True-rms MultimetersMaking Basic MeasurementsTo detect the presence of ac voltage, place the top of theMeter close to a conductor. The Meter gives an audible aswell as visual indication when voltage is detected. Thereare two sensitivity settings. The Lo setting can be usedon flush mounted wall sockets, power strips, flushmounted industrial outlets and various power cords. TheHi setting allows for ac voltage detection on other stylesof recessed power connectors or sockets where the actualac voltage is recessed within the connector itself. TheVoltAlert detector works in bare wire applications withvoltages as low as 24 V in the Hi setting.XW WARNINGIf there is no indication, voltage couldstill be present. Do not rely on theVoltAlert detector with shielded wire.Operation may be effected bydifferences in socket design,insulation thickness and type.Making Low Impedance CapacitanceMeasurementsFor making capacitance measurements on cables withghost voltage, hold qwhile turning on the Meter toswitch the Meter into LoZ, (low input impedance)Capacitance mode. In this mode, capacitancemeasurements will have a lower accuracy and lowerdynamic range.

115C and 117CUsers ManualUsing the BargraphThe bar graph is like the needle on an analog meter. It hasan overload indicator (>) to the right and a polarityindicator (+)to the left.Because the bar graph is much faster than the digitaldisplay, the bar graph is useful for making peak and nulladjustments.The bar graph is disabled when measuring capacitance. Infrequency, the bar graph and range annunciator indicatesthe underlying voltage or current up to 1 kHz.The number of segments indicates the measured value andis relative to the full-scale value of the selected range.In the 60 V range, for example (see below), the majordivisions on the scale represent 0, 15, 30, 45, and 60 V. Aninput of 30 V turns on the negative sign and the segmentsup to the middle of the scale.aej11f.eps16Testing the FuseTest fuse as shown below.<.5OKOKedy10f.eps
