Portable Single Channel Igniter Circuit Testers

We make three versions of portable testers.

1. Fail-safe module limits test current. Since excessive test current could cause bodily injury or death, protection for all modes of failure or operator error is built into the squib tester. A sealed, tamperproof, fail-safe module guarantees that the test current will be less than 10 mA even under worst case conditions of simultaneous failure of multiple circuit elements.
2. Ease of operation – Direct reading. 4-wire test leads arrangement, which automatically compensate for lead resistance.
3. Power charger interlock. Connection of the charger is through the same connector as the test lead cable connector. This prevents from using the tester while it is connected to external power.
4. Connection to a computer via fiber optic cable to ensure safe meter integration and physical separation between the computer’s power system and the squib. On the computer side it can be configured for USB or Ethernet connection. This allows complete and safe operation of the tester from a computer. The customer can create their own custom testing program to interface with the tester, or they can use software provided by Space Electronics. Software control allows:
   • Remote Data Reading: Automated data collection ensures that correct values are recorded, without risk of operator error.
   • Data Logging: Store measured values in a database.
   • Scripting: Test Engineers can create manual or automated test sequences.
   • Reporting: A full UUT report can be generated, printed, exported to Excel and stored to disk.
   • Analysis: Statistical analysis of a dataset can be performed on stored measurements.
5. Detect missing or broken wires in the 4 wire test leads to the UUT. Diagnose and locate wiring errors that other testers would show as a resistance or open circuit reading.
6. Digital Calibration. Our model 101-SQB-PTU is calibrated digitally, with no requirement to open the meter or trim internal or external potentiometers. The calibration kit consists of software, UUT cable, and all necessary interfaces to connect the meter to a regular Windows-based desktop or laptop computer.

All other meters are calibrated manually with built-in certified resistors and an externally accessible potentiometer (no need to ever open the tester).

Other benefits of the 101-SQB-PTU include:

• Quick Reading. Squib tester stabilizes readings in less than 2 seconds. Reading is truly stable and clearly legible for operator (no interpretation between fluctuating values).
• Measurement Reading Ease. Our squib testers have a large format LCD display, with clear indication of range being measured, status of battery, status of calibration, and large format reading values including units. Reduces operator error through misreading.
• Immune to differences in lead resistances. Our squib testers are specifically designed to withstand unequal lead resistances on the 4 wire cable lines.
• RF Immunity. Our squib testers are hardened against external electromagnetic and RF signals.
