6-24
The next byte indicates whether this PQ record is continuous in monitoring with the previous
record. If the byte is non-zero, then this is the first record recorded after a power-down, reset or
download, and all unfinished durations prior to this record are lost. If the byte is zero, then
monitoring was continuous between the last record and this one.
The next 22 bytes are the RMS Gain Factors. Following is the order of these factors:

transitions of Internal and External Digital Inputs.
Q
Record Format: A Record contains 16 Bytes.
The first eight bytes in each record is the Time Stamp, representing the time of the event the
record is recording. The format of the Time Stamp is:
Byte Format Range Description
0 binary 0 - 99 century
1 binary 0 - 99 year
2 binary 1 - 12 month
3 binary 1 - 31 day
4 binary 0 - 23 hour
5 binary 0 - 59 minute
6 binary 0 - 59 second
7 binary 0 - 100 centisecond
Note: This log does not record records during Test Mode.
An additional piece of information is contained in the centisecond byte.The most significant bit indicates
whether this Digital Input record is contiguous in monitoring with the previous record. If the bit is 1,
