Testing 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 function
3.Apply the inputs for step
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 meet specification.
Table 5 Ω Resistance Test:
Step | Range | Source | Reading |
1 | 400Ω* | 4.0Ω | 3.5 to 4.5 |
|
|
|
|
2 | 400Ω* | 300.0Ω | 295.9 to 304.1 |
|
|
|
|
3 | 4kΩ | 3.000KΩ | 2.968 to 3.032 |
|
|

Testing the Capacitance Function (for 61-340 / 61-342)
The meter measures capacitance by charging the capacitor with a known direct current, measuring the resultant voltage, and calculating the capacitance. If the same capacitance is measured on an impedance bridge, a different reading may result. This variance is likely to be greater at higher frequencies.
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 
function
b.Press the REL button to make the display is zero
3.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 one second per range, readings >40.00μF will take ≥ 5 to 30 seconds
5.If the display reading falls outside of the range shown in Table 6, the meter does not meet specification.
