Normally yes they are in stock as can be seen in the product details. Occasionally there may be a period of unavailability which would be due to some part required in a new batch of the product being on a long lead time.

Yes. You can test a cable with any connector that fits the tester from one side ( either Local or Remote ) to the other. Plugging the cable into just one side will result in no connections being found.

Yes. The only problem is that most rechargeable batteries ( NiCAD or NiMH) have a much lower power rating then the equivalent Alkaline battery so it wont last as long as an Alkaline battery. Also the operating distance with "end to end" testing using a pair of AudioJoG testers may be less than expected. 

In most of our testers the memory used to store cable details is EEPROM which is a semi-permanent variety of the EPROM or ROM.
The only way to clear these details is to follow the instruction in the manual on how to clear the memory. Simply switch OFF and then On won't clear the memory.

No. Currently all our testers only do low voltage continuity testing on the cable.

Intermittent fault detection is available on the AudioJoG and AudioJoG Rack testers from 3 to 8.
As the test compares actual connections found against a stored set of connections it is necessary to first store the cable details using the method described in the manuals. Once stored, with the MEMORY LED lit, simply press and hold the test button until the the MEMORY LED starts to flash. Release the test button and you will see all the LEDs associated with the connector pins glow slightly dimmer than normal. The test keeps going until a fault is found so that the cable under test can be bent, shaken etc. Once the test stops due to a fault, pressing the test button or unplugging the cable the test will return to the previous state and to start it again you will need to repeat the step above.
