Static Recording This mode is used for recording maximum, minimum, and average capacitance values. It captures only stable values and updates to memory. Values that result in displaying “OL” or that are below 10 counts are not recorded. This mode is useful for determining the range of values a component falls into. Enable Static Recording Press the button to enter the static recording mode. The display should indicate “MAX AVG MIN” simultaneously.
Recording Mode Maximum Mode Mode Average Mode Minimum Recording Mode This is the default mode when first enabling static recording. In this mode, the “MAX AVG MIN” indicator will be displayed. At this point, the meter will start recording measured values applied to the input sockets or terminals. During the recording process, maximum, minimum, and average values will be stored. A beep will sound once a recording has been stored.
Minimum Mode In this mode, the “MIN” indicator will be displayed. This indicates that the value in the primary display represents the recorded minimum value. Average Mode In this mode, the “AVG” indicator will be displayed. This indicates that the value in the primary display represents the recorded average value. This average value is obtained by taking the maximum and minimum recorded values and taking the average of the two values.
Figure 19 - Steps to Use Static Recording 56
Relative Mode Relative mode is used when the user wants to “zero” the meter based on a reference value or wants to obtain a reading that is relative to a reference value. For example, if test leads are used in the measurement, the user may want to set a reference with the test leads inserted into the input terminals so that any measurements taken will not take into account the test leads. Setup Relative Mode To setup the relative mode, simply press the button once.
have test leads or wires connected to the meter in the fashion that they desire. Then, press the button once to “zero” out the meter as reference. This way, any measurements taken would not be affected by the test leads or setup.

measures capacitance by charging the capacitor with a known current, measuring the resulting time of the charging period, and then calculating the capacitance. The larger capacitors will take longer time to charge. Some large capacitors can take over a minute to measure due to the long charge time required. A flashing “C” indicates charging capacitor.
Measuring large capacitors: Measuring very large capacitors, for example a 100 mF value, requires a long time. . In this case, after inserting the capacitor into the meter’s terminals, the meter display may seem unresponsive and not respond to key presses. This is normal, and indicates that the meter is currently charging the capacitor. Depending on the size of the capacitor, this charging period can take up to 2 minutes until the meter becomes responsive and display the result.
The guard terminal is used to minimize noise and to help minimize parasitic components of the capacitor to be measured, thus allowing for more accurate results.
