[. . . ] Blue Switch - Push to switch to measure AC Voltage/Current or DC Voltage/Current in the Voltage/Current mode or to measure Resistance or continuity or diode in / / mode. Hold Switch - This switch is used to hold measured value for all functions, and then "HOLD" annunciator is displayed. Hz Switch - This switch is used to quickly view the frequency during measuring the AC voltage or current. Push " Hz" switch once the LCD is changed to display frequency. [. . . ] When disconnecting from a circuit, disconnect the hot lead first, then the common lead. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. 3 4 Overload Protection Function VAC & VDC AAC & ADC Ohms () Diode Continuity Overload Protection 1000V 1A/500V 10A/500V 600VAC/600VDC 600VAC/600VDC 600VAC/600VDC AC Volt Circuit Connection: APO RPM Hz Unit of Measure Multipliers For your reference, the following symbols are often used to make measurement easier: Symbol Verbal Multiplier M mega x 1, 000, 000 k kilo x 1, 000 m milli ÷ 1, 000 µ micro ÷ 1, 000, 000 Auto Power Off (APO) The APO sign on the LCD panel indicates the meter is working in the Auto Power Off mode. If the meter idles for more than 10 minutes, the meter automatically turns the power off. When this happens, the state of the meter is saved the meter can be turned back on by pushing any key switch or changing the rotary mode. The meter will give an alarm 15 seconds before the meter automatically turns the power off. To disable the auto power off function, power-up the meter while pressing either the range or Hz switch.

The meter displays total resistance through all possible paths between the probe-tips. [. . . ] Plug the black test lead into the COM port and the red test lead into the VHz port. The buzzer will sound if the resistance of the circuit measured is lower than 30. For AC Current Clamp (61-450): 1. Plug the black test lead into the COM port and the red test lead into the VHz port. Snap the jaw of the current clamp around one of the current carrying conductors. 15 16 General Specifications LCD Display: 3400 count maximum reading Bar Graph Display: 70 segment analog bar graph Polarity Indication: Automatic, negative indicated, positive implied Overrange Indication: "OL" or "-OL" Low Battery Indication: " " when the battery voltage drops below operating voltage Size (WxHxD): 88mm x 180mm x 33. 5mm (without holster) 94mm x 188mm x 40mm (with holster) Sampling: 2 times/sec LCD Display, 12 times/sec bar graph Auto Power Off: Approx.
