DC/AC μA	6000 μA	600.0 μA, 6000 μA
DC/AC mA	600.0 mA	60.00 mA, 600.0 mA

Example of DC 60-600 mA range measurement

Note:

As this instrument employs the mean value method for the AC detection, measurements become erroneous when the input waveform is other than a sine wave (the frequency range is 45 to 500 Hz).

● The current measured with this method decreases by the amount that the internal resistance of the current range is inserted in series. The effect of this phenomenon is particularly noticeable when measuring the current of a low-resistance circuit.

The resistance value of the A range is about 50 while that of the mA range is about 0.5 .

- If the displayed value hardly changes when the input signal is applied or becomes much lower than expected, the measurement terminals or function switch are set erroneously or the fuse ( 6.3 x 32 mm size, 0.4 A/1000 V) may be blown. Please check them.

● The A/mA switching is performed with the rotary switch.

● The DC/AC switching is performed with the SELECT button.

5-10-2 DC/AC current (DC/AC A)

WARNING

1. Never apply voltage to the input terminals.
2. The current measurement is accompanied with heat generation. When measuring current of 6 A or more, complete each measurement within 10 seconds and leave an interval of 5 minutes or more between measurements.
3. Perform measurement with the leads kept straight to prevent overheat.

Function	Maximum rated input	Ranges
DC/AC A	15 A	6.000 A, 15.00 A

Example of DC 6-15 A range measurement

Note:

- As this instrument employs the mean value method for the AC detection, measurements become erroneous when the input waveform is other than a sine wave (the frequency range is 45 to 500 Hz).

- If the displayed value hardly changes when the input signal is applied or becomes much lower than expected, the measurement terminals or function switch are set erroneously or the fuse ( 10 x 38 mm size, 16 A/1000 V) may be blown. Please check them.

● Continuous measurement is permissible for current below 6 A. (When measuring 6 A or higher current, complete each measurement within 10 seconds and leave an interval of 5 minutes or more between measurements.

- In case of measurements taking a long period, use the optional clamp probe.

● The DC/AC switching is performed with the SELECT button.
