1. Preface

1.1 Product Overview

The 19020/19021/19022 Multi-Channel Sync Hipot Testers are high quality devices specially designed to test the hipot leakage current and insulation resistance automatically for electrical and electronic equipment.

For withstand voltage test, the output power of each channel for 19020/19020-4 is AC: 50VA(5kV, 10mA) /DC: 30VA(6kV, 5mA), for 19021/19021-4 is AC: 48VA(6kV, 8mA) and for 19022/19022-4 is DC: 28VA(8kV, 3.5mA). Thus they can be used to perform withstand voltage tests on electronic, electrical equipment as well as on components.

For insulation resistance test, the range it can show is 0.1MΩ ∼ 50GΩ and the test voltage is 50V~1000V that can be set as desired. (Note: Only 19021/19021-4 can conduct AC withstand voltage test.)

The Hipot Tester uses a clear display to show all settings, time, current, voltage, resistance and memory channel no., etc. without the need to memorize the parameters set previously.

The Hipot Tester has equipped the device to identify pass or fail products as well as to output signals of test result and to remote control other devices. It has GPIB, HANDLER and RS232 interfaces that are of advantage to automatic test system. This Tester equipped with assorted devices mentioned above is capable of performing highly efficient and accurate tests for electrical, electronic equipment and components.

1.2 Features

■ Sync Withstand Voltage Test

The testers have the world’s first sync withstand voltage test function that a single device can have 10 channels to output and test simultaneously and maximum 10 devices can be controlled (master & slave) for 100 channels. They can be grouped for output to avoid voltage difference from generation due to adjacent test and furthermore to improve the production efficiency.

■ Multiple Tests

The testers are able to select single test function such as AC withstand voltage test, DC withstand voltage test, Insulation Resistance (IR) test and Open/Short Check (OSC) test

■ OSC (Open/Short Check)

The testers have built-in OSC function to check if there is any Open (bad connection) or Short (UUT shorted) occurred during test. It may cause the Fail product to be identified as Pass if Open occurs. If Short is detected and resolved early when occurred, it can reduce the damage to fixture and save the test cost.

User’s Manual

■ Clear Display

The testers have a clearest design for display. All programs for settings such as test voltage, current state, test readings, test steps and test states are able to be viewed from the LED display directly.

■ High/Low Limit Comparison for Pass/Fail Products

The testers have been designed to do High/Low Limit comparison for the Unit Under Test (UUT.) This function is available in Withstand Voltage test or Insulation Resistance test. The low limit comparison for hipot and high limit comparison for insulation are used to test if there’s any bad connection or loose test wire that causes misjudgment.

■ Remote Control

The HANDLER of the testers is able to extend the control signals for controlling externally. It usually connects to the control box of automated devices.

■ Change Voltage Ramp Time

These testers have a [RAMP] function that can set the time required for voltage rises from zero to set value.

■ Change Voltage Fall Time

These testers have a [FALL] function that can set the time required for voltage falls from set value to low when the test time ends.

■ Auto Switch Low Current Range

The current meter ranges for withstand voltage test in the testers have two ranges, one is low AC range 0~2.999mA and the other is 3.00 mA ~ maximum AC. There are three ranges for DC: 0~299.9uA low current range, 0.300mA ~2.999mA current range and

3.00~ maximum AC. If the tested current is low, software can be used to switch the current range to low range automatically for resolution improvement before the test ends as need.

The 19021 and 19021-4 hipot testers have 4 AC ranges which are 30uA, 300uA,

3.000mA and 8.0mA. If the tested current is low, it can use software to set if automatically changing the current range to low range before the test ends, so that the resolution can be increased.

3. Precaution before Use

The Hipot Tester can output up to 8kV high voltage for external test. Accidents may occur or even cause death if using this Tester incorrectly or in the wrong way. Thus for safety sake, be sure to read the precautions in this chapter to avoid any accidents from happening.

1. High voltage module replacement

If users replace or switch the high voltage modules on the rear panel, to ensure the Tester output is still within the specification, users need to recalibrate the Tester and ensure the specification.

2. Electric shock

To prevent the incident of electric shock from occurring, it is suggested to wear the insulated rubber gloves before using the Hipot Tester for electricity related tasks.

3. Grounding

A safety ground terminal is located at the rear of the Tester chassis; please use a proper tool to ensure it is grounded accurately. If not it would be very dangerous when the power circuit or the connection cable of any device shorts with ground terminal as the chassis may contain high voltage. Anyone who touches the device in this case may cause electric shock. Therefore, it is necessary to connect the safety ground terminal to earth properly as the arrow shows in Figure 3-1.

Figure 3-1

4. Connecting test cable to LOW terminal

It is necessary to check if the test cable is connected all the time when the Tester is in use. When connecting a test unit with test cable, connect the RTN/LOW test cable to the UUT first. When the host RTN/LOW terminal is connected, it is very dangerous if the test cable on RTN/LOW terminal is not connected correctly or falls as the entire UUT may full of high voltage.

5. Connecting the test cable to high voltage output terminal

When the RTN/LOW test cable is connected, follow the steps below to connect the high voltage output cable.

Multi-Channel Sync Hipot Tester 19020/19020-4/19021/19021-4/19022/19022-4

3-2

User’s Manual

․ Press STOP. ․ Ensure the DANGER indicator is off. ․ Short the test cable of RTN/LOW and high voltage output to make sure there is no

voltage output.

․ Plug in the high voltage test cable to high voltage output terminal. ․ Last connect the RTN/LOW test cable to the unit under test and then connect high

voltage test cable.

6. End the test

When the test is end or the Tester is not in use or is in use but needs to leave it unattended for a while, it is necessary to toggle the power switch to О (i.e. to shut off the power) as Figure 3-2 shows.

Figure 3-2

7. Do not touch the hazard areas when the Tester is in test mode

When the Tester is in use, touching the object with high voltage such as UUT, test cable, probe and output terminal is very dangerous.

8. Ensure the test is done

Sometimes users might need to touch the high voltage objects such as UUT, high voltage test cable or output terminal etc. due to configuration or test required change. In that case, please ensure the following:

∗ The power switch is turned off. ∗ The UUT may full of high voltage when completing the Insulation Resistance

test; thus it is necessary to follow the description of item 9 and 10 for execution.

<<< Warning! Charging when doing insulation resistance test >>>

9. Charging

When doing insulation resistance test, the UUT, capacitor, test cable, probe and output terminal, even the Tester itself may full of high voltage. The charged voltage may need some time to discharge completely after turning off the power switch. It is necessary to

/−

follow the instruction described above for actions. Do not touch any area that may cause electric shock especially when the power is just turned off.

10. Ensure the charged voltage is fully discharged

The time required for fully discharging the voltage depends on the test voltage applied and the features of UUT. Assuming the high voltage added on the UUT equals the high voltage added to a 0.01uF capacitor and paralleled to a 100MΩ resistance circuit. When the test voltage is 1000V, then it requires approximately 3.5 seconds for the voltage that added to test and on UUT to fall to 30V under after turned off the power. For 500V test voltage, it requires about 2.8 seconds. Assuming the time constant of a UUT is already known, the way described above can be used to calculate the time required for voltage falling to 30V under after powered off by timing the time constant multiple to the time decreased to 30V under as Figure 3-3 shows.

Calculation: Vo

Figure 3-3

11. Remote controlling the Tester

The Hipot Tester can be remote controlled generally for high voltage output via external control signal. When performing it, it is necessary to follow the control guidelines for safety and precautions.

∗ Do not allow any accidental high voltage output that may cause hazard. ∗ When there is high voltage output from the Tester, do not allow any operator

or other personnel to touch the UUT, test cable or probe output and etc.

12. Turning on or off the power switch

Once the power switch is turned off, it needs to wait for a few seconds to turn it on again. Do not power it on and off continuously to avoid occurring errors. It is very dangerous to power it on and off continuously when in high voltage output state in particular. When

turning on or off the power, the high voltage output terminal cannot connect to any object to avoid the hazard caused by abnormal high voltage output.

13. Other notices

Do not short-circuit the output line, grounding wire, communication cable or other device’s grounding wire or AC power to avoid charging the entire Tester to dangerous voltage. To short-circuit the terminal of high voltage output and LOW, it is necessary to ground the Tester chassis to earth properly.

Be sure to use the fuse with correct specification or it may cause hazard.

CAUTION

User’s Manual

<<< Emergency Case >>>

14. Process for emergency case

To avoid causing bigger hazard when in emergency situations like electric shock, UUT or Tester burnout, please perform the steps below:

∗ First cutoff the power switch. ∗ Second unplug the power cord.

<<< Resolving Problems>>>

15. Problems occurred

Problems occurred in the following situation are very dangerous. The output terminal may still have high voltage output even the STOP key is pressed; therefore, users should be extremely careful when dealing with it.

․ The DANGER LED indicator keeps on when STOP key is pressed. ․ The DANGER LED indicator is on but the voltage meter has no readings.

When the above situation occurs, shut down the power and unplug the AC power cord immediately. Do not use the device again as failure is awfully hazardous. Please send the hardware back to Chroma or its distributor for repair service.

16. DANGER Indicator failure

When pressing the START key the voltage meter has readings but the DANGER LED indicator is still off, it means the indicator may be broken. Please power off the hardware and replace it with another device, then send the broken one back to Chroma or its distributor for repair service.

17. AC INPUT used by the Tester is 100V~240V auto switch and the fuse specification is

15A Slow/250V. Also to avoid electric shock the fuse should be changed when the

power cord is not plugged in. When replacing, use a flat screwdriver to pry the fuse holder inside the power socket and remove the fuse to replace with a new one by pushing it in gently, and then push the power socket back to its position.

18. Tester is normally operated under AC power

If the selected voltage range for local power supply is unstable, it may cause the device to work inaccurately or abnormally. Thus, please use appropriate equipment such as a power supply regulator to convert it to a suitable one.

19. Tester uses a power transformer with 1100VA or above

When the device to be tested draws a great deal of current, the current (about 10amp) may flow in for more than 10ms before judging for defect item and cutting off the output current. The same situation may occur before test, thus it is necessary to watch out the power cord capacity and the connecting cables used for other instruments or devices.

20. Storage

The temperature and humidity for the Tester is 5°C~35°C, 70% RH in normal. The operation may malfunction if exceeding the range. Do not mount the Tester to a fixed place in case it needs to be removed. The storage temperature for the Tester is from

4.8 Conducting the Test

4.8.1 Connecting the UUT

First ensure there is no voltage output and the DANGER LED is off. Connect the low potential test cable (black) to the Tester RTN/LOW terminal. Short-circuit the test cable and high voltage output terminal and ensure there is no high voltage output. Next, plug in the high voltage test cable (red or white) to high voltage output terminal. Then connect the low potential test cable to UUT and the high potential test cable to UUT.

4.8.2 Procedure for AC/DC Test

1. Connect the UUT properly following the connection method.

2. In the power on screen shown below:

Illustration: TEST 1/2 means there are 2 test steps and it is running the 1

test step at present. AC indicates the test mode. “Position 1” indicates the set voltage, “Position 2” is the high limit set for current, while “Position 3” is the test result.

3. Press STOP to prepare for test. The status line shows “STANDBY”.

4. Press START to activate the test When this key is pressed it starts to output voltage and the DANGER LED is on. The status line shows a counter to count down. “Position 1” will show the output voltage value, “Position 2” will show the current readings and “Position 3” will show the test result.

5. GOOD Judgment When all tests are done and the results show PASS, the Tester will see the UUT as a GOOD product and cutoff the output. The HANDLER interface outputs PASS signal and the beeper acts at the same time.

6. NO GOOD Judgment

If the test value is abnormal, the Tester judges it as FAIL and cutoff the output

4.8.7 Hardware/Software AGC

AGC function is used due to load effect (the output voltage changes when the Load changes.)

ACV : H/W AGC always ON, S/W AGC default is ON but can be set to OFF. DCV : H/W AGC always ON, S/W AGC default is ON but can be set to OFF. IR : No H/W AGC, S/W AGC is ON but can be set to OFF. OSC : No H/W AGC, S/W AGC is OFF.

When the ACV/DCV test time is less than 0.29 second, the H/W AGC is OFF.

RLVo

User’s Manual

Vs Vo / Vs = RL / (Rs + RL)

1. H/W AGC: Since the load effect caused Vo<Vs, the hardware comparator circuit is used to make Vo compensate voltage to be the same as within Vs within 0.1sec.

2. S/W AGC: This tester uses software AGC only in IR MODE. Since the software compensation is slow, it would not cause transient voltage shock to DUT and the common IR impedance (R thus Vo ≒Vs.

L) is much larger than the output impedance (Rs) of this tester,
