1. Power off the instrument and connect the test leads
2. Plug in the power cord

9/25
Ensure that the power cord is well grounded, which is conducive to the stability of the test.
3. Turn the power at the rear of the instrument to the "on" state
At this time, the internal power of the instrument has been turned on, and the instrument is in
standby state.
4. Long press the panel power button to turn on the power
In the standby state, the panel power button light is red. Press the panel power button, the power is
turned on, the screen is lit, and the panel button light is green.
5. Set the test parameters (see section 2.2 for details)

Solutions
After the power switch at the rear of the
instrument is turned on, observe whether the
power button light on the instrument panel is
on.
When turning on the power, are all displayed in
the order of → model name → measurement
screen?
Please confirm whether the button light is on or
not, otherwise, send it for repair.
If the display is different, there may be a
malfunction in the instrument. Please send it in
for repair.
2.4 Test lead connection method
Warning!
• The test lead port is sharp, being careful not to get scratched.
• For safety, use the test leads supplied with the instrument.
• To avoid electric shock, make sure the test leads are connected properly
There are two ways of testing, one is two-terminal test, and the other is four-terminal test. The
four-terminal test is used to identify test errors caused by abnormal test connection lines or
abnormal test connection.

Chapter 3 Basic Settings
For testing safety, read this chapter before testing.
Note:
During the test, all keys except the [STOP] key are valid. The user must wait for the test to end, or
press the [STOP] key and send a test stop command to forcibly terminate the test. After the test
process is terminated, the instrument can be set.
3.1 Setting the test voltage
The user can choose between automatic range and manual range.
Note:
When the auto range is set to 30 mΩ or less, a maximum current of 1 A will flow into the
measurement target. Therefore, a maximum power of about 2 W may be applied. If you are
concerned about the following problems due to current measurement, select a smaller
measurement current range.
• The test object is blown (fuse, air pump)
• The measured object becomes hot and the resistance value changes
• The measured object is magnetized, and the inductance changes
If the power of the measured object is within the measurement range of each range, the power is
the resistance value × (measured current). When the measurement range is exceeded, the
maximum open circuit voltage × measured current may be reached.
After confirming the range, connect the object to be measured.
* When connected to the measured object, a maximum inrush current of 5 A will flow. (Settling
time: about 1 ms with pure resistance)
3.2 Set the test range
There are two types of range settings: manual range and automatic range. The automatic range
instrument will automatically select a suitable range for testing according to the value of the
measured resistance.

12/25
Manual range setting:
Enter the parameter setting interface, press the up and down keys to display the range, press the
right key to switch the range, and press the enter key to complete the setting. Even when the auto
range function is turned on, the manual range switching is effective (when the auto range is turned
on and the range is switched manually, the auto range function is automatically turned off).
Range:
AUTO ↔ 2MΩ ↔ 20MΩ ↔ 200MΩ ↔ 2000MΩ
Automatic range setting:
In the measurement interface, press the right button to switch the auto range. When set to auto
range, the [AUTO] mark lights up. When the auto range function is turned off, the [AUTO] mark
is not displayed.
Note:
• If the range is changed while the auto range is ON, the auto range is automatically canceled and
it becomes the manual range.
• If the comparator function is set to ON, the range is fixed and cannot be changed. To change the
range, set the comparator function to OFF or change the range in the comparator setting.
• The auto range may become unstable due to the measured object. In this case, specify the range
manually or increase the delay time. For the measurement accuracy of each range, refer to
"Resistance Measurement Accuracy".
3.3 Setting the test speed
In the parameter setting interface, press the up and down keys to move the cursor to speed, you
can switch the current test speed. The time is 500ms. In the test environment, the electric field
interference is relatively large, or the test is difficult to stabilize, it is recommended to use the slow
test.
Note:
• When the abnormality detection function is turned on, the fast sampling time is extended to
100ms, and the slow sampling time is unchanged at 500ms.
• If the sampling period is 500ms during slow test, if the setting of the test period is less than
500ms, the test result will not be displayed. This requires the test cycle time to be set longer than
the sampling cycle.

15/25
Note:
• [L.FAIL] and [F.FAIL] light up at the same time when the test value and sorting value are out of
the range and no valid judgment can be made.
3.6 Short-circuit detection function
Short-circuit detection function is used to judge whether the DUT is short-circuited before the
insulation test. The high voltage of the test output may burn out the metal defects that cause the
short circuit. If you want to avoid this, you can use the short circuit detection function. The
short-circuit detection voltage is about 2 ~ 4V. When the DUT is a capacitive load, there is also a
charging time. There are also two modes for setting the charging time. One is the automatic mode.
By monitoring both ends of the DUT The voltage changes to determine whether the charge is fully
charged. The other is a fixed charging time。
