Text and Images for Operation of Hi-Pot Cable Harness Testers

Test Spec

This is a harness tester NMG+.
The operation of NMK is the same as that of NMG+.
Please turn on it. MENU is displayed.
Let's set the test spec.
Please select No.3 function to set the test spec.
You can set the test specs for creating test data.
You can finish the settings after you select all specs with the set button.
If you quit it in the middle with the escape button, it will not be reflected.

Sampling

Let's create test data.
The operation is common to these models.
Please select No.2, Sampling.
Sampling is the function to read the wiring of the test target and create test data by combining it with the test spec you set.
Please connect test target to the tester and press set button to read the wiring.

Reading is completed.
You can check wires by turning the dial.
After your confirmation, move on by pressing set button.
Select the data number and name the new data.

Test

Let’s test with the new data.
Please choose the No.1 Test, on the menu.
You can see the data memorized in the device.
Start the test to press the set button.
If the test passes, it shows OK.

After the test fails, it shows NG.
Then you can check the detail by turning the dial.
In the NG result,
Slash mark / means open. hyphen mark - means short.
In the resistance test NG, the resistance values are displayed.
In the withstand voltage test NG, the leakage current values are displayed.
In the insulation resistance test NG, the resistance values are displayed.

Test:Start Mode

While the machine showing test start, you can change the start mode by turning the dial clockwise.
You can choose Manual, OK wait, After 1 to 10 seconds start.
In particular, OK wait is useful function to conduct the same test consecutively.
After the test starts by set button and finished with OK,You can start the test by only connecting the new cable.
This function helps you test data quickly.

Test:Spec Change

After creating test data, you may need to modify the data.
Then please select the data from ”test”.
Please turn the dial counterclockwise while the tester showing the test start.
You can open Spec change mode.
Please set the spec again.
You can finish the settings after you select all specs with the set button.

Test:Moment Disconnection Testing

If you conduct the Moment Disconnection Testing,
You need to add the impacts by hitting or pulling.
As an example, let's test in the mode monitoring the disconnection until the set button is pressed.
After applying the specified impact, press the set button.
If no disconnection occurs, OK is displayed.
If a disconnection is detected, NG is displayed.

Search

Search is the function to check or test the connection by touching with the probe.
SCAN is for just checking the pin you touch with the probe.
TEST is for the test with search test data.
Let's check SCAN.
There are two modes, HOLD and UNHOLD.
You can choose whether or not to keep the last pin touched on the display.
It's useful for checking the continuity of jigs and so on.
Hi-Pot Cable Harness Testers_Search Testing
Let's create search test data.
Please click register. (REG.)
Touch the pins for reading the wiring.
Check the pins and click register to save data.
The name should be percent or ampersand for the first letter.
Percent "%" is set for order search. You must touch the registered pins in the order to progress the test.
Ampersand "&" is set for random search. You can touch the registered pins at random order and progress the test.
Let's open the test data.
Start the test.
When you touch all pins registered, the test is passed.
You can't find the pins, please press ESC button to stop the Test.

Function

Let's check the function.
You can set Start mode at Function 2.
You can set Printer setting at Function 3.
You can set the OK-sound and NG-sound at Function 4
It makes it easier to distinguish when two or more inspectors are working next to each other.
You can select the language at Function 5
You can set the date at function 6
You can select the terminal display mode at function 7.
You can set the output for the impactor at function 8.
Please contact us about PLC operation.This is available by customization.

Self-Check

Self check is the function to check the tester itself.
Please conduct test for the daily check.
Remove the all test cables from the tester connectors before click TEST.
It shows "pass".The tester is normal.
If NG occurs, please check your environments.
Please contact us in case of tester failure.
