Sensit Gold G2

Question 1

Sensitivity

Answer 1

1 ppm to 100% by volume

Question 2

What gas is Sensit Gold G2 calibrated to?

Answer 2

Natural Gas

Question 3

How does the auto scale work?

Answer 3

It automatically increases from:

Ppm to %LEL to % by volume (concentrations above 100% LEL)

Question 4

When is “tick” mode used?

Answer 4

To determine leak source

Question 5

Natural gas qualities

Answer 5

Primarily methane
Lighter than air
LEL: 5.3%
UEL: 14%

Question 6

What is Sensit calibrated to?

Answer 6

Methane, so reading require no conversion

Question 7

Sensit Vs Altair

Answer 7

Sensit is calibrated to methane and does not require a conversion vs Altair requires conversion of double to read natural gas accurately

Sensit has greater resolution: 1 ppm vs 1% LEL of Altair

Sensit reads above UEL (14%) vs Altair will not

Question 8

When to use Sensit?

Answer 8

High IOS Natural gas involvement

Quantifies natural gas and locates leaks in TICK mode

Question 9

When to use Altair 5x

Answer 9

CO Alarms
Unknown odors
Confined space
Natural gas with Sensit

Question 10

Sensit Color scaling

Answer 10

Green = <1% of LEL
Yellow = 1% of LEL to 100% LEL
Red = >100% LEL

Yellow reads as how close to LEL gas is in the atmosphere

RED reads as % by volume in atmosphere

Question 11

When calibrating the Sensit with 2.5% calibration gas what are the readings it will give you?

Answer 11

25,000 ppm = 50% LEL = 2.5% volume

Question 12

When calibrating the Sensit with 100% methane gas what are the readings it will give you?

Answer 12

It will scale up from ppm to %LEL to % by volume

Question 13

When the Sensit reads 10% LEL what does the Altair 5-gas read? Why?

Answer 13

Altair 5 gas reads 20% LEL because of the .5 correction factor

Question 14

What does button A do?

Answer 14

Operates power, mute feature, and exit menu items

Question 15

What does B button do?

Answer 15

Operates the tick rate control, enters, changes, selects menu items

Question 16

What does button C do?

Answer 16

Save data feature, manually zero sensors, scroll and change menu items

Question 17

What does a green LED indicate

Answer 17

Ready

0-4.9% LEL Methane

Question 18

What does an amber LED indicate?

Answer 18

Low

5% to 9.9% LEL Methane

Question 19

What does a red LED indicate?

Answer 19

Haz 1-3

> 10% LEL methane

Question 20

Where should you start the Sensit G2?

Answer 20

In a gas free environment

Question 21

What should you do if “pump blocked” is not displayed when performing a pump check?

Answer 21

Replace the rubber O-rings at the sampling tip

Question 22

How do you put Sensit G2 into tick mode?

Answer 22

Press tick menu button

then “select test tick” will be displayed

Press Tick menu again

Equipment is in tick mode

Question 23

How do you re-enable ticks if you have muted it?

Answer 23

Press tick/menu button

Question 24

How does the Sensit Gold G2 indicate concentrations of gas?

Answer 24

Bar graph will be displayed and audible clicks will increase as concentrations increase

Question 25

What is displayed if Sensit Gold G2 encounters a gas it is not calibrated to?

Answer 25

Equipment displays:

NSR (nonstandard response)

NSC (nonstandard combustible)

If you encounter these consider backing out and reevaluating the situation
