The ranges available are Auto, 1 nF, 10 nF, 100 nF, 1 μF, 10 μF, 100 μF, 1 mF,
10 mF, and 100 mF when using the Capacitance Normal I mode. The LoI mode
is limited to Auto, 1 mF, 10 mF, and 100 mF ranges.
Capacitance Menu
This section explains the Capacitance menu.
 (Range): Each of the Capacitance ranges can be manually selected or
select Auto to put Capacitance into autorange. Make the range selection with the
softkeys or use the navigational keys to highlight the selection and push .
Push  to return to the start page of the menu.
 (Resolution): Capacitance has resolution 4 digits or 5 digits. Select the
resolution with the softkeys or use the navigational keys to highlight the selection
and push . Push to return to the start page of the menu.
 (LoI): Two different current levels are available to make capacitance
measurements. LoI OFF is the default, and makes measurements in all of the
ranges (1 nF to 100 mF). LoI uses a lower stimulus current and is limited to three
ranges (1 mF to 100 mF). LoI ON may be useful if the default current causes a
calibrator's capacitance function to overload in these ranges. See Specifications.
Measure Capacitance
The Product uses a dc charge/discharge method to measure capacitance, based
on the formula C = I dV/dt. One use for the Capacitance function is to measure
the output of multi-function calibrators, for example the Fluke 5522A. Connect the
Product INPUT HI to the calibrator OUTPUT HI and the Product INPUT LO to the
calibrator OUTPUT LO. With polarized capacitors, connect the positive side to
LO and the negative side to HI (VΩ|) as shown above in Figure 14. Capacitance
is a 2-wire measurement and the Product reading includes the capacitance of the
connecting leads. Compensate for the connecting leads by using the Zero
function. To do so, connect one end of the connecting leads to the Product, and
the other end to an open circuit on a non-conducting work surface. Push 
and select  (Zero Range) or  (Zero Function) as appropriate. The
Zero function can accommodate approximately 200 pF of lead capacitance so
Fluke Calibration recommends the use of short, low capacitance connecting
leads. The standard lead set capacitance is less than 200 pF so this will be
adequate.
The standard lead set can be used for most capacitance measurements.
