Operation
On the operator level (OPERATOR LEVEL) a variety of administration functions for the data and the memory
are available. The basic functions like
“Start print out”, “Open new test specimen dataset” and “Erase data
memory” can be invoked also through the buttons of the handset.
In contrast to earlier versions of the P1:p leak detectors, the data is not automatically deleted after a
successful print out. Instead the data is retained until being deleted manually. The operator should, for this
reason, before starting a new measurement run, not forget to delete the “old” data.
In each test specimen dataset the following information is also saved besides the actual measurement data:
- The serial number of the leak detector
- The unit of measurement selected for the display at the point of time of the measurement
- The type of gas (SF6 or FM-200) selected at the point of time of the measurement
- Creation time and date for the test specimen dataset
- Optionally, a worker identifier
- Optionally, a test specimen identifier, serial or batch number, for example
- The leak rate limit applicable when taking the measurement
- The total of all saved measured values (total leak rate).
For each individual measured value, the time of the measurement as well as any apparent exceeding of the
limit are also printed out.
The output is effected in the text format through the serial interface. If instead of a printer, a computer is to
receive the data, then a so-called Null Modem Cable must be used where the signal lines are crossed. The
transmission format is 9600-8-N-1 (9600 baud, 8 data bits, no parity, 1 stop bit). When using a printer, the
leak detector must be set up for the same handshake as used by the printer (0 Handshake ), so that the
printer can control the data flow. For this please also refer to the manual of your printer.
On the supervisor level (SUPERVISOR LEVEL) the entry of a worker or test specimen identifier can be
made mandatory. When such entries have been made mandatory, the instrument will query the entries upon
opening a new test specimen dataset. Also if such entries are not made mandatory, such entries can be
entered at any time, however, the operator is not asked to do so. The information relating to the
identification, needs to be entered BEFORE creating the test specimen dataset in which it shall appear.
Possible malfunctions when starting the system
Most severe errors are already detected and indicated upon switching the instrument on. Running up of the
instrument is then interrupted and a corresponding error message is indicated. At the bottom of the screen, a
countdown will run which switches the instrument off after 15 seconds. This countdown can be cancelled
through the [ STOP ] button. After operating this button, its designation changes to [ EXIT ] allowing the
operator to enter the menu system where he may then change settings, read out technical data or run a
diagnosis.
Inasmuch as the displayed message is not self-explanatory, please get in touch with ISM or your ISM
certified distributor stating the kind of error message so as to allow the malfunction to be analysed. If an error
message relating to the SmartSensor is encountered, please always first exchange the SmartSensor.
Possible malfunctions during operation
If during operation a relevant malfunction occurs, the display on the handset will change from “READY” to
“NOT READY”, and the “MESSAGE” lamp will light up indicating to the operator to read the error message
displayed on the screen and if required acknowledge it.
