FORMULA® R Test System
The FORMULA® R Test System is an automated test and measuring system designed for comprehensive automated verification of the low-current DC electromagnetic relays with up to 8 coils and up to 12 contact groups.
The applications of the Test System are quality control of all stages of the relay lifecycle, including:
- testing and research of newly developed relay types in diagnostic modes
- Modes close to real conditions of relay operation in productsfactory acceptance and in-production testing in serial production: qualification, periodic, approval and stress testing
- certification testing
- analysis of deviations and failure prediction
- incoming inspection
The FORMULA® R meets the requirements of the metrological standards for measurements and tests in microelectronics.
Developer and the manufacturer of the Test Systems:
FORM, Russia
FORMULA® R Test System performs a comprehensive diagnostic control and measurement parameters of the relay in full accordance with MIL-PRF-39016F.
Basic technical characteristics and functional capabilities
The FORMULA® R Test System have been created to provide highly reliable measurements of the parameters of relays.
The key technical characteristics of the Test Systems are defined by the following values:
The Test System is a functionally complete automated tool for measuring a wide range of low-current relays, and provides users with the following advantages:
- High readiness of equipment for measurements and tests
- Automation of all stages of the measurement process and data management
- User-friendly, fully functional software
- Automatic diagnostics and metrological calibration
- Reliability in round-the-clock operations and availability of two workstations
- Ability to work with autoloaders
Wide range of application and continuity
The concept implemented in the FORMULA® R relay Test System provides its effective application in three areas:
- as measuring tools when testing relays in full accordance with MILPRF-39016F
- as a tool for analyzing the causes and mechanisms of relay failures during production
- as a means of predicting the reliability of the relay on tests and the incoming inspection of relay
Technical advantages
The fundamental innovations that are implemented in the Test System, provide the Consumer with the advantages of technical and metrological level, allowing:
- Relay timing parameters
- Contact resistance (resistance of the contact circuit at their closure)
- Pick-up and drop-out voltage/current using step voltage/current change program function
- dielectric withstanding voltage measurements at a voltage up to 800 V (1000 V)
- contact stabilization time and coil EMF measurements
- Identify the latent fault of the relay using a built-in high-resolution oscilloscope and software for testing and research of relays
- Perform failure analysis and prediction of relay reliability using arbitrary cyclograms
- Monitor the electrical parameters of resistor array (customized)
- Measure reed switch with low resistance contacts, short triggering and releasing times and high insulation resistance–up to 10 GΩ
Workplace ergonomics and safety
The Test System test head and the measuring stations for device under test connection are built in a special worktable supplied with the Test System.
The possibility of monitoring electromagnetic relays is provided at one or two measuring stations, with independent monitoring of two different types of relays.

As a matter of convenience, the start buttons on the operator panel are placed under the right and left hand.
In manual measurement mode, operators only work with the «Start» button and display panel that show the «Accept» and «Reject» results.
All testing results are automatically saved in the database of the Test system, as well as in the cloud data base Kamchatka®
The design ensures reliable protection of the high-voltage measurement zone, guaranteeing complete electrical safety for the operator.
For maximum performance and safety, the Test system has a fully automatic measurement mode using autoloaders and environmental chambers.
The test system’s maintainability is provided by its modular design and automated diagnostic tools, both autonomously and via the Internet, to identify test system faulty unit. Diagnostic system and test system design allow to repair the test system in case of failure within 1 day in field.
