User’s Guide MultiMaster™ Digital MultiMeter Series With PC Interface Models: MM560A MM570A A
1) SAFETY This manual contains information and warnings that must be followed for operating the instrument safely and maintaining the instrument in a safe operating condition. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired. The meter is intended only for indoor use. The meter protection rating, against the users, is double insulation per IEC61010-1 2nd Ed., EN61010-1 2nd Ed., UL61010-1 2nd Ed. and CAN/CSA C22.2 No. 61010.
WARNING To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user. Do not touch test lead tips or the circuit being tested while power is applied to the circuit being measured. Keep your fingers behind the finger guards of the test leads during measurement.

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. The average value is then scaled upward (calibrated) to read the RMS value of a sine wave.
cause digit rolling or offset in voltage measurements. This series has a CMRR specifications of > 80dB at DC to 60Hz in ACV function; and > 120dB at DC, 50 and 60Hz in DCV function. If neither NMRR nor CMRR specification is specified, a DMM's performance will be uncertain. Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle.
DCV A ACV A Hz A Note: Line Level Frequency measuring function input sensitivity varies automatically with voltage (or current) function range selected. The lower the measuring range the higher the sensitivity. That is, mV function has the highest and the 1000V range has the lowest as in voltage function ranges.
Hz Logic Level Frequency and % Duty Cycle functions Press SELECT button momentarily to toggle between Hz and % (duty cycle) readings. The new setting will be saved automatically to the non-volatile memory as power up default. Press 500000 button momentarily to toggle between 5 full digits and 6 full digits Hz readings.
T1-T2 Dual Channels Temperature function (MM570A only) Press SELECT button momentarily to toggle between C and F readings, and the new setting will be saved automatically in the non-volatile memory as power up default. Press T1-T2 (RANGE) button momentarily to select T1, T2, or T1-T2 readings. Note: Insert the banana plug K-type temperature bead probe with correct channels T1-T2 readings require 2 probes. T2 A T1 - T2 A C F A 9 V1.1 8/12 polarities.
Resistance, Continuity functions Press SELECT button momentarily to toggle between and Continuity functions. The new setting will be saved automatically to the non-volatile memory as power up default. Continuity function is convenient for checking wiring connections and operation of switches. A continuous beep tone indicates a complete wire. A A CAUTION Using resistance or continuity function in a live circuit will produce false results and may damage the meter.
Capacitance, Diode test function Press SELECT button momentarily to toggle between Capacitance and Diode test functions. The new setting will be saved automatically to the non-volatile memory as power up default. CAUTION Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load. A A A Note: Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V.
other readings indicate the diode is resistive or shorted (defective). 12 V1.
A, mA, A, and %4-20mA Current functions Insert the red test lead into the correct A/mA or A input jack. Press SELECT button momentarily to select DC, AC, or DC+AC. The new settings will be saved automatically to the non-volatile memory as power up default. In DC mA function, neither in AC nor in DC+AC, press and hold the %4-20mA ( Hz) button for 1 second or more to display the current digital data in terms of loop current percentage (%) value. It is set at 4mA = 0% (zero) and 20mA = 100% (span) with 0.
PC-COMM computer interface capabilities The instrument equips with an optical isolated interface port at the meter back for data communication. The optional PC interface kit is required to connect the meter to the PC computer. The software features a digital display, an analog display, a comparator and a Data Graphical recorder display. Refer to the README file in the interface kit for further details. MAX/MIN RECORDING mode Press REC button momentarily to activate MAX/MIN recording mode.
Backlighted display Press the SELECT button for 1 second or more to turn on or off the display backlight function. It will also be turned off automatically after 30 seconds to extend battery life. Manual or Auto-ranging Press the RANGE button momentarily to select manual-ranging mode, and the meter will remain in the turns off. Press the button momentarily again to step range it was in, the LCD annunciator through the ranges. Press and hold the button for 1 second or more to resume auto-ranging mode.
5) MAINTENANCE WARNING To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input jacks and turn OFF the meter before opening the case. Do not operate with open case. Install only the same type of fuse or equivalent Calibration Periodic calibration at intervals of one year is recommended to maintain meter accuracy. Accuracy is specified for a period of one year after calibration.
