Page 3: Safety Information & Precautions
SAFETY INFORMATION Hi-Test Detection Instruments is now a part of HD Electric Company. HD Electric Company, located in Waukegan, Illinois, USA is a manufacturer and provider of a wide range of electrical equipment. At HD Electric Company, we understand the special training and requirements for work on electrical power distribution systems. - Page 4 SAFETY PRECAUTIONS 1) DO NOT use this tester on any part connected to an energized circuit. FLASH OVER WILL OCCUR. 2) DO NOT attempt to use the tester while it is connected to the battery recharging cable. This can result in destruction of the transformer on the recharging power cable. 3) DO NOT touch the bare end of the high voltage test lead when the tester is on, or for 15 seconds after it shuts off.

Page 5: General Operating Instructions
GENERAL OPERATING INSTRUCTIONS Charging the Battery: 1) Fasten the wall rack to a wall near a 110/120 VAC outlet which has a non-interrupted power supply. Damage will result to the charger if it is subjected to power surges from an outlet which is being turned off and on at a main switch. 2) Remove test leads from the tester prior to recharging. -
Page 6: Internal Fuse
Internal Fuse: 1) The tester is internally fused and the fuse is changed as follows: a) Ensure the Voltage Adj. knob is set to MIN. (fully counterclockwise). Remove the test leads from the tester and turn the tester over; b) Remove the 4 screws from the bottom panel and remove the battery cover door; c) There are 2 fuses located in the battery compartment. -

5) Gradually increase the voltage imposed on the arrester by turning the Voltage Adj. knob clockwise until the voltage imposed on the arrester is at the MCOV rating of the arrester. 6) Read the current leakage displayed on the current meter (short display) of the tester. INTERPRETATION: A) If the current leakage through the arrester at MCOV voltage is minor (0 to 10 microamps) the arrester is functioning correctly with regard to leakage current at MCOV. -

6) Repeat Steps 3 through 5 with three or four additional arresters that are the same manufacturer and same rated capacity as the first one. This is necessary to determine the“performance profile”of this particular arrester under test with the HiSat-25 Surge Arrester Tester. NOTE: Differences in the performance of silicon carbide arresters when being tested are a function of differences in the gap structure among these arresters. - Page 9 b) COMPOSITE/POLYMER/NON CERAMIC INSULATORS - failure of these type typically begins on the external surface and visible signs of potential trouble include extensive evidence of surface tracking and/or changes in the color/consistency of the skirt material. They can be tested using the procedure set out on the following page, however, the visible signs described above rarely coincide with dielectric failure.

Procedures for Testing Surface Conductivity: 1) Ground the tester using the Static Ground Strap provided (See Safety Precaution #7). 2) Connect the High Voltage and Ground leads to the tester. 3) Push the On button and set the Voltage Adj. at 10 - 15 kVDC. 4) Place both tester leads on the external surface of the insulator (whether porcelain, glass or non ceramic) three or four inches apart. -
Page 11: Testing Fuses For Continuity
TESTING FUSES FOR CONTINUITY Separation of a fuse causes service problems. Using the following procedures, the continuity of a fuse can be quickly checked. IF YOU ARE TROUBLESHOOTING IN THE FIELD, follow all company procedures and safety precautions and DISCONNECT THE FUSE FROM THE CIRCUIT before using the tester. 1) Ground the tester using the Static Ground strap provided (See Safety Precaution #7). -
