    At long last - the General Class videos are finally here. This is a 3-part session that took some time to edit. I wasn't happy with the session I recorded in Spring of 2016, so I had to wait until September for the W5HRC club's next class. Then editing, traveling and all of the other videos pushed it back some - but it is finally here and good until 2019. So you have about 2.5 years to go get your upgrade. Let me know in the comments below once you pass your exam!

CAUTION: SHOCK HAZARD!!! This unit does not put out enough current to kill you (unless you have a bad heart), but the shock WILL HURT (Minimum 10V will put out 50 milliwatts, Maximum 1090V will put out 5.45 Watts). NOTE 1: Every time you relocate the Megger to another work location or whenever you change the Voltage setting, verify that the needle returns to Infinity and re-do the Calibration Procedure (aka Set Infinities) as necessary. NOTE 2: If either Set Infinity or Set Infinity Highest Range cannot be attained, even after resetting the needle with the mechanical adjustment, reject the Megger. Internal calibration is required and your readings will not be accurate. ---------- 1863 and 1864 Megohmmeters Instruction Manual Operation - Section 3 3.1 MEASUREMENT SETUP. 3.1.1 Ground-Link Connection. The grounding link connected to the uninsulated, grounded, binding post can be connected from this ground terminal to the GUARD or the + UNKNOWN terminal. The ground link should be connected to the GUARD terminal if the sample to be measured is a small, separate component, or if it is a component mounted in an enclosure that should be guarded. However, if one terminal of the unknown must be grounded, then the link should tie the + UNKNOWN terminal to the instrument case. 3.1.2 Test Voltage Selection. The TEST VOLTAGE switch(es) should be set to the desired measurement voltage. The 1863 Megohmmeter has five individual test voltages, 50, 100, 200, 250, and 500 V. The 1864 Megohmmeter has a selection of 10 to 109 V in 1-V steps or 100 to 1090 V in 10-V steps. On the 1864 the right-hand TEST VOLTAGE switch must be set to the V position for the first set of voltages and to the 0V position for the latter set of voltages. 3.1.3 Set INFINITY Adjustments. To adjust the SET INFINITY controls, proceed as follows: a. Turn the instrument on. b. Set the function switch to DISCHARGE. c. Set the multiplier dial to any range. d. Make certain that there isn't anything connected to the UNKNOWN terminals. e. Adjust the SET INFINITY control for an INFINITY reading on the meter. The adjustment on the 1863 is made with a screwdriver; on the 1864 with the knob provided. f. Set the multiplier switch to the highest range (Type 1863, 1T-100G; Type 1864, 10-1T). g. Set the function switch to MEASURE. h. Adjust the SET INFINITY HIGHEST RANGE on the 1863 (screwdriver adjustment) or 1864 (knob adjustment) for an INFINITY meter reading. If these adjustments cannot be set to give an on-scale reading, turn the instrument off and adjust the mechanical meter adjustment (the center screw on the meter) to give a meter reading of less than a line width beyond INFINITY. Repeat steps a through g. 3.1.4 Connection of Unknown. Small components should be connected directly to the UNKNOWN terminals. Insulated leads (GR 274-LSR Single-Plug Patch Cord) can be connected to a nearby unknown, however, if the unknown resistance is high, leakage between the leads will cause a measurement error and changing capacitance to the high lead will cause a transient meter deflection. For such high resistance measurements, a shielded system is preferable. 3.2 MEASUREMENT PROCEDURE. 3.2.1 General. Either of two measurement procedures is used, depending on whether or not the correct resistance-multiplier range is known. If the range is not known, the search procedure (paragraph 3.2.2) should be followed. If repetitive measurements are to be made on a given range (i.e., if similar components are to be sorted) the sort procedure (paragraph 3.2.3) should be used. 3.2.2 Search Procedure. When the approximate resistance of the sample to be measured is not nown, proceed as follows: a. Set the multiplier switch to the lowest range. b. Set the function switch to DISCHARGE. c. Connect the unkown between the UNKNOWN + AND - terminals. d. Set the function switch to MEASURE. e. Rotate the multiplier switch cw until the meter gives a reading of less than 5. f. The resistance of the unknown is the meter reading multiplied by the multiplier-switch indication. 3.2.3 Sort Procedure. When the approximate resistance fo the unknown is known, proceed as follows: a. Set the function switch to DISCHARGE. b. Set the multiplier switch to the desired range. c. Connect the unknown between the UNKNOWN + and - terminals. d. Set the function switch to MEASURE. e. The resistance of the unknown is the meter reading multiplied by the multiplier-switch indication. For go-no-go checks, it is often useful to make a limit line of the outside of the meter case with a strip of masking tape.
