(like voltage measurement function) is selected. 4-10 Words AC Sensing Average: RD700 When measurement is taken by "average", no error is caused as the input signal is shine wave with no distortion. However, if the input waveform is distorted sine cave or non-sinusoidal wave, conversion to root-mean -square values is very difficult, resulting in a large error.
NMRR (Normal Mode Rejection Ratio) NMRR is the DMM's ability to reject unwanted AC noise effect, which can cause inaccurate DC measurements. NMRR is typically specified in terms of dB (decibel). This series has a NMRR specification of >60dB at 50 and 60Hz, which means a good ability to reject the effect of AC noise in DC measurements.
5-2 Voltage measurement / Frequency measurement WARNING 1. Never apply an input signal exceeding the maximum rating input value. 2. Be sure to disconnect the test pins from the circuit when changing the function. 3. Always keep your fingers behind the finger guards on the probe when making measurements.

5-4-4 Capacitance Measurement CAUTION 1. Discharge the capacitance before measurement. 2. Due to the measurement method that this device pours the current into a capacitor the measurement such as the big electrolysis capacitor of a leakage current is not suited in order that the error becomes big.
5-5 Temperature Measurement 1) Application The temperature of outside and water, object is measured. 2) Measuring ranges Centigrade: Range from -20 C to 300 C Fahrenheit: Range from -4 F to 572 F 3) Measurement procedure Input the -plug to COM input terminal and the +plug to TEMP terminal.
5-6 Current Measurement WARNING 1. Never apply voltage to the input terminals. 2. Be sure to make a series connection via load. × 3. Do not apply an input exceeding the maximum rated current to the input terminals. 4. Before starting measurement, turn OFF the power switch of the circuit to separate the measuring part and connect the test leads firmly.
For measurement of DCA, apply the black test pin to the negative potential side of the circuit to measure and the red test pin to the positive potential side in series with load. For measurement of ACA, apply the red and black test pins to the circuit to measure in series with load.
6-2 Calibration The manufacturer may conduct the calibration and inspection. For more information, please contact the manufacturer. 6-3 Battery and Fuse Replacement WARNING 1. If the rear case or the battery lid is removed with input applied to the input terminals, you may get electrical shock. Before starting the work, always make sure that no input is applied.
