Page 2 1) SAFETY Observe proper safety precautions when working with voltages above 30 Vrms, 42.4 Vpeak or 60 VDC. These voltage levels pose a potential shock hazard to the user. Do not expose this product to rain or moisture. The meter is intended only for indoor use. Keep your hands/fingers behind the hand/finger barriers (of the meter and the test probe assembly, where applicable) that indicate the limits of safe access of the hand-held parts during measurements.

Please refer to your respective model for function availability. 1) 4 digits 9999 counts dual displays 2) Push-buttons for special functions & features 3) Selector to turn the Power On or Off and Select a function 4) Input Jack for 10A (20A for 30sec) current function...
Page 5 Average sensing RMS calibrated RMS (Root-Mean-Square) is the term used to describe the effective or equivalent DC value of an AC signal. Most digital multimeters use average sensing RMS calibrated technique to measure RMS values of AC signals. This technique is to obtain the average value by rectifying and filtering the AC signal.
Page 6 4) OPERATION NOTE Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. AutoCheck mode (Models 525s, 521s, 829s only) This innovative AutoCheck feature automatically selects measurement function of DCV, ACV or Resistance () based on the input via the test leads.
Page 7 *As Hazardous-Alert: When making resistance measurements in AutoCheck mode, an unexpected display of voltage readings alerts you that the object under test is being energized. *Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. Our AutoCheck mode provides low (ramp-up) input impedance (approx.
Page 8 RANGE button momentarily to select another trigger level (voltage range) manually. If the Hz reading becomes unstable, select higher voltage range to avoid electrical noise. If the reading shows zero, select lower voltage range. Note: In dBm function, power up default reference impedance will be displayed for 1 second before displaying the dBm readings.

Page 11 Capacitance, Diode test functions Press the SELECT button momentarily to select the subject functions in sequence. Last selection will be saved as power up default for repeat measurement convenience. NOTE Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load.
Page 12 Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V. A reading higher than that indicates a leaky diode (defective). A zero reading indicates a shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections (reverse biased) across the diode.
Page 13 PC computer interface capabilities The instrument equips with an optical isolated interface port at the meter back for data communication. Optional purchase PC USB interface kit BU-82X is required to connect the meter to the PC computer. MAX/MIN/AVG* (REC) at fast 20/s measurement mode (Models 525s*, 521s*, 829s, 827s only) Press REC button momentarily to activate MAX/MIN/AVG* recording mode.
Page 14 Beep-Jack™ Input Warning The meter beeps as well as displays “InEr” to warn the user against possible damage to the meter due to improper connections to the A, mA, or A input jacks when other function (like voltage function) is selected. Beep-Jack Input Warning is disabled while Data Logging operation (Models 525s &...
