  • How to select the primary measured parameter when operating AKTAKOM AMM-3320 RLC Meter?

    In order to select the primary parameter when operating AKTAKOM AMM-3320 RLC Meter you need to press “FUNC” button. Each time you press "FUNC" the parameter changes in the following order: AUTO LCR (automatic selection of the value under measurement) ► L-Q (measurement of inductance and quality factor) ►C-D (measurement of capacity and dissipation factor) ►R (resistance measurement) ►DCR (DC resistance measurement).

    L/C/R values can be positive and negative. If in C-D mode the primary parameter has "-" sign then the element should be measured in inductance mode. If in L-Q mode the primary parameter has "-" sign then the element should be measured in capacity mode. If in R mode the primary parameter is negative then this means calibration error and it is necessary to re-calibrate AMM-3320 RLC meter.

    How to select the secondary measured parameter when operating AKTAKOM AMM-3320 RLC Meter?

    In order to select the secondary parameter when operating AKTAKOM AMM-3320 RLC Meter you need to press “D/Q/ESR” button. Each time you press the button the parameter changes in the following order: D (dissipation factor) ► Q (quality factor) ► θ (phase angle) ► ESR (equivalent series resistance)

    What is the purpose of AutoLCR mode in AKTAKOM AMM-3320 RLC Meter?

    AutoLCR mode is used in AKTAKOM AMM-3320 RLC meter for automatic selection of the primary and secondary parameters for L, C, R modes and it is activated on default. Selection is made in accordance with the test result. This function makes it convenient to take measurements of different-type or unknown elements.

    Condition Primary parameter Secondary parameter
    lθl<-11° Capacity (C) Dissipation factor (D) (if C<5pF the secondary parameter is Rp)
    lθl>11° Inductance (L) Quality factor (Q)
    lθl<11° Resistance (R) Phase angle (θ)

    Does Aktakom AM-3055 Multimeter for SMD (Surface Mount Device) have auto power off mode?
    Yes, it does. Auto power off mode that Aktakom AM-3055 Multimeter for SMD has helps to prolong the battery life. If no button was pressed within 10 minutes you will hear a beep signal and the device will automatically go off. In this case all of the current device settings will be saved by the time of switching off.

    How can I set auto measurement mode on Aktakom AM-3055 Multimeter for SMD (Surface Mount Device)?
    Press and hold FUNC button for over 1 sec.: Aktakom AM-3055 multimeter for SMD will turn on and enter measurement auto setting mode. Now you may start the operation: measure resistance or capacity, take continuity or diode testing.

    What is the purpose of Handler/Sorter interface use on DB25 of AKTAKOM AM-3001 LCR meter?
    Handler/Sorter interface on DB25 indicates sorting data as well as the information about the measuring process. The device switching with this interface is made by TTL signal setting. Trigger output protection is provided within ± 15 V.

    Please explain more about "rdg" in the inductance specification table

    The accuracy of a digital tester is defined as the difference between the reading and the true value for a quantity measured in reference conditions. Accuracy is specified in the format: (±xx% rdg ±xx dgt).

    The first portion identifies a percentage error relative to the reading, which means it is proportional to the input. The second portion is an error, in digits, that is constant regardless of the input. "Rdg"is for reading and "dgt"is for digits. Dgt indicates the counts on the last significant digit of the digital display and is typically used to represent an error factor of a digital tester.

    AutoPowerOff disabling

    To save the battery charge the device is provided with activated Auto power off function (APO).

    In approximately 15 min. of inactivity there comes a warning signal, in one more minute the present function switches the device off. Pressing any key or turning the measuring function selecting knob leads to the device on-status.

    To disable APO mode press and hold REL key, APO indicator will disappear from the screen. To enable APO mode again press and hold REL key.

    Note: APO function is automatically switched off changing in MIN/MAX mode.
