Model 550 Continuity Tester

Model 550

The DataSwitch Model 550 Continuity Tester is designed to test membrane switches rapidly and accurately foropens, shorts, and high resistance. This membrane switch tester is entirely self-pinning; no programming is needed. The Model 550 tests up to 50 trace lines.

STANDARD FEATURES OF MODEL 550 CONTINUITY TESTER

LED Testing: Lights switch-mounted LEDs to check for good or bad functions. Polarity can be determined by watching the LED panel.
High Resistance ('Hi-R') Test: Checks dielectric cross-overs by increasing sensitivity of the tester to 10 Megohms while testing for current leakage between conductors.
Test Head Connector Box: provides the 3 connectors necessary to interface with different types of tail terminations: solder tabs, receptacles, and connectorless tails. Connector styles may vary. The test head is connected to a header on the front of your membrane switch tester with a ribbon cable.

 


PURCHASE OF MODEL 550 CONTINUITY TESTER INCLUDES

For tails of up to 50 trace lines
One Membrane Switch Tester
Two 25-Pin Test Heads
Two-25 Pin Ribbon Cables
One 12-VDC Power Supply
One Year Warranty

 


PRODUCT ACCESSORIES FOR MODEL 550 CONTINUITY TESTER

Connector Adapter Board: Can be used in place of the test head to save wear on the right angle header, which is used for receptacles.
Test Clamp Fixture: Can be used for testing connectorless tails. It attaches to your membrane switch tester by using the 25 pin ribbon ribbon cable.

AVAILABLE OPTIONS FOR MODEL 550 CONTINUITY TESTER

Dual Range Switch: Adds a second test range to allow testing of switches with loop resistance of 0-30,000 Ohms.
Reverse Polarity Function: Tests LEDs wired in either a common cathode or a common anode configuration.
Volume and Tone Control: Helps differentiate between tones when more than one membrane switch tester is in use. Earphone Capability increases operator's listening comfort and awareness while silencing room noise. An earphone jack is installed on the back of the membrane switch tester.

DataSwitch Continuity Testers deliver the speed and ease of use required for a production-line environment, plus the versatility and accuracy needed for engineering research.

A test head connector box provides 3 connectors to interface with solder tabs, receptacles, and connectorless tails. Read More...

The DataSwitch Life Cycle Tester will test switch keys individually at a rate of one million strokes in approximately 48 hours. The switch is placed under an electrical load of 5 Milliamps DC, and is checked twice during each test cycle: once for resistance level during the 'down' stroke, and once for shorts during the 'up' stroke. Dual counters store the number of good cycles as well as the number of bad cycles (or misses). Read More...
The DataSwitch Contact Bounce Tester measures both make and break contact bounce times on any switch with reliability and accuracy beyond that of an oscilloscope. This tester measures and displays bounce times from 0.01 milliseconds to 99.9 milliseconds. Longer bounce times are indicated by an error light. Read More...
The DataSwitch LED Tester accurately tests embedded LEDs for function and correct polarity with minimal set-up time. It will handle membrane switches with tails of up to 25 trace lines. Read More...
