RMCS PC Software

Radwag Multiple Comparator Software, RMCS, has been designed to enable management of laboratory-performed calibration procedures, starting from the moment of accepting an order, through its progress, until issuing a calibration certificate.

The calibration process supported by means of RMCS provides improved efficiency, reliable measurement results and complete documentation on calibration process, together with lower labour costs.

RMCS PC Software is intended for cooperation with RADWAG manufactured mass comparators. With the software you can carry out calibration processes using ABBA and ABA methods.

RMCS PC software makes it possible to initiate the calibration procedure by means of task sent to a particular mass comparator. Additionally it features option for autonomous performance of calibration process, triggered by the mass comparator itself. In both cases, data is transferred to the software for the purpose of registering, controlling and finally issuing a calibration certificate.

RMCS System functions

1. Complete management of a calibration laboratory calibrating mass standards and weights
2. Complex management of RADWAG comparators
3. Calibration using ABBA and ABA methods
4. Cooperation with monitoring system for ambient conditions
5. Databases support: comparators, mass standards, users and calibration orders
6. Bilateral data synchronization with RADWAG mass comparators
7. Archiving orders, calibration certificates and ambient conditions records
8. Record of events and calibration process reporting

Export of report results and calibration certificates.

Mass comparators linked in the RMCS system autonomously cooperate with THB ambient conditions modules recording ambient conditions state (temperature, humidity and atmospheric pressure) throughout the whole control process. Measurement results are displayed and sent, in real time, to RMCS software for the purpose of process control and data archiving.

Ambient Conditions Monitoring THB

Maintaining optimal ambient conditions at a workplace is a warranty of precise results for comparison processes.

THB monitoring system has been designed to offer option of constant ambient conditions supervision provided at the place of mass comparator operation or in any laboratory room. The system performs real-time measurement of air temperature, relative humidity and atmospheric pressure. The measured values are then used for calculation of air density and dew point temperature.

The measurements carried out for particular workstation are performed by means of its local sensors – THB Ambient Conditions Modules. Current state of given measurements is displayed on the comparators terminal along with messages informing on critical values, all this thanks to connection established between the THB module and the comparator.

Measurements results of particular THB modules are transferred in real time to THB-R recorder. The recorder supports up to 16 modular sensors, thus allowing monitoring of ambient conditions in multiple points in the proximity of up to 1200 m. THB-Multi software enables displaying the measurements results on the computer screen. Additionally it offers data analysis, reports and charts preparation and measurements record in database.

Basic parameters for THB Ambient Conditions Modules

• Measured temperature range +5°C – +45°C
• Temperature measurement accuracy d=0,01°C / error ± 0,1°C
• Measured pressure range 850 – 1050 hPa
• Pressure measurement accuracy d=0,1 hPa / error ± 2hPa
• Measured humidity range 0 – 100%
• Humidity measurement accuracy d=0,1% / error ± 2%
• (from 0% to 10% and from 90% to 100% the accuracy is 5%)
