11. Capacitance measurements
(Except MIT400/2, MIT410/2)
The MIT400/2 and MIT410/2 can measure circuit or component capacitance.
The test is automatic and starts the test immediately on connection of a circuit. If capacitance is large the circuit can take time
to charge. During this charge time the display will show "- - -". On completion of the test the display will show the measured
capacitance, and under range symbol "0.1 nf" or an over range symbol ">10uF".
11.1 Capacitance measurement procedure (2 terminals)
1. Connect test leads to the RED/BLACK test sockets on the instrument.
2. Select the uF measurement mode using the range knob.
3. Connect the test leads to the circuit to be measured. The instrument will check for a live circuit prior to making a
measurement.
4. The display will show the capacitance value of the circuit or component under test, as below:

11.2 Distance measurement by capacitance
For the MIT481/2 and MIT485/2 instrument, it is possible to measure cable length by capacitance in either feet or km, depending on
the SETUP status.
This is an automatic function and is calculated from the stored capacitance value based on the default value of 50 nF/km). This can be
adjusted in SETUP between 40 nF/km and 70 nF/km.
The result is displayed as below:
