FAQ Answers                                                                                      

1C. Standard calibration means that the calibration method is a company internal standard procedure. In many case, if the company received a quality certification (e.g. ISO 9001:2000), this procedure is being certificated by the certification agency. 

SIT calibration means that the calibration procedure is the official SIT method, that offers the best possible calibration today. Generally this kind of calibration is requested only if there is a precise specification for it.

2C. There is not a predefined calibration interval. Often the time between two calibration depends on how much and under wich conditions the equipment is being used (e.g. lab or field use).

Generally a good calibration interval is 2 years, but for specific applications it could be necessary to calibrate every 12 months. Contact us for more details.

3C. The time for a calibration is generally around 20 days from the shipping day. Booking the calibration in advance can be useful to shorten this time. 

4C. The best solution is to ask for the "MPB" standard calibration service, that includes a replacing equipment during all the time needed to complete the calibration service

5C.

1P. The first thing to do is always "check the cable" that means verify every connection. Then you have to verify, in the the PMM 8053 settings panel, that the right "serial" is choosen ("optical" if you use an optical fiber and "serial" if you use the RS232 link).

Then check that the right "port" is specified to the software. You can specify the port by right clicking on the PMM 8053-SW02 icon on your PC and choosing "properties"; right after the filename line add a blank space and then "COMM=n" to force the software to use that exact port. If you cannot establish the connection yet then contact us for further support. 

2P. You can find a table reporting the various EHP50 logger configuration and the relative expected autonomy on the PMM 8053 user manual (page 8-6).

3P. You can ask for a battery replacement on your instrument, but we strongly recommend to calibrate it, because the calibration already includes a complete battery pack substitution.

4P. The PMM 8053 probes are compatibiles only with the PMM 8055 monitoring station. The PMM 8057 monitoring station uses new digital probes, so its impossible to connect the old  probes on it.

5P. The only way to obtain such a configuration is by connecting the probe via the optical repeater PMM OR03. You can find more details in the PMM 8053 datasheet, page 7. (dowload it here)
