4.1 Outline
CS2676FX is the insulation resistance tester, it is the
type
of small insulation resistance tester,
simple features, easy to operate and easy to learn. Voltage switches manually, voltage settings for the
two ranges, divided into 500V and 1000V.The testing resistance value can be displayed at real time. In
additions, the lower limit can be set according to the users
’ actual needs. It is widely used to test the
insulation resistance value of the electronic components, household appliances, insulation materials,
instrumentation, lighting appliances, electric appliances quickly and accurately
.
4.2 Function introduction
4.2.1
Adjust the output voltage automatically
The tester is controlled by the negative feedback circuit, it can automatically adjust the voltage to the
setting value, so the output voltage will not be impacted by the load or the input power supply voltage.
4.2.2
Discharge
function
After the test is finished, the voltage will be needed some time to discharge fully after the power is
turned off. The tester is with the discharge function. After the test is finished, the tester is in the "stop"
state, which can discharge the DUT to protect the safety of the operator.
4.2.3
Set the lower limit of the measured object
The added up and low key can used to set the lower limit of the resistance according to the users
’ actual
requirements. For example: select 2M range, the test resistance range from
200kΩ to 2MΩ, the screen
shows the lower limit of 0.200, press the up key to increase one, long press the up key to increase ten; If
the lower limit is set too high, you can press the low key to reduce the lower limit, the minimum lower limit
is
200kΩ, the lower limit value shall not be 2 MΩ higher than the upper limit, if the lower limit is set to 2
MΩ, when press the start key, the tester will alarm. When users set the lower limit, the value will be
stored in the registers, the screen will display the lower limit when turn on the tester next time.
