10.3 DC CURRENT MEASUREMENT
Do not measure circuits that may contain voltages > 600 VDC or
> 600 VAC
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms. Always place your fingers behind the protective
edges of the test probes while measuring!
1.
Set the rotary switch in the desired "
2.
Connect the red test lead to the "V
measurements up to 200 mA or to the "10A" jack for measurements
from 200 mA to 10 A. Connect the black test lead to the "COM" jack.
3.
Open the circuit in which the current is to be measured and connect
the test leads to the circuit IN SERIES.
4.
Read the current value and the polarity of the red lead connection on
the LCD display.
Notes
•
If the range is not known beforehand, set the selector switch to a high
range and lower gradually.
•
An over-range is indicated by OL or -OL. Set to a higher range.
•
The maximum input current is 500 mA or 10 A depending on the jack
which is used. The F0.5 A fuse protects the current measuring circuits
that measure up to 200 mA. The F10 A fuse protects the current
measuring circuits that measure from 200 mA up to 10 A. the maximum
time of the 10 A range measurement each is 15 seconds.
10.4 AC CURRENT MEASUREMENT
Do not measure circuits that may contain voltages > 600 VDC or
> 600 VAC
Use extreme caution when measuring voltages higher than 60 VDC
