Calls attention to a procedure, practice, or condition that could possibly cause damage to equipment or permanent loss of data.

1.3. Glossary of Terms

(As used in this manual)

Alternating Current, AC: Current that reverses direction on a regular basis. Utility power is

usually generated in the form of a sinusoid at a frequency of 60 times per second in the United States and 50 times per second in other countries.

Arc: A partial momentary breakdown due to the force of a strong electric field on closely spaced

conductors, sometimes evidenced by corona or a luminous flashover.

Breakdown: The failure of insulation to effectively prevent the flow of current. If the test voltage is

gradually raised, breakdown will begin suddenly at a certain voltage level and current flow will not be directly proportional to voltage. Once a breakdown occurs, especially for a period of time, the next gradual application of voltage will often cause a breakdown to begin at a lower voltage.

Conductor: A solid or liquid material which permits the flow of electrons. A material which has a

volume resistivity of no more than 103 Ω-cm.

Current: The movement of electrons through a conductor. Current is measured in amperes (A),

milliamperes (mA), microamperes (uA). Symbol = I

Dielectric: An insulating material that is positioned between two conductive materials in such a way

that a charge or voltage may appear across the two conductive materials.

____________________________________________________________________________

Direct Current, DC: Current that flows in one direction only. The source of direct current is said to

be polarized and has one terminal that is always at a higher potential than the other.

Frequency: The number of cycles an AC waveform repeats over time. Usually given in Hertz (Hz). Ground: Refers to the point of low potential in a circuit to which all other voltages are referenced.

May or may not be tied to the earth. Also referred to as Earth.

Hot: Used to refer to the test lead or output side of an instrument that is at high potential. Impedance: The property of capacitive or inductive items to limit certain frequencies.

Insulation: Gas, liquid or solid material which has a volume resistivity of at least 10

Ω-cm and is

used for the purpose of restricting current flow between conductors.

Leakage: AC or DC current flow through insulation and over its surfaces. Current flow is directly

proportional to voltage. The insulation is thought of as a constant impedance unless breakdown occurs.

Neutral: The point of low potential in a circuit to which all other voltages are referenced. Also known

as Common.

Peak Current: The maximum amplitude of an AC current waveform. For a sinusoid, 1.414 x the

RMS value.

Power: The amount of work performed by an energy source over time, given in Watts (W). PF (Power factor): Power Factor = W/VA where W =Watts (Real Power) and VA =Volts x Amps

(apparent power). It is important to note that the closer the power factor is to "1" the more resistive the DUT is. The closer the power factor is to 0 the more reactive (inductive or capacitive) the DUT is.

Reactive Current: The current component due to the reactive impedance of a load. Also called

imaginary current.

Real Current: The current component due to the resistance of a load. Resistance: The property of a substance that impedes current and results in the dissipation of

power in the form of heat. The practical unit of resistance is the ohm (Ω). Symbol = R

Return: The path by which current returns to a source. RMS: The Root Mean Squared value of a voltage or current waveform. An RMS waveform delivers

the same amount of energy to a load as a DC waveform of the same value. For a sinusoid, the RMS value is .707 x the peak value.

Total Current: The vector sum of the real current component and the reactive current component

produced by an applied voltage.

HypotMAX produces voltages and currents that can cause harmful or fatal electric shock. To prevent accidental injury or death, these safety procedures must be strictly observed when handling and using the test instrument.

Associated Research, Inc. will not be held liable for injuries suffered if the instrument is not properly maintained and safety checked annually. See section 1.1. Warranty

Policies for more information.

1.4.2. Test Station Location

Select an area away from the mainstream of activity where employees do not walk while performing their normal duties. If this is not practical because of production line flow, then the area should be roped off and marked for HIGH VOLTAGE TESTING. No employees other than test operators should be allowed inside.

If benches are placed back-to-back, be especially careful about the use of the bench opposite the test station. Signs should be posted: “DANGER – HIGH VOLTAGE

TEST IN PROGRESS – UNAUTHORIZED PERSONNEL KEEP AWAY.” Work Area

When possible, use the instrument on a non-conducting table or workbench. If you cannot avoid using a conductive surface, be certain that it is connected to a good earth ground and the high voltage connection is insulated from the grounded surface.

There should not be any metal in the work area between the operator and the location where products being tested will be positioned. Any other metal in the work area should be connected to a good ground, never left “floating”.

Keep the area clean and uncluttered. All test equipment and unnecessary test leads should be removed from the test bench and put away. It should be apparent to both the operator and to any observers which product is under test, which product is waiting to be tested and which product has already been tested.

Power

Power to the test station should be arranged so that it can be shut off by one prominently marked switch located at the entrance to the test area. In case of an emergency, anyone should be able to cut off the power before entering the test area to offer assistance.

More Information For more information on setting up a safe work station, please visit the Events and Training section of our website at http://www.asresearch.com/events-

training/Default.aspx

Electrical safety tests should not be performed in or around ESD testing areas. ESD methods should not be employed during electrical safety testing, as this could cause a hazardous condition for equipment and test operators.

KEY SAFETY POINTS TO

REMEMBER

1.4.3. Test Operator

This instrument generates voltages and currents that can cause harmful or fatal electric shock and must only be operated by a skilled worker trained in its use. The operator should

understand the electrical fundamentals of voltage, current, and resistance.

Do not touch the device under test, high voltage test lead, alligator clip, or clip insulator once the test has been started.

Do not touch the front panel when testing or after a malfunction has occurred.

Rules

Operators should be thoroughly trained to follow all national safety standard guidelines for electrical safety testing in the workplace. Defeating any safety system should be considered a serious offense with severe penalties. Allowing unauthorized personnel in the area during a test should also be dealt with as a serious offense. Test operators should be familiar with methods to properly discharge a device under test in case test leads become disconnected during testing.

Refer to the following standards for more information:

NFPA 70E OSHA 1910 subpart (S) EN50191

Dress

Operators should not wear jewelry that could accidentally complete a circuit.

ESD protocols should not be observed while

performing electrical safety tests. Intentionally grounding the test operator could lead to a harmful or

fatal electric shock. Medical Restrictions

Personnel with heart ailments or devices such as pacemakers should be informed that the voltages and currents

Keep unqualified and

The mains plug is used as the disconnecting device and shall remain readily operable. The socket-outlet shall be installed. Near the equipment and shall be easily accessible.

2.2.2. Power Requirements

This instrument requires a power source of either 115 volts AC ± 10%, 50/60 Hz single phase or 230 volts AC ±10%, 50/60 Hz single phase. Before applying power verify that the instrument is set to the correct line voltage (115 or 230 volts). Adjust the voltage select switch to 115 for use with a 115 volt input. Adjust the voltage select switch to 230 for use with a 230 volt input. See section 3.2.2. Rear Panel Controls for an image of the rear panel.

Do not replace the power supply cord with an improperly rated cord. For North American: A UL listed and CSA labeled power

cord must be used with the instrument in the United States and Canada. The power cord must include a NEMA5-15 style male plug, SVT or SJT cord sets, and be rated for at least 125VAC, 10A, number 16 gauge (or 125VAC, 15A, number 14 gauge) wire or larger, and the length of the cord does not exceed 2 m must be used. For European: A certified power supply cord not lighter than light PVC sheathed flexible cord according to IEC 60227, designation H03 VV-F or H03 VVH2-F (for equipment mass not exceeding 3 kg), or H05 VV-F or H05 VVH2-F2 (for equipment mass exceeding 3 kg), and be rated for at least 3G 0.75 mm² (for rated current up to 10 A) or 3G 1.0mm² (for rated current over 10 A up to 16 A) wire or larger, and the length of the cord does not exceed 2 m must be used.

Do not switch the line voltage selector switch located on the rear panel while the instrument is on or operating. This may cause internal damage and represents a safety risk to the

4.2.5. Smart GFI

Press the SETUP key to advance the menu to the Smart GFI parameter. The display will show:

Use the ENTER key to toggle the Smart GFI ON and OFF. The high voltage power supply of the HypotMAX is internally referenced to earth

ground. Since the leakage current measuring circuit of the instrument monitors only current that flows through the return lead the possibility exists for current to flow directly from the high voltage output to earth ground without being measured. The SmartGFI (Ground Fault Interrupt) circuit monitors the current between the high voltage output and earth ground. Therefore, if the operator touches the high voltage lead and earth ground, the instrument will detect this hazardous condition and shut off immediately.

SmartGFI goes beyond a standard GFI circuit by automatically determining the return configuration of the DUT (grounded or floating) and enabling or disabling depending on the situation. When the HypotMAX’s Return lead is floating, the SmartGFI circuit enables, protecting the test operator from electric shock. When the HypotMAX’s Return lead is earth grounded, the SmartGFI circuit disables and the instrument operates in a grounded return mode of operation. If the GFI were to remain active in this state, the tester would continuously fail since all current is returning through earth ground. By disabling the SmartGFI circuit and operating in a grounded return mode, HypotMAX allows the user to perform tests on devices that have their chassis’s earth grounded by the test fixture or test environment.

Toggle the Smart GFI function or press the SETUP key to forward to the GPIB address selection. Press the EXIT key to return to the operation mode. The program will store the Smart GFI setting automatically.

Use the ENTER key to toggle the remote command set between 488.1 and 488.2. Please refer to section 7.0. Bus Remote Interface USB/GPIB/RS232 for additional information about this selection.

Change the BUS Remote Command Set again or press the SETUP key to advance to the Memory Lock parameter. Press the EXIT key to return to the operation mode. The program will store the BUS Remote Command Set automatically.

4.2.8. Memory Lock

Press the SETUP key to advance the menu to the Memory Lock parameter. The display will show:

Use the ENTER key to toggle the Memory Lock ON and OFF. Memory Lock is a sub-function of the Lock setting. In order for the Memory Lock

function to work, the Lock must first be turned ON. Selecting the Memory Lock OFF will allow the user to access all available Memory locations but restricts access to memory editing capabilities. Selecting the Memory Lock ON will allow the user to only run the currently loaded memory.

5. OPERATING INSTRUCTIONS

5.1. Instrument Connections

Before the operation of this instrument, make sure that all Test Parameters have been set properly according to the Test Parameters Setup Procedures. Also, check the system setting of Remote Control, LCD Contrast, the Alarm Volume, and Fail Stop.

Be sure to connect the appropriate test leads to the device under test (DUT) or test fixture. Be sure to connect the safety ground (on the rear panel) to a suitable known good ground before energizing this instrument. Then connect the return lead first to the test fixture or the DUT followed by the high voltage lead.

Please check your connections to be sure they are making good contact. Clear the area of any debris that may create a hazardous situation and ask any unnecessary personnel to leave the area.

DO NOT TOUCH THE DEVICE UNDER TEST, HIGH VOLTAGE TEST LEAD, ALLIGATOR CLIP, OR CLIP INSULATOR ONCE THE TEST HAS BEEN STARTED.

DO NOT TOUCH THE FRONT PANEL WHEN TESTING OR AFTER A MALFUNCTION HAS OCCURRED.

This instrument is supplied with a high voltage test lead terminated with an alligator clip. This clip is designed to allow firm connection to the DUT without the need for an operator to hold a probe or lead in place during the test. This clip and insulator will carry the voltage and current of this tester but they are not intended to be held by the operator during the test while the high voltage is energized. Please insure that you do not make contact with the alligator clip or the clip insulator while high voltage is energized.

Interlock Connector

HypotMAX is equipped with a Remote Interlock feature. Remote Interlock utilizes a

set of closed contacts to enable the instrument’s output. If the Remote Interlock

contacts are open the output of the instrument will be disabled. To disable the Remote Interlock feature connect the Interlock Key into the Signal Input port located on the back of the tester.

5.2. Settings Screen

The settings screen will show parameter settings of the test that will be performed and the memory location that they are stored in. This screen can be accessed after a test is Aborted or Passed by pressing the RESET button or after a test failure by pressing the RESET button twice. The following is an example of a Settings Screen for the 7720 before any test has been executed.

M XX: Memory Program number Set: Withstand Voltage test setting screen XXX.X s: Dwell Time setting X.XX KV: Output Voltage setting X.XXX mA: High-Limit current setting (AC withstand instruments) XXXX A: High-Limit current setting (DC withstand instruments)

The Settings screen is the main operational screen of instrument. From this screen, test parameters are monitored while the test is being performed.

5.3. Performing a Test

1. From the Settings screen, press the MEMORY key and select the memory you wish

to perform using the numeric keypad then press the ENTER key to return you to the Perform Test screen.

2. Attach the appropriate load or DUT to the instrument.

DO NOT TOUCH THE DEVICE UNDER TEST, HIGH VOLTAGE TEST LEAD, ALLIGATOR CLIP, OR CLIP INSULATOR ONCE THE TEST HAS BEEN STARTED.

3. Press the TEST button.

4. The instrument will now perform the test or connected sequence of tests.

5.3.1. Discharge Function in DC units

The 7710 and 7720 units are equipped with a Discharge function that is designed to discharge the voltage of a capacitive DUT so that it may be safely disconnected from the test leads of the instrument. The discharge function monitors the voltage of the DUT and remains active until the voltage of the DUT falls below 40 volts. The instrument will also not allow another test to be executed until the voltage of the DUT falls below 40 volts. The discharge period will occur either directly after the Dwell time, if Ramp-DOWN is set to “0”, or after the designated Ramp-DOWN time.

____________________________________________________________________________

During the Discharge time, the display will show:

If the capacitance of the DUT is very small it is possible that you will not see this display due to the short amount of time required to discharge the DUT.

The voltage and time of discharging DUT will be displayed during the discharge period but this information is only intended for reference and cannot be reviewed after the end of the discharge period. The process signal of the remote I/O remains active during the discharge period and the high voltage lightning bolt indicator on the front panel of the instrument is also active during the discharge period.

As a safety precaution, if the RESET button is pressed during the discharge period, the instrument will log the RESET but will not discontinue the discharge function. Pressing the RESET during the discharge will only prevent a connected memory from executing after the discharge time.

The capacitance of the DUT should never exceed the maximum specification listed in this manual.

DO NOT TOUCH THE DEVICE UNDER TEST, HIGH VOLTAGE TEST LEAD, ALLIGATOR CLIP, OR CLIP INSULATOR DURING THE DISCHARGE CYCLE.

5.3.2. Connected Memory indicator

The connected memory indicator is an underscore symbol located directly next to the Memory number and only will be displayed when the connect function has been turned ON in the Test parameters.

5.3.3. Manual Voltage Adjustment

When HYPOTMAX is performing a test, the  and  keys may be used to adjust the output voltage.

Pressing the  key will increase the output voltage, pressing the  key will decrease the output voltage. Manual voltage adjustment temporarily overrides the voltage setting and only remains in effect until the test is terminated by Pass, Fail, or Abort.

When the Lock parameter is selected ON in the system menu, manual voltage adjustment is disabled.

5.4. Reviewing Test Results

The method for reviewing test results is to press the ENTER key at the end of the test sequence. Results can be reviewed at any time before the next test is executed by pressing the ENTER key and then scrolling with the up and down arrow keys or repeatedly pressing the ENTER key. The results of the last test in the process will be followed by the first test when scrolling through the results. All buffers are cleared at the start of the next test cycle.

Pressing the EXIT or RESET key will return you to the Settings screen.

5.5. Test Messages

corrupted.

5.9. Output Error

If the instrument has an internal problem and the TEST button is pressed, the Output Error screen will appear as follows:

The RESET button is not active while this screen is displayed. To clear this screen and return to test mode the EXIT key must be pressed. When the EXIT key is pressed, the instrument will continue with its normal failure indication process. The failure light and Alarm can then be cleared by pressing the RESET button. This message appears on the display after exiting from the Output Error screen.

If this error message appears please call Associated Research, Inc. immediately at 1800-858-TEST (8378).

6. CONNECTION OF REMOTE I/O

Two 9-pin “D” type connectors are mounted on the rear panel and provide REMOTEINPUT-OUTPUT control and information. These connectors mate with standard 9 pin D-sub-miniature connector provided by the user. The output mates to a male (plug) connector while the input mates to a female (receptacle) connector. For best performance, a shielded cable should be used. To avoid ground loops the shield should not be grounded at both ends of the cable. Suggested AMP part numbers for interconnecting to the Remote I/O are shown below:

205204-4 PLUG SHELL WITH GROUND INDENTS 205203-3 RECEPTACLE SHELL 745254-7 CRIMP SNAP-IN PIN CONTACT (for plug) 745253-7 CRIMP SNAP-IN SOCKET CONTACT (for receptacle) 745171-1 SHIELDED CABLE CLAMP (for either plug or receptacle) 747784-3 JACKSCREW SET (2)

6.1. Signal Outputs on Remote I/O

The rear panel connector provides three output signals to remotely monitor PASS, FAIL, and PROCESSING conditions. The monitoring signals are provided by three normally open internal relays that toggle on and off to indicate the condition of the tester. These are normally open free contacts and will not provide any voltage or

____________________________________________________________________________

The Remote Signal Input connector may be used with various accessories, including light curtains, foot switches, and safety probes. Contact Associated Research, Inc. for more information.

DID YOU KNOW?

current. The ratings of the contacts are 1 AAC / 125 VAC (0.5 ADC / 30 VDC). The signal outputs are provided on the 9-pin female D connector. Below is a listing that indicates what conditions activate each pin. When a terminal becomes active, the relay closes thereby allowing the external voltage to operate an external device.

Pins 1 and 2 provide the PASS signal. Pins 3 and 4 provide the FAIL signal. Pins 5 and 6 provide the PROCESSING signal.

The following describes how the relays operate for each test condition: PROCESSING – The relay contact closes the connection between pin (5) and pin (6)

while the instrument is performing a test. The connection is opened at the end of the test. The process contact is closed all the way through to the end of the discharge cycle in DC units.

PASS – The relay contact closes the connection between pin (1) and pin (2) after detecting that the item under test passed all tests. The connection is opened when the next test is initiated or the reset function is activated.

FAIL – The relay contact closes the connection between pin (3) and pin (4) after detecting that the item under test failed. The connection will open when the next test is initiated or the reset function activated.

6.2. Signal Inputs of Remote I/O and Memory Access

The HypotMAX remote connector enables remote operation of the TEST, RESET, and REMOTE INTERLOCK functions, and allows the operator to select Memory 1, Memory 2, and Memory 3.

When the PLC Remote mode is on, the HypotMAX will respond to simple switch or relay contacts closures. A normally open momentary switch can be wired across pins 3 and 5 to allow remote operation of the TEST function. A minimum pulse width or contact closure of 20mS is required to guarantee a test start. A normally open momentary switch can be wired across pins 2 and 5 to allow remote

operation of the RESET function. A minimum pulse width or contact closure of 50mS is required to guarantee that a running test will abort. When the PLC remote function is (ON) the TEST switch on the front panel will be disabled to prevent a test from being activated through this switch. For safety, the front panel RESET switch remains active even when a remote reset switch is connected so that high voltage can be shut down from either location.

The HypotMAX also allow access to three MEMORY PROGRAMS through the remote control connector. This gives the user the capability to quickly change parameters and initiate a test remotely. The built in memory programs of the instrument are used to accomplish this. Three internal memory programs can be accessed, by connecting terminals 7, 8, and 9 in different combinations. The memory select lines should be set simultaneously and remain set for a minimum of 20ms to guarantee that the correct memory will be selected. However, the memory select bits may be set in sequential manner, provided that the time delay between each bit is less than 4ms. When the desired bit pattern has been established it should remain set for a minimum of 20ms to guarantee that the correct memory will be selected. It may be necessary to "OR" the momentary switches (relay contacts) to prevent incorrect program selection due to timing errors.

THAT MEMORY

DO NOT CONNECT VOLTAGE OR CURRENT TO THE SIGNAL INPUTS, THIS COULD RESULT IN DAMAGE TO THE CONTROL CIRCUITRY.

MEMORY ONE – Momentarily connecting terminal 7 to 8 signals the instrument to immediately begin the test program that is stored in memory one.

MEMORY TWO – Momentarily connecting terminal 7 to 9 signals the instrument to immediately begin the test program that is stored in memory two.

MEMORY THREE – Momentarily connecting terminal 7 to terminals 8 and 9 signals the instrument to immediately begin the test program that is stored in memory three.

Remote Interlock

HypotMAX is equipped with a Remote Interlock feature. Remote Interlock utilizes a set of closed contacts to enable the instrument’s output. If the Remote Interlock contacts are open the output of the instrument will be disabled. Remote Interlock could also be referred to as a remote system lockout, utilizing “fail when open” logic. If the Remote Interlock contacts are open and the TEST button is pushed, a pop-up message will be displayed on the screen for two seconds. The message will appear as follows:

____________________________________________________________________________

If the Remote Interlock contacts are opened during a test, the pop-up message will be displayed and the test will abort. The hardware and has been configured to provide the interlock connections on pins 4 and 5 of the Remote Interface, Signal Input port. The instrument can still be used without the external interlock device as long as the Interlock Disable Key (38075 provided with unit) is plugged into the Remote Interface, Signal Input port. If there is nothing connected to the Remote Interface, Signal Input port to provide a connection to the Remote Interlock, the instrument will not perform tests.

PLC Remote Pop-up message

If you attempt to start a test from the front panel Test button and the PLC remote function is turned ON, a pop-up message will be displayed. The pop-up message will appear as follows:

7. BUS REMOTE INTERFACE USB/RS-232/GPIB

This section provides information on the proper use and configuration of the bus remote interface. The USB/RS-232 remote interface is standard on the HypotMAX but the GPIB (IEEE-488) interface option can be substituted for the USB/RS-232 interface. Please refer to section 8.0. Options for details on the HypotMAX options. The USB/RS-232 interface uses the same command set as the GPIB interface for setting test parameters; however, many functions of the GPIB 488.2 interface are not available through USB/RS-232. The IEEE-488 interface included with the HypotMAX conforms to the requirements of the IEEE-488.2 standard.

The USB/RS-232 interface card requires the user to download a driver in order for the instrument to recognize the USB interface. The driver can be found on the Associated Research, Inc. website:

http://www.asresearch.com/products/software/USB-driver.aspx

Click on “USB/RS-232 Driver” to download the driver. This link contains an automatic extract and install program. Follow the instructions of the installation program to initialize the driver install. NOTE: The USB port acts as a USB to RS-232 converter. As a result, the PC will recognize the USB port as a virtual COM port.

7.1. USB / RS-232 Interface

This interface provides all of the control commands and parameter setting commands of the GPIB interface with the exception of some of the 488.2 Common Commands and SRQ capability. All commands can be found in section 7.4. USB/RS-232/GPIB Command List. The identification command *IDN and the Status Reporting commands are also available through USB/RS-232.

7.1.1. RS-232 Connector

The RS-232 cabling should be configured as follows for a 9-pin serial port interface:

7.1.2. Communications Port Configuration

The COM port should have the following configuration:

9600 baud 8 data bits 1 stop bit

Instrument RS-232 Port PC / Bus Controller

5 TD

RDTDRD

SIG GND

____________________________________________________________________________

No parity

This interface does not support XON/XOFF protocol or any hardware handshaking. The controller should be configured to ignore the handshaking lines DTR (pin 4), DSR (pin 6) CTS (pin 8) and RTS (pin 7). If the port cannot be configured through software to ignore these lines the handshake lines should be jumpered together in two different sets. Pins 4 and 6 should be jumpered together and pins 7 and 8 should be jumpered together at the controller end of the cable.

7.1.3. Sending and Receiving Commands Sending Data

Once a command is sent to the instrument over the USB/RS-232 bus the instrument will send one of two responses. If the transfer was recognized and completed the instrument will return with 06 hex or 6 decimal, the Acknowledge (ACK) ASCII control code. If there is an error with the command string that is sent, the instrument will respond with 15 hex or 21 decimal, the Not Acknowledge (NAK) ASCII control code. The ACK or NAK response allows for software handshaking to monitor and control data flow.

Receiving Data

When requesting data from the instrument it will automatically send the data back to the controller input buffer. The controller input buffer will accumulate data being sent from the instrument, including the ACK and NAK response strings, until it has been read by the controller.

7.2. GPIB Interface

This interface is optional on the HypotMAX and provides all of the control commands and parameter setting commands of the USB/RS-232 interface along with 488.2 Common Commands and SRQ capability. All commands can be found in section 7.4.

USB/RS-232/GPIB Command List.

7.2.1. GPIB Connector

Connection is usually accomplished with a 24-conductor cable with a plug on one end and a connector at the other end. Devices may be connected in a linear, star or a combination configuration.

The standard connector is the Amphenol or Cinch Series 57 Microribbon or AMP CHAMP type. The GPIB uses negative logic with standard transistor-transistor logic (TTL) levels. When DAV is true, for example, it is a TTL low level ( 0.8 V), and when DAV is false, it is a TTL high level ( 2.0 V).

Restrictions and Limitations on the GPIB

A maximum separation of 4 m between any two devices and an average

separation of 2 m over the entire bus.

A maximum total cable length of 20 m.

No more than 15 device loads connected to each bus, with no less than two-thirds

powered on. For example 1 GPIB controller and a maximum of 14 GPIB instruments.

NOTE: A bus extender, which is available from numerous manufacturers, is

available to overcome these limitations.

7.2.2. GPIB Address Each device on the GPIB (IEEE-488) interface must have a unique address. You can set the address of the HypotMAX to any value between 0 and 30. The address can only be set from the front panel. The address is stored in non-volatile memory and does not change when the power has been off or after a remote reset.

The address is set to 8 when the instrument is shipped from the factory.

7.3. Interface Functions

The capability of a device connected to the bus is specified by its interface functions. These functions provide the means for a device to receive, process, and send messages over the bus. The interface functions are listed in the chart below.

7.4. USB / RS-232 / GPIB Interface Command List

Echo and Response Considerations USB/RS-232 Responses

The USB/RS-232 bus will automatically send any response back to the controller's input buffer.

GPIB Queries and Responses

The HypotMAX GPIB bus will not send any data to the controller without being queried. A GPIB read command must be sent after a command string to retrieve any data from a query command (?).

7.4.1. Rules for Sending Commands to the Instrument The following conventions are used to describe the commands syntax for HypotMAX:

Braces ({ }) enclose each parameter for a command string. Triangle brackets (< >) indicate that you must substitute a value for the

enclosed parameter. The Pipe ( | ) is used to separate different parameter options for a command. The command and the parameter data must be separated with a space. Each command string should be terminated by the ASCII control code, New

Line (NL), (OAh) or the end of line (EOL) message for GPIB. All commands that end with a question mark (?) are query commands and

required an IEEE-488 read command to retrieve the data from the device's

output buffer.

7.4.2. Test Execution Commands

The following commands are used to control actual output voltage and current from the instrument. Please observe all safety precautions.

Also, like the individual parameter editing commands, the unit should not be included with the value. Only the numeric value should be included in the command string. The list of parameters can also be found in the default parameters section of the manual, or refer to the Test Parameter Editing commands section for the proper values.

The parameter values should use complete text and not use the coded values that are

associated with the individual parameter setting commands such as "ON" and "OFF”.

The LS? companion command will also list all parameters in complete text in the order as they appear in the following table, preceded by the memory number.

7.4.4. Test Parameter Editing Commands and Companion Queries

These commands are used to modify the test parameter within each memory. These commands require a parameter value to be included with the command. The companion query command will read the parameter. The writing of the parameter requires that the unit not be included with the value, only the numeric value should be included with the command. Also, when the query commands are used the response will not include the unit’s characters. Many of the commands will function the same way for multiple test types; however, the input range may be different and therefore used a different possible set of values.

TD?

Read the active data being displayed on the LCD display while the test is in process. It will also read the last data taken when the test sequence has completed. Each parameter is separated by commas and includes memory number, test type, test status, and metering. The syntax for this command response is {memory, test type, status, kV meter, mA meter, dwell time}. Each meter will contain only the value and not the units. In the case of DCW current where both uA and mA are used on the display, the command response will always indicate the current in uA for example

2.0mA will respond with 2000 for 2000uA.

RD <memory number>?

Read the results for an individual memory. The memory number is the actual memory number that has been saved within the file, not the order of which the memories were executed. For example if the test was executed starting from memory 3 and ending with memory 5 then the first test results will be found in location 3 not in location 1. Each parameter is separated by commas and includes memory number, test type, test status, and metering. The syntax for this command response is {memory, test type, status, kV meter, mA meter, dwell time}. Each meter will contain only the value and not the units. In the case of DCW current where both uA and mA are used on the display the command response will always indicate the current in uA for example

2.0mA will respond with 2000 for 2000uA.

RR?

Read the remote Reset input signal. When the remote reset has be activated by closing the contacts the query will return a value of 1 to indicate the instrument is being Reset.

RI?

Read the remote Interlock input signal. When the remote Interlock has be activated by opening the contacts the query will return a value of 0 to indicate the instrument is in the Interlock state and will not be able to generate output voltage or current.

LS?

Lists all the Parameters for the individual memory that is currently selected. See the ADD command for the list of parameters. A comma (,) will separate each parameter and will be preceded with the memory number.

LS <memory number>?

Lists all the Parameters for the individual memory indicated by memory number = 1-

*PSC {1|0}

Sets the power-on status clear bit. When set to 1 the Standard Event Enable register and Status Byte Enable registers will be cleared when power is turned ON. 0 setting indicates the Enable registers will be loaded with Enable register masks from nonvolatile memory at power ON.

*PSC?

Queries the power-on status clear setting. Returns 0 or 1.

*ESR?

*SRE <value>

Service Request enable register controls which bits from the Status Byte should be use to generate a service request when the bit value = 1.

*SRE?

Queries the Service Request enable register. Returns the decimal value of binaryweighted sum of bits.

7.4.8. Status Reporting

Status reporting system is configured using two types of registers. An Event Register and a Summary register. The summary register is known as the Status Byte register and records high-level summary information acquired by the event registers.

An Event register reports defined conditions or messages at each bit. The bits are latched and remain at an active state until the register is either Read or Cleared. Reading the event register automatically clears the register and sets all bits to inactive state or 0. When querying an event register the information is returned as a decimal number representing the binary-weighted sum of all bits within the register.

____________________________________________________________________________

The Enable registers bits represent the selection of bits that will be logically-ORed together to form the summary bit in the status byte. The *CLS command will not clear the enable registers and if you wish to clear the register you must set it to a value of 0. Like the event register, the enable register is represented as a decimal number that equals the binary-weighted sum of all bits.

The enable register will clear to value of 0 at power up unless the *PSC 0 command had been executed before power-off. The *PSC command tells the device whether or not it should clear the enable registers at power-on. Using this command will allow SRQs to function immediately after power-on.

7.4.9. GPIB Service Request

The service request capability is not available with the USB/RS-232 interface. The SRQ line will be activated only after one or more of the service request functions have been enabled using the Status Byte Enable Register command *SRE.

The status byte bit assignments are as described in the previous section for status reporting. When the instrument has requested service, the enabled bit or bits and the RQS bit 6 will be active or 1. Bit 4, 5, and 7 are not used and will be set to false, or 0 for all status byte reads.

After the serial poll (SPOLL) is executed the RQS bit will be cleared to 0, and the remaining bits will remain unchanged. The status byte, ESB bit will not change value until the event register is read and cleared for the corresponding status byte bit.

For example after the All Pass SRQ has been enabled, when the test(s) have finished with pass indications the instrument will set the hardware SRQ line and output the

status byte of 41 hex. This means that bit 6 and bit 0 are set to a value of 1. After reading the status byte the status byte value will change to 01 hex.

7.5. Non Volatile Memory

The instrument saves each parameter in non-volatile memory when the parameters are sent to the instrument. The non-volatile memory has a limited write cycle life, therefore for programmers who wish to send all parameters before executing each test, should use Memory 50. The parameters will be stored in the CPU's Random Access Memory (RAM) until another memory location is selected. However, settings written to RAM from USB/GPIB/RS-232 mode will be lost when power is shut down. Parameter changes to RAM are unlimited and will not affect the life of the internal nonvolatile memory chip.

CODE

DESCRIPTION

GPIB Card

Printer Port (Discontinued)

01 GPIB Card

This option may be substituted for the USB/RS232 interface. This option provides all of the function control of the USB/RS232 interface with the addition of SRQ functions. All commands can be found in section 7.0. Bus Remote Interface USB/RS-232/GPIB of this manual.

02 Printer Port Option (Discontinued)

This option allows the instrument to generate hardcopy printout of the test results. The printout can be configured to print automatically with each test, or manually by pressing a front panel key. There is also capability to enter a serial number identifier to each test that increments automatically after each test is performed. The test can be further configured to print only results from tests that have failed or to print all test results from every test performed.

The Printer Port is a parallel interface and should be compatible with most parallel printers. The printer port output uses simple ASCII characters and control codes. Simply connect the printer to the instrument and configure the printer output using the Setup menu. The following sections describe the setup procedures for configuring the printer output.

Auto Print

Please press the SETUP key to enter the Setup menu. Press the SETUP key six more times to scroll to the Auto Print selection the screen will show:

To configure Autoprinting press the ENTER key to change the selection. When Auto Print = ON the printer output will generate data every time the test has completed, and will also enable two other menus to configure the Print Mode and the Print Number. When Auto Print = OFF the user must press the EXIT/PRINT key on the lower center section of the keypad to generate printer output.

When the EXIT/PRINT key is pressed after the test is completed the printer output will be a duplicate of the front panel LCD test results. This key should only be used to retrieve test results after the test has been completed. Although the output will print the LCD screen during a test, the actual elapsed test time may be effected when printing while the test is active.

Print Mode

Please press the SETUP key. This menu selection works in conjunction with Auto Print. The Print Mode screen appears as follows:

The printer output will generate the 40 character LCD display test results when the test is complete. This selection will determine when the 40-character output will print. When Print Mode = All the printer output will print the test results from every test performed. When Print Mode = Fail only the test that have failed will be printed. The Print Number or Serial number will print for every test, followed by the appropriate test results depending on the Print Mode that has been selected.

____________________________________________________________________________

Print Number

Please press the SETUP key. This menu selection works in conjunction with Auto Print. The Print Number screen appears as follows:

The print number is used to identify each test result. The number can be set to match the exact serial number or some portion of actual serial number of the item under test or just used as an identifier or tracking number. Type in the desired starting number in the range from 0 -9999. This number will increment as each test is performed. The next number that will be used can be viewed from this menu at any time after a test has been completed. This number is not save as part of the non-volatile memory setup parameters. Therefore each time the power to the instrument is turned off, the number will be reset to 0.

Form Feed

Please press the SETUP key. The Form Feed screen appears as follows:

This command forces a form feed after each complete test sequence. When the form feed is turned off the pages will break whenever the page is determined to be full by the printer.

This instrument has been fully calibrated at the factory in accordance to our published specifications and with standards traceable to the National Institute of Standards & Technology (NIST).
