6-4 Capacitance Measurement
DANGER
● To avoid the danger of getting electrical shock, never make measurement of the circuit in which electric potential exists.
● Do not make measurement when opening the battery cover and the instrument case.
● Make sure to discharge the capacitor before making measurement.
(1) Insert the black test lead plug into the COM terminal and the red test lead plug into the VΩHz terminal.
(2) Set the Function Selector Switch to "
" position.(Then, "AUTO" and "nF" symbols are indicated on the display.)
(3) Press the REL key and "0" shall be indicated.(Then, "REL△" symbol is indicated on the display.)
(4) Connect the test leads to both ends of the resistance under test.
Measured value is indicated on the display.
Measuring unit "nF" / "uF" is automatically chosen and indicated due to the measured value.
Note) It may take some time according to the measuring capacitance.
Measuring capacitance < 4uF ---------- Measuring time is about 2seconds
Measuring capacitance < 40uF ---------- Measuring time is about 7seconds
Measuring capacitance < 100uF ---------- Measuring time is about 15seconds
6-5 Frequency Measurement
DANGER
● To avoid the danger of getting electrical shocks, never make measurement on a circuit over 300V AC/DC. (electrical potential to ground 300V AC/DC)
● Do not operate Function Selector Switch during measurement.
● Do not make measurement when opening the battery cover and the instrument case.
(1) Insert the black test lead plug into COM terminal and the red test lead plug into the VΩHz terminal.
(2) Set the Function Selector Switch to "Hz" position.(Then, "Hz" symbol is indicated on the display.)
(3) Connect the test leads to the circuit under test.
Measured value is indicated on the display.
Frequency can be measured at ACV, DCV, ACA and DCA functions by pressing "Hz/DUTY" Switch.
Concerning with the direction for use of "Hz/ DUTY" Switch, please reference to the item7-6 Hz/DUTY in this document.
Note) The minimum input can be measured is approx. 1.5V.
Readings of frequency may fluctuate or be influenced under noisy environment.
7. How to use Function Switches
7-1 SELECT Key
This key is to chose the measuring function at Ω/ Diode Check/ Continuity function and Current function(uA, mA, A). Actions at each function are as below.
● Ω/ Diode Check/ Continuity function
When setting the instrument to "Ω/ Diode Check/ Continuity" function, "Ω"measuring mode has been selected in the initial condition. By pressing "SELECT"
Key, measuring mode changes.
"Ω" → "Diode Check" → "Continuity Check"
