4.2.10 DC Current

Range Resolution
200mA 0.1mA ±(1.5% of reading +1 graduation)
10A 10mA ±(2.0% of reading +5 graduation)
Overload protection: self-recovery fuse (F500mA/250V); No fuse
protection for the range of 10A.
Max. input current: mA: DC 200mA or AC (effective value);
10A: DC 10A or AC (effective value)
When measuring current which is greater than 5A, do not conduct
measurements consecutively for more than 4 minutes. After the
measurements are completed, do not conduct new current
measurements until 10 minutes later.

4.2.11 AC Current

Range Resolution
200mA 0.1mA ±(1.8% of reading +3 graduation)
10A 10mA ±(3.0% of reading +7 graduation)
Overload protection: self-recovery fuse (F500mA/250V); No fuse
protection for the range of 10A.
Max. input current: mA: DC 200mA or AC (effective value);
10A: DC 10A or AC (effective value)
When measuring current which is greater than 5A, do not conduct
measurements consecutively for more than 4 minutes. After the
measurements are completed, do not conduct new current
measurements until 10 minutes later.
Frequency response: 40Hz-400Hz, sine wave effective value
(mean value response)

5. Meter Maintenance

Basic maintenance information is given in this section, including
instructions for replacing a fuse and replacing a batter.
Do not try to repair the meter unless you are an experienced
service staff and you can get access to information regarding
related calibration, performance tests, and services.
