MMQ stands for Month/Month/Quarter. It refers to LDAR rules that change a component’s monitoring schedule to a quarterly basis only after not leaking for two consecutive months.
Chateau assigns each of the phases in this MMQ a special M21Why:
|
Term
|
Definition
|
|
M1
|
The first of the two months after a component is initially added.
|
|
m1
|
The first month of requalification monitoring after a leak on an existing component.
|
|
M2
|
The second of the two months after a component is initially added. The first month (M1) must be passing.
|
|
m2
|
The second month of requalification monitoring after a leak on an existing component.
|
|
MMQ
|
The quarterly event that occurs after a passing result on an M2 Inspection.

Note: For newly-tagged databases, if no past inspection records were imported, the components will start in the M1 phase as if they were “brand new.” Please send a request to LDARtools Support to update your MMQ components to the MMQ phase if these are existing components already qualifying for quarterly inspections.
The MMQ Phase is slightly different from the NextM21Why. Chateau defines and maintains the MMQ Phase on any MMQ Component even when the component is not scheduled to be monitored. There are three phases:
- M1 – The first month of monitoring after a component is added to the database, or the first month of requalification monitoring after a leak.
- M2 – The second month after a component has been added and passed inspection, or, the second month of requalification monitoring after a leak.
- MMQ – The quarterly phase when a component is not leaking, requalifying after a leak, or brand new,
For instance: An MMQ Comp is monitored as an MMQ.
- Because it is in the MMQ Phase.
- It Leaks.
- Its Frequency is still MMQ.
- Its Next M21 is BLANK (because it is done for the current period)
- BUT…Chateau changes its MMQ Phase to M1 immediately so you can see on the Home Screen, Component grid, and the Tag View that the leak was recognized and the change has been made.
- The Schedule will not show the m1 scheduled until the first of the next month, but the Home Screen will show the M1 in the MMQ Phase immediately.
There are three different events that will “reset” the MMQ phase to M1:
- A failing M21 inspection
- Component Initialization (when a new equipment model is installed)
- Missed inspection—if the component is currently in the M2 phase.
- If a component is in the mmQ phase, then a missed inspection will NOT reset the phase back to M1. The component will be rescheduled the consecutive month of the quarter. This will continue until the inspection is performed.
MMQ Group controls which month of the quarter the MMQ monitoring is scheduled in.
- Note: MMQ Group edits are not tracked by MOC. You won’t be able to see the past MMQ Group changes in the Historical MOC Porch.
- The setting is a component property that you edit in the Tag View. Most likely you will identify a group of MMQ components and do a Multi-Edit.
You can control when the MMQ Monitoring is done by setting each MMQ component to one of the following groups:
|
|
Means the MMQ monitoring will be performed in…
|
|
Month 1
|
The first month of each quarter.
|
|
Month 2
|
The second month of each quarter.
|
|
Month 3
|
The third month of each quarter.
|
|
None
|
As due at the end of the quarter. The inspection can be performed ANY month of the quarter.

Below are a few component scenarios you will see on the component grid.

If you see this in Component grid, it means…

|

|
M1
|
Month 1
|
M1 Phase. First month of the quarter. Due in the current month.
This component is brand new and has not been monitored for the first time yet. |
| 2 |
MMQ
|
|
M1
|
Month 2
|
M1 Phase. Second month of the quarter. Already done for the current month (which is why the NextM21 is blank).
The NextM21Why will populate when you are in the monitoring period. After some experience, you will see this component must have leaked when it was monitored earlier in the current month. If you can see that, you are an MMQ Guru! |

MMQ
|
m2
|
M2 |
Month 3
|
MMQ phase will be done in the third month of quarter.
This is scheduled for the current month as an m2, which means it was monitored LAST month as an m1 and DID NOT LEAK. Can you see that? |

MMQ
|
|
MMQ |
Month 2
|
MMQ will be done in the second month.
Whether you can see this record means this component was monitored already this month, was not leaking, and has been advanced to or stayed on the MMQ phase? |

Since there is not MMQ Group, MMQ will be due at the end of the quarter.
The inspection can be performed at any point during the quarter. |
