How long will it operate with full battery life?

Answer 2

12 hours

Question 3

What is the response time?

Answer 3

2 seconds

Question 4

What kind of lamp do we use?

Answer 4

10.6 eV. Our lamp will not read anything with an IP above that.

Question 5

What is the range?

Answer 5

0.1-15,000 ppm

Question 6

What does the PID detect? What does it measure in?

Answer 6

Volatile Organic Compounds. Anything with carbon in it. Measures toxicity in ppm. Does not detect LEL

Question 7

What modes can the PID operate in and which one do we use?

Answer 7

Hygiene mode and Search. We use hygiene.

Question 8

Explain how both modes work.

Answer 8

Hygiene- Continuous monitoring

Search- Starts and stops manually by pressing mode (middle) button

Question 9

How many gases are in the library?

Answer 9

Over 200

Question 10

What are the ways to calibrate the PID?

Answer 10

Zero Cal- Using zero gas or a fresh air environment

Span Cal- 100ppm Iso bottle

Question 11

What is the PID calibrated to?

Answer 11

Isobutylene

Question 12

How many CCs of air should the pump draw?

Answer 12

450-550 cc/min

Question 13

How many feet will the pump draw?

Answer 13

Horizontally: 200 ft

Vertically: 90 ft

or 100’

Question 14

How many feet per second will the pump draw?

Answer 14

3 ft/s

Question 15

How many seconds does calibration take?

Answer 15

60 seconds

Question 16

What does it mean if you see the bottle symbol on the screen?

Answer 16

Calibration needed. Dark icon indicates that calibration should be performed; light icon indicates bump should be performed

Question 17

What does it mean when the pump symbol is flashing with an X?

Answer 17

The pump has failed or something is obstructing the pump.

Question 18

What are the alarm levels?

Answer 18

High- 100ppm

Low- 50ppm

TWA- 100ppm

STEL- 50ppm

Question 19

What forms of data logging are there?

Answer 19

Auto- continuous logging

Manual- must press mode to start and stop

Snapshot- takes shot of that one reading

Question 20

What does it mean if you have high readings? How do you fix it?

Answer 20

Dirty filter, dirty sensor, moisture, incorrect calibration

Clean or replace filter or sensor, blow dry sensor, calibrate unit

Question 21

What does it mean if you have low readings? How do you fix it?

Answer 21

Dirty filter, weak lamp, dirty sensor, hole in probe

Replace sensor or filter, replace lamp, check for a leak.

Question 22

What is the operating temperature range?

Answer 22

-4 to 122 degrees F

(-20 to 50 degrees C)

Question 23

How do you access the library?

Answer 23

Holding the “Mode” and “N/-“ button

Question 24

How many ppm is equal to 1% of the LEL?

Answer 24

10,000ppm

Question 25

What setting do we use for data selection?

Answer 25

Average

Question 26

What data log type do we use?

Answer 26

Auto

Question 27

What alarm modes are there and what do we use?

Answer 27

There is auto reset and latching. We use auto reset Auto reset Latching

Question 28

Which user mode do we use?

Answer 28

Advanced. Gives us access to more features

Question 29

What pump speed do we use?

Answer 29

High

Question 30

What percent is the pump duty cycle?

Answer 30

100%

Question 31

How long are the data logging intervals?

Answer 31

60 seconds

Question 32

What will you see during duty cycling (PID lamp cleaning)?

Answer 32

The pump symbol will alternate between showing an inflow of air and and the pump with a blinking X

Question 33

When is calibration required?

Answer 33

- When the calibration symbol is dark and blinking - If the calibration gas is changed - If it has been 30 days or more since calibration - If the sensor has been changed - If the lamp has been changed

Question 34

When is a bump test required?

Answer 34

- When the calibration symbol is light and blinking - If the sensor has failed a previous bump test - Before each use

Question 35

What does the check mark icon mean?

Answer 35

That the instrument has been bumped and calibrated in compliance with the policy settings
