Rack-Mounted Single Channel Igniter Circuit Testers

Single Channel Fail Safe Squib Tester Variants

• The tabletop or rack-mounted 101-SQB-BTP is a single channel unit with safe connection to external power. It comes in two different packagings, either as a benchtop unit or a standard 19″ rack. Either version can be used either as a stand-alone tester or as the sensing element of a multi-channel tester.
• The squib testing module 101-SQB-RAK is the sensing element that must be integrated in a rack with an isolated power system (not provided). It is meant to be implemented as the core of a multi-channel tester.
• We also make a battery-powered version, either in a portable packaging (101-SQB-PTU) that can be used in the field or a benchtop packaging (101-SQB-PTU-B).

Squib Tester Benefits

• 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.
• 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.
• 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.
• Ease of operation – Direct reading. 4-wire test leads arrangement, which automatically compensate for lead resistance.
• Digitally calibrated. Calibration of the squib tester is performed 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.
• Optional calibration standards are available. This provides a set of NIST traceable resistors that have been calibrated to the ANSI/NCSL Z540-1 standard.
• Remote Readout and Remote Control is available for all testers. Optional software allows complete operation of the tester from a computer system. Test Engineers can program manual or automated test sequences through scripting software.
• Record Measurement Data. Data logging is available. Measurements are stored in a database. A full report of a UUT can be printed or exported to Excel. Statistical analysis of UUT’s can be performed.
• Switching Matrix. A front end to interface with multiple circuit paths is available. Customization of the front end will ensure your exact requirements are met. Please see our multi-channel circuit testers for more information.
• Fiberoptic Interface is standard on all squib tester units. It is used for calibration, remote operation, data logging, and integration into a rack-mount multi-channel tester. Connection is fiberoptic to ensure safe meter integration and physical separation between the computer’s power system and the squib.
• Isolated Power Supply. The power supply of our squib tester is 100% floating for safety isolation between power source and the squib. This eliminates current leakage between the UUT and earth ground, and between the meter and earth ground. As a consequence the UUT can be earth-grounded without corrupting measurement accuracy.
• Immune to differences in lead resistances. Our squib testers are specifically designed to withstand unequal lead resistances on the 4 wire cable lines.
