Capacitance Measurement; Diode And Continuity Test; Temperature Measurement - Pro'sKit MT-1280 User Manual

2. When input terminal is in open circuit, overload displays.
3. When measuring in-line resistance, be sure that power is off and all capacitors are
released completely.

3.8 CAPACITANCE MEASUREMENT

1. Insert the red test lead to " V/Ω" terminal and the black one to " COM " jack.
2. Set the range knob to a proper capacitance range, connect the test leads to the
capacitor under measured (note: the polarity of red test lead is"+").
NOTE:
1. The measuring range for the capacitance of this meter is from 1.000nF to
2000F.
2. If LCD displays "0L." , it means over range.
3. Before measuring, LCD display might not be zero, the residual reading will be
decreased gradually and could be disregarded.
4. When measuring large capacitance, if creeps seriously or break capacitance, LCD
will display some instability value.
5. Discharge all capacitors completely before capacitance measurement to avoid
damage.
6. UNIT: 1uF =1000nF 1nF=1000pF

3.9 DIODE AND CONTINUITY TEST

1. Insert the black test lead to "COM" terminal and the red one to "V/Ω" jack ( Note:
the polarity of red test lead is"+").
2. Set the range knob to "
",connect the test leads to the diode under measured, reading is the approximation
of the diode positive volt drop.
3. Press the key "HOLD" to select the "
the measured circuit, if buzzer sounds, the resistance is lower than approx.
(50±20)Ω.

3.10 TEMPERATURE MEASUREMENT

Insert the cathode of thermocouple's cold end to " COM" jack and anode to " V/Ω"
terminal, put the working end on or in the tested object, temperature value can be
read on LCD in Celsius.
Press the key "
Notes: The maximum measuring temperature for the K-type thermocouple
dispatched at random is 250℃, and its instant measuring value can reach 300℃.
