Rigel 377 Instruction Manual – Version 1.0 - 7 -
1. Introduction
The Rigel 377 Electrosurgical Analyser is a versatile bench-mounted yet portable tool,
for testing the performance of electrosurgical equipment.
Utilising a large, full colour graphical display, the Rigel 377 is the first fully stand-alone
electrosurgical analyser that can offer true intuitive, user friendly operation and operator
safety.
1.1. Analyser Functions
The Rigel 377 Electrosurgical Analyser enables biomedical engineers to efficiently
analyse the output of electrosurgical diathermy machines. The RF signal input is
simultaneously digitally analysed to provide all the characteristics of interest: Watts,
current, peak Voltage, crest factor. The Rigel 377 can also produce load/ power curves
automatically analysing the load/power performance of an electrosurgical diathermy
machine.
The Rigel 377 is able to measure the following parameters manually;
1. Power
2. HF Leakage
3. Plate Security (REM, Remote Electrode Monitoring)
For the power test, an internal array of resistors provide a safe variable load of 10-
5100Ωin 10Ωsteps; enabling the production of accurate and detailed power distribution
curves, with an instant tabular view of test results.
A unique feature of the HF leakage test is on screen graphics illustrating correct test
connection configurations, complete with user set pass fail limits.
The plate security (REM) test offers a unique isolated, electronically driven
potentiometer, which provides a continuous swept resistance change; enabling
accurate and fast testing of alarms, complete with user set pass fail limits.
Any future firmware upgrades can be efficently installed by users, without risk to stored
data.
The new Rigel 377 forms part of a comprehensive range of high performance specialist
biomedical test equipment supplied by Rigel Medical, part of the Seaward Group.
