change the sensitivity mode?

Answer 26

Pressing the L/M/H button

Question 27

As a rule of thumb, how should the sensitivity be set?

Answer 27

The higher the background concentration of refrigerant in the air, the lower the sensitivity level should be set

Question 28

What does the peak function do?

Answer 28

Stores the highest change in refrigerant concentration achieved while continually detecting leaks

Question 29

What happens when you turn the Peak function on or off?

Answer 29

- On: LED illuminates - Off: Peak information is cleared

Question 30

When background mode is on, what color will the LED be?

Answer 30

Left most bar will quickly flash green

Question 31

What colors do the LED bars display?

Answer 31

The eight LED bars display green, amber, and red

Question 32

How small of a leak can High sensitivity mode detect?

Answer 32

As low as 0.1 oz/yr (3 g/yr)

Question 33

When should you retest a leak?

Answer 33

When a leak is discovered using the most sensitive settings or if the probe was in a static position

Question 34

What noise will the meter make in background mode?

Answer 34

It will go from a tick to a steady tone

Question 35

How long is the probe and extension?

Answer 35

15" flexible probe 9" extension

Question 36

What should be used between the probe, the tip, and any extensions?

Answer 36

An O-ring

Question 37

Does the meter detect absolute concentration of refrigerant?

Answer 37

No, only changes in concentration levels

Question 38

How long can it take the meter to clear after detecting a small amount of refrigerant?

Answer 38

Up to 30 seconds but typically no more than 2-15 seconds.

Question 39

Where would you most likely detect a leak?

Answer 39

- Soldered joints in refrigerant lines - Points with changes in cross sections - Points with changes in direction of lines

Question 40

What should you do with the probe when detecting a leak?

Answer 40

Slowly sweep back and forth no more than .25" from suspected leak areas (3in/sec)

Question 41

If a leak is found what should you do?

Answer 41

Continue to test the remainder of the refrigerant system

Question 42

Should you use commercially available canned air to clear an area of refrigerant build up?

Answer 42

No because it uses refrigerant too

Question 43

Where is the filter located?

Answer 43

The tip of the wand

Question 44

What happens if the filter gets wet?

Answer 44

It restricts the flow of air and must be replaced
