4.7 CAPACITANCE MEASUREMENT
4.7.1 Insert the black lest lead in "COM" terminal and the red one in "VΩmA" terminal;
4.7.2 Turn the rotary to switch to "
4.7.3 If the LCD doesn't display "0", press "RANGE/REL" to clear the reading;
4.7.4 Connect the capacitor to "COM" and "VΩmA" terminal. (Note: the red test leads is
for posiDve pole +). LCD displays capacitance value.
NOTE:
1) Don't input voltage or current under capacitance ranges;
2) Press "RANGE/REL" to clear the reading before tesDng to assure the accuracy;
3) There is only the auto range mode under the capacitance range;
4) The capacitor must be completely discharged before tesDng to avoid damage the
meter,;
5) The reading of a higher than 600uF range will take more several seconds to be
stabled.
4.8 FREQUENCY MEASUREMENT
4.8.1 Insert the lest leads or shielded cable into "COM" terminal and "VΩmA" terminal;
4.8.2 Turn the rotary to switch to "Hz" range, connect the test leads or shielded cable to
the signal source or the load which is tested (It should over 3Hz).
4.8.3 Press "SELECT/
" key to choose frequency/duty cycle measurement, LCD will
display the frequency or duty cycle of the tested signal source.
NOTE:
1) There is only the auto range mode under the frequency range;
2) When the input is higher than 10V AC rms, please switch to
frequency or duty cycle to measure;
3) In noisy environment, it's be]er to use shield cable to measure a low signal;
4) Do not touch the high voltage circuit when measuring high voltage circuit;
5) Don't input voltage higher than 250V DC/AC peak value under Hz ranges, or it may
damage the meter.
4.9 NON-CONTACT VOLTAGE (NCV) DETECT
WARNING:
This funcDon could be affected by different external interference sources, and then the al
arm is acDvated by wrong signal. The measurement result is for reference only.
Turn the rotary funcDon switch to "NCV" posiDon. When the tesDng circuit is placed
above the meter, the meter displays the strength of signal, and the buzzer alarms with
"beep beep".
NOTE:
" range;
range and then select
1) Even if there is no voltage indicaDon, there may be voltage on the circuit. Do not rely
on NCV detector as the only way to detect voltage.
2) Voltage detecDng may be affected by power socket design, type of insulaDon and its
thickness and other factors.
3) Interference sources in the external environment, such as flashing light, motor,
would cause wrong signal to acDvate alarm funcDon.
4.10 DIODE AND CONTINUITY TEST
4.10.1 Insert the black test lead into "COM" terminal and the red one into "VΩmA"
terminal (the polarity of red lead is "+");
4.10.2 Turn the rotary switch to "Ω
"
" mode;
4.10.3 Forward measurement: connect red test lead to the posiDve polarity and the
black test lead to the negaDve polarity of the diode. LCD will display the approx. value of
forward voltage drop;
4. 10.4 Backward measurement: connect red test lead to the negaDve polarity and the
black test lead to posiDve polarity of the diode. LCD will display "OL";
4.10.5 The complete diode test includes forward and backward measurement, if the
result doesn't meet the descripDons above; it means the diode is broken;
4.10.6 Press "SELECT/
" key to select the conDnuity measurement mode;
4.10.7 Connect test leads to two points of tested circuit, if the resistance is less than 50
Ω, the built-in buzzer sounds.
NOTE:
1) DO NOT input voltage at "Ω
2) When test circuits, make sure the power is off and all capacitors are discharged. Any
negaDve potenDal or AC signal will acDvate the buzzer.
4.11 TEMPERATURE MEASUREMENT
4.11.1 Turn the rotary switch to "℃/℉" range. Press "SELECT/
mode.
4.11.2 Insert the cold end (free end) of thermocouple in "VΩmA(+)" and "COM(-)"
terminal, and put the working end (temperature measuring end) of thermocouple on the
surface or inside the tested object. Then LCD will display the temperature of tested
object, and the reading is in ℃/℉(when the polarity is contrary. The reading will
decrease when the temperature of the tested object increase).
NOTE:
1) When the input terminal is open circuit, it will display the environment temperature.
2) To ensure measure accuracy, do not replace the temperature probe unless it is
necessary.
3) Do not input voltage at temperature range.
