16
Q

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

A

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

17
Q

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

A

The pump has failed or something is obstructing the pump.

18
Q

What are the alarm levels?

A

High- 100ppm

Low- 50ppm

TWA- 100ppm

STEL- 50ppm

19
Q

What forms of data logging are there?

A

Auto- continuous logging

Manual- must press mode to start and stop

Snapshot- takes shot of that one reading

20
Q

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

A

Dirty filter, dirty sensor, moisture, incorrect calibration

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

21
Q

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

A

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

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

22
Q

What is the operating temperature range?

A

-4 to 122 degrees F

(-20 to 50 degrees C)

23
Q

How do you access the library?

A

Holding the “Mode” and “N/-“ button

24
Q

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

A

10,000ppm

25
Q

What setting do we use for data selection?

A

Average

26
Q

What data log type do we use?

A

Auto

27
Q

What alarm modes are there and what do we use?

A

There is auto reset and latching. We use auto reset

Auto reset

Latching

28
Q

Which user mode do we use?

A

Advanced. Gives us access to more features

29
Q

What pump speed do we use?

A

High

30
Q

What percent is the pump duty cycle?

A

100%

31
Q

How long are the data logging intervals?

A

60 seconds

32
Q

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

A

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

33
Q

When is calibration required?

A
  • 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
34
Q

When is a bump test required?

A
  • When the calibration symbol is light and blinking
  • If the sensor has failed a previous bump test
  • Before each use
35
Q

What does the check mark icon mean?

A

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