Capacitance Measurement; Diode And Continuity Test; Temperature Measurement; Frequency Measurement - USAG 075 D Manual De Instruccion

• Connect the leads to the resistor under measured.
Note: If resistance is over the selected range value, "1" will display thus, should set
the range knob to a higher range, when resistance is over 1MΩ, it should take a
few minutes to be stable, it's normal at high resistance measurement. When input
terminal is open, overload displays.
When measuring resistance on line, be sure power is turned off and
all capacitors are released. Never input voltage at this range.

Capacitance measurement

• Set the knob to a proper range.
• Apply the black test lead to "COM".
• Apply the red test lead to "F – mA – TEMP".
• Apply the capacitor under measured to the input terminal by test leads (the
polarity of the red lead is "+") the capacitance will display on LCD.
Note: If the capacitance under measured is larger than the max. value of selected
range, LCD display "1" and should set the knob to a higher range.
It's normal that LCD does not display zero before measuring. The remained reading
has not effect on the measuring value. To get the real reading, minus the remained
reading from tha displaying reading.
Release all capacitors completely before measuring. The capacitors
under measured should not be connected to other components.

Diode and continuity test

• Set the knob to "
• Apply the black test lead to "COM" terminal.
• Apply the red test lead to "V – Ω – Hz" terminal. (The polarity of the red lead
is "+"). Connect the test leads to the diode under measured, and the red leads
connects to positive polarity, the reading is approx. forward voltage drop value.
Connect the test leads to the circuit under measured, if buzzer sounds, the
resistance between the two points is less than approx. 70 ± 20Ω.
Do not measure voltage at current.

Temperature measurement

• Set the knob to °C or °F range.
• Apply the negative polarity of cold junction of thermocouple (black plug) to
"COM" terminal.
• Positive polarity (red plug) to "mA" terminal.
• Put the probe on or in the object under measured, the value displays in °C or °F
on LCD.

Frequency measurement

• Set the knob to "200 kHz".
• Apply the test leads or shield cable to "COM" and "V – Ω - Hz" terminal.
• Apply the test leads or shield cable crossly to signal source or load under
measured.
