This instrument was calibrated using standards that are traceable to the National Institute of Standards and Technology (NIST).
Page 10
Elimination of any connections in the earth grounding system or bypassing any safety systems will void this warranty. This warranty does not cover accessories not of Associated Research, Inc. manufacture. Parts used must be parts that are recommended by Associated Research, Inc. as an acceptable specified part. Use of non-authorized parts in the repair of this instrument will void the warranty.
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.
Direct Current, DC: Current that flows in one direction only. The source of direct current is said to be polarized and has one terminal that is always at a higher potential than the other. Frequency: The number of cycles an AC waveform repeats over time. Usually given in Hertz (Hz). Ground: Refers to the point of low potential in a circuit to which all other voltages are referenced.
FAX: 1 (847) 367-4080 LAKE FOREST, IL 60045-4546 U.S.A. info@asresearch.com E-MAIL: Service Interval Associated Research, Inc. will not be held liable for injuries suffered if the instrument is not properly maintained and safety checked annually. See section 1.1. Warranty Policies for more information.
1.4.2. Test Station Location Select an area away from the mainstream of activity where employees do not walk while 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 test operators should be allowed inside.
Test operators should be familiar with methods to properly discharge a device under test in case test leads become disconnected during testing. If the instrument is used in a manner not specified by Associated Research, Inc. the protection provided by the instrument may be impaired.
1.5. Key Features of the HYPOT III SmartGFI™ disables the instrument’ s output voltage in less than 1 millisecond if excessive leakage to ground is detected. If enabled, PATENTED SMARTGFI™ SmartGFI™ automatically detects if the DUT is floating or grounding and turns ON or OFF accordingly.

5. OPERATING INSTRUCTIONS 5.1. Instrument Connections The test leads and the adaptor box may be connected to the jacks located on the front or back of Hypot III. These receptacles are wired in parallel and either set can be used depending on the specific application. 5.1.1.
5.1.3. Interlock Connector Hypot III is equipped with a Remote Interlock feature. Remote Interlock utilizes a set of closed contacts to enable the instrument’ s output. If the Remote Interlock contacts are open the output of the instrument will be disabled. To disable the Remote Interlock feature connect the Interlock Key into the Signal Input port located on the back of the tester.
Pressing the “ +” soft key will increase the output voltage and pressing the “ -” soft key will decrease the output voltage. Manual voltage adjustment temporarily overrides the voltage setting and only remains in effect until the test is terminated by Pass, Fail, or Abort conditions.
NOTE: For multi-step tests, use the “ ∧” and “ ∨” soft keys to scroll through the results. 5.5. Error Messages While performing tests a number of messages will be displayed to indicate the test state or test results. These messages are displayed in the status area of the screen located on the first line at the top of the LCD.
Page 51
Arc-Fail: This message appears on the display if the DUT arcing current exceeds the Arc Sense limit and Arc function is active (Arc Sense = 1… 9) during the AC/DC Withstand test. Short: This message appears on the display if the instrument detects a short circuit condition Breakdown: This message appears on the display if the DUT current is well beyond the metering range of the test and the arcing condition is beyond the arc sense limit.
6. CONNECTION OF REMOTE I/O Two 9 pin D-type connectors mounted on the rear panel provide REMOTE- INPUT-OUTPUT control and information. These connectors mate with a standard 9 pin D-type subminiature connector provided by the user. The output mates to a male (plug) connector while the input mates to a female (receptacle) connector.
125 VAC (0.5 ADC / 30 VDC). The signal outputs are provided on the 9 pin female D-type connector. Below is a list that indicates what conditions activate each pin. When a terminal becomes active the relay closes thereby allowing the external voltage to operate an external device.

remains active even when a remote reset switch is connected so that high voltage can be shut down from either location. The Remote File Select function gives the user the capability to quickly change parameters and initiate a test remotely. Three internal memory programs can be accessed by connecting terminals 7, 8, and 9 in different combinations.
