Warning
BE EXTREMELY CAREFUL WHEN USING THIS METER. Improper use of this
device can result in electric shock or destruction of the meter.
Take all normal safety precautions and follow the safeguards
suggested in this manual.
To exploit full functionality of the meter and ensure safe
operation, please read carefully and follow the directions in this
manual.
PRELIMINARY
Follow all safety and operating instructions to ensure safe use of
the meter:
- General protection against electric shock
- Protection of the meter against misuse
When the meter is delivered, check whether it has been damaged in
transit.
After being stored and delivered under harsh conditions, the meter
should be checked and confirmed whether any damages have been
incurred.
Test leads must be kept in good condition. Before using check
whether the insulation on test leads has been damaged and any wire
has been exposed.
Use the test leads supplied to ensure operation safety. If
required, they must be replaced with test leads of the same model
or class.
Technical specifications:
Environment temperature:235℃ Relative humidity:<75%
3.2.1 True RMS
3.2.1.1 For measuring non-sinusoidal waveforms, test error which is
occurred by using True RMS measurement techniques is less than by
using traditional average-reading techniques.
3.2.1.2 Both sinusoidal and non-sinusoidal waveforms can be tested
by True RMS Clamp Meter exactly. At AC A & AC V ranges, even short
two test probes there are still 1-50 digits might be displayed on
LCD. This is normal. Test result will not be affected.
3.2.1.3 At AC A and AC V range, True RMS value can be tested only
when input signal is more than 2% -100%of full range.
3.2.2 AC Current
| Range | Resolution | Accuracy |
| 2A | 0.001A | ±(4.0% + 20) |
| 20A | 0.01A | ±(2.5% + 8) |
| 100A | 0.1A |
- maximum/ input current:100A AC
- Frequency range:50Hz
3.2.3 DC CURRENT(2008D)
| Range | Resolution | Accuracy |
| 20A | 0.01A | ±(2.5% + 10) |
| 100A | 1A |
- maximum/ input current:100A DC
3.2.4 DC Voltage
| Range | Resolution | Accuracy |
| 2V | 0.001V | ±(0.8% + 5) |
| 20V | 0.01V |
| 200V | 0.1V |
| 500V | 0.1V | ±(1.0% + 5) |
- Input impedance:10MW
- Maximum/ input voltage:600V AC (Effective value)OR 600V DC
NOTICE:
At small voltage range, unsteady readings will appear before the
test leads contact the circuit. This is normal because the meter is
highly sensitive. When the test leads contact the circuit, the true
reading will be shown.
