Page 18Testing the Resistance Function (for 61-340 / 61-342)To verify the accuracy of the resistance function, do the following:1. Connect the calibrator to and COM on the meter.2. Turn the rotary switch to .a. Press the SELECT button to select the Ω function3. Apply the inputs for step 1-7 in Table 5.4. Compare the meter display readings to the display readings in Table 5.5. If the display reading falls outside of the range shown in Table 5, the meter does not meetspecification.Table 5 Ω Resistance Test:Step Range Source Reading1 400Ω* 4.0Ω 3.5 to 4.52 400Ω* 300.0Ω 295.9 to 304.13 4kΩ 3.000KΩ 2.968 to 3.0324 40kΩ 30.00KΩ 29.68 to 30.325 400kΩ 300.0KΩ 296.8 to 303.26 4MΩ 3.000MΩ 2.968 to 3.0327 40MΩ 30.00MΩ 29.35 to 30.65*Lead resistance on the 400Ω range is not included in error.Testing the Capacitance Function (for 61-340 / 61-342)The meter measures capacitance by charging the capacitor with a known direct current, measuring theresultant voltage, and calculating the capacitance. If the same capacitance is measured on animpedance bridge, a different reading may result. This variance is likely to be greater at higherfrequencies.To verify the accuracy of the capacitance measuring function, do the Following:1. Apply the capacitor to the and COM inputs on the meter. For steps 1 through 7 in Table 6.2. Turn the rotary switch to .a. Press the SELECT button to select the functionb. Press the REL button to make the display is zero3. Compare the reading on the meter display to the reading in Table 6.4. Note : The meter selects the proper range automatically. Each measurement takes about onesecond per range, readings >40.00μF will take ≥ 5 to 30 secondsForm Number 25. If the display reading falls outside of the range shown in Table 6, the meter does not meetspecification.TM61340-2 Rev November 2007
