OZONE MONITOR BMT 932 Manual, Rev. 02/2021

Any failure including the warning states mentioned above, and any electric failure will activate the

ERROR/WARMUP warning signal; even power down is signalled by the error relay coupled

with the failure warning.

The OZONE MONITOR BMT 932 features a "Sniffer Mode" which suppresses the zero cycle.

This mode which can be used for easy ozone leak detection.

The instrument has a built-in clock with calendar, which is used to provide time stamps for an

Event-Log (103 entries, e.g. power on/off, alarms) and an Error-Log (16 entries, e.g. Overrange,

Low Flow). These logs can be read out and printed via the serial interface with the mentioned

software BMT 932 Link. A "Relay Box" built into the OZONE MONITOR BMT 932 is availa-

ble to offer electric contacts for each threshold, low and high, of each sample channel, see Ap-

pendix R.
