FUNCTION DESCRIPTION See Table 4 indicated for information about the terminals. 3.1 General Functions 3.1.1 DATA HOLD mode Data Hold mode makes the meter stop updating the display. Enabling Data Hold function in autorange mode makes the meter switch to Manual ranging mode, but the full-scale range remains the same.

  DIGITAL MULTIMETER DIGITAL MULTIMETER NOTE: 3.2 Measurement Functions If you manually change the measurement range after 3.2.1 AC and DC Voltage measurement entering the Data Hold modes, the Meter exits this mode. 2. To exit the manual ranging mode, press and hold down Warning RANGE key for two seconds.

  DIGITAL MULTIMETER DIGITAL MULTIMETER 3.2.2 Resistance measurement • The resistance function can produce enough voltage to forward-bias silicon diode or transistor junctions, Warning causing them to conduct. To avoid this, do not use the To avoid electrical shock and/or damage to the 40MΩ…

• Page 13: Diode Test

  DIGITAL MULTIMETER DIGITAL MULTIMETER 3.2.3 Diode Test Warning To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before testing diodes. Use the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, then measures the voltage drop across the junction, A good silicon junction drops between 0.5V and 0.8V.

• Page 14: Continuity Check

  DIGITAL MULTIMETER DIGITAL MULTIMETER 3.2.4 Continuity Check Warning To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before testing for Continuity. Continuity is a complete path for current flow. The beeper sounds if a circuit is complete. These brief contacts cause the Meter to emit a short beep.

• Page 15: Capacitance Measurement

  DIGITAL MULTIMETER DIGITAL MULTIMETER 3.2.5 Capacitance measurement Warning To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the dc voltage function to confirm that the capacitor is discharged. Capacitance is the ability of a component to store an electrical charge.The unit of capacitance is the farad (F).
