Meter Procedure using Probe Adapter to measure Probe isolation(Sink) Current

The Dale 600/600E provides a method for testing probes independently from the system.The meter
utilizes a probe adapter to apply a test potential commonly to all connector pins.
The probe's imaging area is immersed in a saline solution along with a grounding probe from
the meter to complete the current path.Saline solution is a mixture of water and salt. The salt adds
a free ion to the water, making it conductive. Normal saline solution is 0.9% salt or 1/2 gram salt per
1 litre of water. If saline is not available, a mixture of 1 quart of water with one or more grams of
table salt, mixed thoroughly, will substitute.
Follow these steps to test each probe for leakage current.
1.) Turn the LOGIQ™ 100 PRO unit OFF.
2.) Plug the unit's mains powercord into the test meter, and the meter into the tested AC wall
3.) Connect the probe to be tested with the meter's appropriate adapter.
4.) Plug the saline probe into the test meter's "CHASSIS" connector.
5.) Plug the probe adapter into the test meter's connector marked "EXTERNAL".
6.) Set the meter's "FUNCTION" switch to EXTERNAL position.
7.) Put the saline probe and the probe's face(imaging area of the probe) into the saline bath.
To avoid probe damage and possible electric shock, do not immerse probes into any liquid
CAUTION
beyond the level indicated in the probe users manual.Do not touch the probe,conductive
liquid or any part of the unit under test while the LIFT GROUNDswitch is depressed.
8.) Have unit power ON for the first part; turn it OFF for the second half.
9.) Depress the ISO TEST (Dale 600) or Mains on Applied Parts(MAP) (DALE 601) ROCKER
10.) Follow the test conditions described in Table 10-18 for every probe.
11.) Keep a record of the results with other hand copies of Planned Maintenance data.
