5200 Multi Purpose and 5200 Multi Purpose HF Gas Analysers
05230001A / Revision 956
6.7.3 Introduction to data logging
The Multi Purpose allows you to maintain a data log of sample measurements made,
within the Multi Purpose memory. The data log consists of one or more ‘batches’ of
measurements, and a total of 200 measurements can be stored.
Each sample measurement entered in the log has:
• an associated batch number
• a sequence number of the sample measurement within the batch
• the date and time that the measurement was made
• an alarm indication (if the measurement caused a measurement alarm to be raised)
• a fault indication (if a fault existed at the time of the measurement).
You must manually transfer measurements into the data log, specify when a new
batch is to start within the data log, and clear the data log when necessary.
At any time, you can view the currently stored data log on the Multi Purpose display,
or you can output it to a device (such as a PC) connected to the Multi Purpose serial
output port.
6.7.4 Entering measurement data into the data log
When you want to enter the sample measurement(s) from the Measurement screen
into the data log:
1. Press the soft key. When you press the soft key, the current sample
measurement at the time of the key press is ‘captured’ (stored in internal
memory), and the Data logging screen will then be displayed (see Figure 42).

The Multi Purpose cannot be configured to automatically log data over
specified periods of time. If you require such a facility, we recommend that
you select serial outputs (instead of data logging) and connect the serial
output to a PC or a commercially available data logger.
