Credit Balance = [(Coins IN + Banknotes IN + Cashless IN + Total WINS) - (Coins OUT + Cancel Credits + Cashless OUT + Turnover)]%2^32
Where: % is the modulus operator (to handle meter roll over).
Note: The cases of a ‘meter roll-over’ should be taken into account when performing a “Self Audit” check. In the case of decimal meters, the modulus is 10^10.
Occurrence of Self Audit Check
3.3.19
The self audit check shall be performed at least at the following times:
a) At the start of every play.
b) Before commencing any process that transfers any monetary value out of the gaming machine (e.g. hopper pay, cancel credit/ticket pay or credit transfer out).
Action on Failure of Self Audit Check
3.3.20
The EGM shall enter an Unrecoverable Memory Corruption state in the event that this self audit check fails.
Meter Increment Test
3.3.19a At the end of each play, the value of the following master meters must be compared to value of the same master meter at the end of the previous play :
Master Meter Increment Threshold
COINS IN $1,000
BANKNOTES IN $10,000
If the change in the value of the master meter is greater than or equal to the increment threshold, the gaming machine must register a fault event and display the error message ‘Excessive Meter Increment’ (see also Table 3-6 and Section 3.16.3 Gaming Machine Faults).
Progressive Meters
3.3.21

|---|---|---|
| CURRENT VALUE | current prize amount | [$,] |
| OVERFLOW | amount exceeding ceiling | [$,] |
| HITS | number of hits for this progressive | [count] |
| WINS | total value of wins for this progressive | [$,] |
| STARTUP | startup value | [$,] |
| CEILING | ceiling value | [$,] |
| INCREMENT | percentage increment rate | [%] |
| HIDDEN INCREMENT | percentage increment rate for the reserve pool | [%] |
| INITIAL | VALUE initially entered after last RAM clear. (Used for creating a ‘lost’ jackpot.) | [$,] |
