Using Your Tester Safely ! Warning ! To avoid electric shock, use only the test leads supplied with the Tester. Use 600V rated probe tip adapters. (“600V” is printed on the equipment.) Remove all test leads that are not in use. Use only the 80i-500s ac current probe or a safety- designed equivalent (such as the Fluke Model 80i-1000s) that is rated for 600V on both the jaws and the measuring secondary. Remove any current probe that is not in use. In this manual, a WARNING identifies conditions

• When using the voltage test leads, keep your fingers away from the probe contacts. Keep your fingers behind the finger guards on the probes. • Use caution when measuring above 60V-dc or 30V-ac rms. Such voltages pose a shock hazard. AC Current Probe Safety Guidelines Follow these safety guidelines when using the AC Current Probe: • ! Never use the 80i-500s current probe on circuits rated higher than 600V. Use extreme caution when clamping the current probe around un- insulated conductors or bu

About This Manual This manual contains instructions for the 39 and 41B Power Harmonics Testers (hereafter referred to as the Tester). All information applies to both models unless otherwise indicated. Uses for the Tester You can use the Tester to measure voltage and current inputs at power line and harmonic frequencies. Using these inputs, the Tester automatically calculates power and a wide range of other measurements useful in determining harmonic distortion levels and sources. The Tester can

39/41B Users Manual Battery Considerations New alkaline C cells typically provide more than 48 hours of continuous operation. You can also use NiCad batteries. However, depending on battery condition, fully charged NiCad batteries provide 16 hours or less of continuous operation. Plan to replace the batteries as soon as possible after the b symbol comes on. Refer to User Maintenance later in this manual for battery changing instructions. Note After the Tester is dropped, it may not turn on. Chec

Input Connections Input Connections Refer to Figure 4 for a view of the two-input measurement scheme. To measure voltage, insert the red test lead in “V” and the black test lead in “COM.” Current measurement uses a BNC connector attached to “CURRENT PROBE.” Connect “V” and “COM” to measure only voltage; connect “CURRENT PROBE” to measure only current. Make all three connections for power measurements. Observe the following connection guidelines: • Current Clamp the Current Probe around the desir

39/41B Users Manual Using the Current Probe The accuracy of current and power readings depends on properly using the 80i-500s Current Probe. The accuracy specifications in this manual assume that the Current Probe is used correctly. • Always clamp the 80i-500s Current Probe with the arrow pointing toward the load (away from the source) for a phase measurement or toward the source for a neutral measurement. Press G to verify the Current Probe orientation. If the resulting VA Check Screen generall
