Rigel Medical has introduced a new high performance Electrosurgical Analyser with the emphasis on speed and ease of testing all modern day Electrosurgical devices. The new Rigel 377 utilises a new approach to measuring the high frequency leakage, power distribution and remote plate security testing, ensuring high accuracy and the widest range of built-in resistors. Full colour screen and rotary ensure navigation make the Rigel 377 easy to operate and can provide step by step help to ensure the correct connection to the device under test.
The new Rigel 377 incorporates a range of custom settings that include a variety of test sequences and power distribution curves which make testing fast, easy and accurate. Utilising the large full colour display, built-in memory and data management facilities, the Rigel 377 is the first fully stand-alone diathermy tester that can offer true user friendly operation and operator safety. The large array of internal resistors, ranging from 10-5100Ω in 10Ω steps provide not only the most accurate and detailed power curves, the Rigel 377 also advocates safe working practise by providing all necessary resistors within the enclosure.
The remote electrode monitoring test offers a unique isolated and electronically driven potentiometer to provide accurate and fast testing of alarms. In addition, the Bluetooth-enabled technology allows the wireless connectivity of the tester with PCs and other accessory equipment for fast and convenient downloading of performance data and the uploading of manufacturers’ power curves and manufacturer specific test programs.
Other special features of the Rigel 377 include in-built graphics to display connection diagrams, program settings, power curves, alarm settings, data management and data analyses.
Custom Test Settings
The unique colour user-interface provides both graphic as well as numeric representation of the test data. Showing manufacturer specific curves and allowable tolerances, the large colour screen provides instant performance indication.
Use the graphic representation to quickly determine whether the test data meets the set criteria.
Use the numeric representation of the data to analyse parameters such as Peak voltage, crest factor, power and current at each resistance point etc.
Remote Electrode Monitoring
Use the rotary encoder to set high and low alarm points as well as controlling the potentiometer, scaling up or down in manual or automatic mode. Then, simply capture the alarm using the dedicated fast key on the screen.
Data will be stored onboard for future traceability.
HF Leakage
Individual settings can be selected using the simple configuration template. The settings are automatically translated into a detailed scheme as shown below;
Detailed instructions on the leakage path and connections between each setting are provided in a clear and colour coded overview.
Colour coded connections correspond to the matching connection on the tester.
Applications:
To verify the correct performance of Electrosurgical devices during:
a. Routine testing
b. Type testing
c. Production line testing
Unique training tool for testing on Electrosurgical devices
