PUSH START BUTTON The READY light of the Hipo Tester should go off since the safety Gnd return test from the device under test is taken over by the M25 Gnd tester using the relays Kl and K2 (see Dwg. #00431-01). The safety Gnd return is connected to the Gnd tester chassis and the chassis Gnd voltage output thru BP-1 is connected to the High Current Transformer. -
Page 19: Theory O F Operation
THEORY OF OPERATION SECTION Ill THEORY OF illGH CURRENT GROUND TESTING GROUNDING CONTINUITY 3- 1 Three production line tests are required by most regular agencies. These basic stept are grounding continuity, dielectric strength, and leakage current. The grounding of a product is one of the basic met hods of protection required by both international and domestic' safety agencies. - Page 20 Grounding continuity tests are also required to assure the s a fety and protection of manufacturing personnel during the performance of subsequent dielectric strength tests and leakage current tests. The grounding test achieves a two-fold purpose: (1) It assures the satisfactory completion of subsequent tests, and (2) assures that the second test can be accomplished without undue hazard to the test operator.

Page 21: Instrument Functional Diagram
INSTRUMENT FUNCTIONAL DIAGRAM Functionally, the GND tester is divided into three sections: The High Current generator and the General Control. A remote control option can be added to the total system (as shown in Fig. 3-2). The High Current generator consist of an AC transformer (50/60 Hz) specially designed to provide the current needed in the ground test. -
Page 22: Instrument Assembly Diagram
INSTRUMENT ASSEMBLY DIAGRAM The General Control can be commanded from the different front and rear panel controls shown on the left side of the diagram. It takes care of coordinating the different activities and sensing the status of the operation. It provides continuous monitoring through the front panel lights, buzzer and meters shown on the right side of the diagram. - Page 23 3-10 TOTAL CURRENT DETECTOR The A22 Board (Dwg. 446-01) receives the voltage across the current sense resistor set composed of 8 resistors of 2ohm 50W each giving a total resistance of 0.25 ohm. -----------, SENSE RESISTORS SOLID HIGH CURREN' HIGH CURRENT RELAY TRANSFORJ\1EF STATE...

- Page 25 The start signal also triggers the DELAY timer Ull for getting the RELAYS set up and at the end of the delay the START PULSE timer is triggered. This pulse gates the zero crossing pulses produced by-Q8 and trigger the TEST TIMER Ull. The output of the test timer drives the TEST LIGHT through U8 and drives the analo g switches in U 3 for enabling the monitoring of current and resistance.
