Page 7: Introduction
1. Introduction 1.1. Warranty Policies Associated Research, Inc., certifies that the instrument listed in this manual meets or exceeds published manufacturing specifications. This instrument was calibrated using standards that are traceable to the National Institute of Standards and Technology (NIST). -
Page 8: Safety Symbols
1.2. Safety Symbols 1.2.1. Product Marking Symbols Product will be marked with this symbol when it is necessary to refer to the operation and service manual in order to prevent injury or equipment damage. Product will be marked with this symbol when hazardous voltages may be present. Product will be marked with this symbol at connections that require earth grounding. -
Page 9: Glossary Of Terms
Hipot Tester: Common term for dielectric-withstand test equipment. Hypot®: Registered trademark of Associated Research, Inc., for its dielectric-withstand test equipment. Gas, liquid or solid material which has a volume resistivity of at least 10 12 ohm-cm and is used Insulation: for the purpose of resisting current flow between conductors. -
Page 10: Safety
The instrument, its power cord, test leads, and accessories must be returned at least once a year to an Associated Research authorized service center for calibration and inspection of safety related components. Associated Research will not be held liable for injuries suffered if the instrument is not properly maintained and safety checked annually. -
Page 11: Test Station
1.4.2. Test Station Location Select an area away from the main stream of activity which employees do not walk through in performing their normal duties. If this is not practical because of production line flow, then the area should be roped off and marked for HIGH VOLTAGE TESTING. No employees other than the test operators should be allowed inside. -
Page 12: Test Operator
1.4.3. Test Operator Qualifications This instrument generates voltages and currents that can cause harmful or fatal electric shock and must only be operated by a skilled worker trained in its use. The operator should understand the electrical fundamentals of voltage, current, and resistance. They should recognize that the test instrument is a variable high-voltage power supply with the return circuit directly connected to earth ground, therefore, current from the high-voltage output will flow through any available ground path. -
Page 13: Device Under Test
1.4.5. Device Under Test Never touch the Device Under Test (DUT) or anything connected to it while WARNING high voltage is being applied by the hipot. When testing with DC, always discharge the capacitance of the item under test and anything the high voltage may have contacted–such as test fixtures–before handling it or disconnecting the test leads. -
Page 14: Introduction To Product Safety Testing
1.5. Introduction to Product Safety Testing 1.5.1. The Importance of Safety Testing Product Safety Tests are specified during the design and development stages of a product as well as in the production of the products to insure that it meets basic safety requirements. These tests are designed to verify the safety of the electrical products in that they do not jeopardize the safety of the people, domestic animals, and property of anyone who may come in contact with these products. - Page 15 The equipment used for this test, a dielectric-withstand tester, is often called a “hipot” (for high potential tester). The “rule of thumb” for testing is to subject the product to twice its normal operating voltage, plus 1,000 volts. However, specific products may be tested at much higher voltages than 2X operating voltages + 1,000 volts.
- Page 16 AC testing advantages AC testing is generally much more accepted by safety agencies than DC testing. The main reason for this is that most items being hipot tested will operate on AC voltages. AC hipot testing offers the advantage of stressing the insulation alternately in both polarities, which more closely simulates stresses the product will see in real use.
-
Page 17: Insulation Resistance Test
which will indicate failure almost immediately if the total current reaches the leakage threshold during the initial charging of the product under test. Since a DC hipot does charge the item under test, it becomes necessary to discharge the item after the test. -
Page 18: Run Test
Compliance agency requirements vary on how different products are to be tested. Most specifications call for test currents of between 10 and 30 amps. Test voltages at these currents are typically required to be less than 12 volts. Maximum allowable resistance readings of the safety ground circuit are normally between 100 and 200 milliohms. - Page 19 current. Leakage current measurements are performed on products under normal conditions and single fault conditions as well as reversed polarity. This simulates possible problems, which could occur if the product under test is faulted or misused while the product is operating under high line conditions (110% of the highest input voltage rating of the product).

Page 20: Key Features And Benefits
1.7. Key Features and Benefits: HypotMAX The SmartGFI provides maximum operator protection. Patented SmartGFI® If the circuit detects excessive leakage to ground it shuts down the high voltage in less than 1 millisecond. SmartGFI is automatically activated if the DUT is not grounded. - Page 21 Tamper proof front panel This makes it possible to limit user access to the setup screens so that only authorized personnel with a controls security code can change test parameters. The electronic dwell control helps keep test results Electronic dwell settings consistent by ensuring that the test duration is the same for each product tested.

Questions and answers
i have the 7720 hypot, my item came back from cal on lock condition why cant i set my test parameters?
You can't set test parameters on the HypotMAX 7705 after calibration if it is in a lock condition because parameter adjustments are restricted to a special calibration mode. This mode is protected to prevent unauthorized changes, and access is likely limited or locked after calibration to maintain accuracy and compliance.
