MiniRae 3000 PID Flashcards
What type of batteries does it take and how many?
It takes 4 AA batteries
How long will it operate with full battery life?
12 hours
What is the response time?
2 seconds
What kind of lamp do we use?
10.6 eV. Our lamp will not read anything with an IP above that.
What is the range?
0.1-15,000 ppm
What does the PID detect? What does it measure in?
Volatile Organic Compounds. Anything with carbon in it. Measures toxicity in ppm. Does not detect LEL
What modes can the PID operate in and which one do we use?
Hygiene mode and Search. We use hygiene.
Explain how both modes work.
Hygiene- Continuous monitoring
Search- Starts and stops manually by pressing mode (middle) button
How many gases are in the library?
Over 200
What are the ways to calibrate the PID?
Zero Cal- Using zero gas or a fresh air environment
Span Cal- 100ppm Iso bottle
What is the PID calibrated to?
Isobutylene
How many CCs of air should the pump draw?
450-550 cc/min
How many feet will the pump draw?
Horizontally: 200 ft
Vertically: 90 ft
or 100’
How many feet per second will the pump draw?
3 ft/s
How many seconds does calibration take?
60 seconds
What does it mean if you see the bottle symbol on the screen?
Calibration needed. Dark icon indicates that calibration should be performed; light icon indicates bump should be performed
What does it mean when the pump symbol is flashing with an X?
The pump has failed or something is obstructing the pump.
What are the alarm levels?
High- 100ppm
Low- 50ppm
TWA- 100ppm
STEL- 50ppm
What forms of data logging are there?
Auto- continuous logging
Manual- must press mode to start and stop
Snapshot- takes shot of that one reading
What does it mean if you have high readings? How do you fix it?
Dirty filter, dirty sensor, moisture, incorrect calibration
Clean or replace filter or sensor, blow dry sensor, calibrate unit
What does it mean if you have low readings? How do you fix it?
Dirty filter, weak lamp, dirty sensor, hole in probe
Replace sensor or filter, replace lamp, check for a leak.
What is the operating temperature range?
-4 to 122 degrees F
(-20 to 50 degrees C)
How do you access the library?
Holding the “Mode” and “N/-“ button
How many ppm is equal to 1% of the LEL?
10,000ppm
What setting do we use for data selection?
Average
What data log type do we use?
Auto
What alarm modes are there and what do we use?
There is auto reset and latching. We use auto reset
Auto reset
Latching
Which user mode do we use?
Advanced. Gives us access to more features
What pump speed do we use?
High
What percent is the pump duty cycle?
100%
How long are the data logging intervals?
60 seconds
What will you see during duty cycling (PID lamp cleaning)?
The pump symbol will alternate between showing an inflow of air and and the pump with a blinking X
When is calibration required?
- 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
When is a bump test required?
- When the calibration symbol is light and blinking
- If the sensor has failed a previous bump test
- Before each use
What does the check mark icon mean?
That the instrument has been bumped and calibrated in compliance with the policy settings
