95x Series Operating Manual - June 27, 2016

SECTION 1 – PRODUCT INFORMATION

FEATUR ES

The 95x is an advanced Electrical Safety Analyzer with many standard features which make it unique in this field.
Multiple Capabilities. The 95x is capable of a very wide range of safety tests and is also capable of making
specialty measurements on components – all in the same instrument.
Multiple Safety features. The 95x has many built-in safety features, such as ground current detection,
DUT safety ground disconnection detection, and more. The standard digital interface allows the user to use safety interlocks and remote safety indicators with ease.
No regrets. With all of the features shown here, the 95x is capable of so much more than the typical
users’ present requirements, the user will not regret choosing the 95x when new more stringent
requirements come up in the future.
Wide range of voltages and currents generated. The 95x has a test voltage range from a few 10’s of volts
to several 10’s of kilovolts (for withstand testing) and a test current range from a few microamps to 10’s
of amps (for chassis ground bond testing) at DC or over a frequency range from 20 to 500Hz. The 95x is not limited to just a few voltages, currents or frequencies, the user can specify the actual level and frequency they desire. The 95x is not weak either – loads up to 500VA can be accommodated.
Wide range of voltages and currents measured. The 95x does not just have a wide range of generated
voltages and currents – it can measure them too. From microvolts to 10’s of kilovolts, and from 100’s of picoamps to 100’s of milliamps are all measured by the 95x. Using its’ DSP based technology the 95x knows the difference between breakdown currents, leakage currents and arcing currents and gives you all of the results.
Advanced measurements. When it comes to AC measurements the 95x does not just measure the basics -
the 95x measures total, in phase and quadrature components all of the time and makes available more advanced results such as in phase resistance, quadrature reactance, capacitance and dissipation factors.
Result Analysis. The 95x does not just measure, it analyses the measurements – after a test has been run
the minimum, maximum, average and final measurements are available, a running total of the passes and failures for each test step are also maintained across multiple runs.
Not just “does not breakdown” but “does breakdown” too. The 95x is not only capable of testing that a
DUT does not breakdown, but it is also capable of testing that a surge suppressor type device does breakdown at the correct voltage. Ever worried if that surge suppressor you disconnected while safety testing was correctly reconnected, does it work, is it in specification? Not a problem for the 95x – it can be tested after safety testing.
The 95x adapts itself to the load automatically. The 95x does not have the load restrictions so often found
(and so often hidden in the small print) in other safety analyzers – load capacitances up to a farad during DC withstand testing, highly inductive loads when low resistance testing, and more, are automatically accommodated by the 95x adapting itself to the actual load during each test. Measurements on DUTs like solar panels and computer system line filters are made by the 95x with ease.
Stand alone operation. The 95x can be programmed by the user to perform up to 254 test steps in a
sequence. Each step is automatically performed by the 95x either with or without user intervention as the user desires. Up to 100 such sequences can be defined and maintained in the instrument, no

computer is required. The 95x is capable of controlling switch matrix units (also available from ViTREK) – up to 256 channels can be controlled without needing a computer or software. The 95x can even print a test report on a printer for you when a test sequence has completed.
System operation - Wide range of interfaces available. If the user wishes to use the 95x with a computer,
then RS232, GPIB or Ethernet interfacing can be chosen as the interfacing medium between them. Giving the user the flexibility to use the 95x in almost any computing environment. Software (QuickTest Pro) is available from ViTREK to provide all the control needed for any system from the simple (just the 95x) to the most complex with the 95x terminals being multiplexed between DUTs and/or points within DUTs by up to 1024 channels in switch matrix units (also available from ViTREK).
High Speed. The 95x is capable of performing very quickly, up to 100 tests per second can be performed
with the test results being made available both during each test and after the entire sequence has been run. The 95x is also capable of chaining similar tests without needing to reduce the applied voltage or current to zero between test steps, this considerably speeds up testing when multiple test levels are required.
All of the measurements, all of the time. The 95x does not just measure what the user has set limits for,
all measurement results for the specific type of test being performed are made available to the user.
Energy Efficient. The 95x uses direct line switching power supplies to provide a very energy efficient
instrument, the 95x only draws significant power from the line when needed to power the load.

SECTION 2 – SAFETY

The user should be aware of these safety warnings at all times while using the 95x.
WARNING - THE 95x PRODUCES VOLTAGES AND CURRENTS WHICH MAY BE LETHAL, UNSAFE OPERATION MAY RESULT IN SEVERE INJURY OR DEATH.
WARNING - IF THE 95x IS USED IN A MANNER NOT SPECIFIED BY VITREK, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED AND SAFETY MAY BE COMPROMISED.

POWER AND GROUNDING

WARNING - THE 95x IS INTENDED TO BE POWERED FROM A POWER CORD HAVING A PROTECTIVE
GROUND WIRE WHICH MUST BE INSERTED INTO A POWER OUTLET HAVING A PROTECTIVE GROUND TERMINAL. IF THE 95x IS NOT POWERED FROM A SUITABLE POWER SOURCE THEN THE CHASSIS GROUND TERMINAL LOCATED NEAR THE POWER ENTRY CONNECTOR ON THE REAR PANEL MUST BE PROTECTIVE GROUNDED.
WARNING - TURNING OFF OR OTHERWISE REMOVING POWER TO THE 95x WHILE IT IS GENERATING HIGH VOLTAGES WILL NOT ENABLE THE 95x TO DISCHARGE THE DUT AND MAY DAMAGE THE 95x. THE DUT MAY HAVE DANGEROUS VOLTAGES PRESENT FOR LONG PERIODS OF TIME AFTER THIS OCCURS.
WARNING - DO NOT REMOVE THE POWER CORD FROM THE 95x OR FROM THE SOURCE OF POWER WHILE IT IS OPERATING AT HIGH VOLTAGES. THIS WILL REMOVE THE PROTECTIVE GROUND FROM THE CHASSIS OF THE 95x AND THE DUT WHICH MAY RESULT IN HAZARDOUS VOLTAGES BEING ACCESSIBLE TO THE USER.

TERMINALS AND WIRING

WARNING - THE 95x PRODUCES VOLTAGES AND CURRENTS WHICH MAY BE LETHAL, ENSURE NO
VOLTAGE OR CURRENT IS PRESENT WHEN CONNECTING TO OR DISCONNECTING FROM THE TERMINALS OR DUT.
The HIGH VOLTAGE OR HIGH CURRENT PRESENT warning symbol on the front panel of the 95x is illuminated whenever an unsafe voltage is present on the HV terminal or a high current is present between the SOURCE terminals.
WARNING - THE 95x PRODUCES VOLTAGES OF UP TO 10kVrms ON THE HV TERMINAL(S). THE USER MUST ENSURE THAT CONNECTIONS TO THESE TERMINALS HAVE SUFFICIENT INSULATION FOR THESE VOLTAGES. EVEN WHEN SUFFICIENT INSULATION IS PRESENT, THE USER SHOULD NOT PUT ANY PART OF THEIR BODY IN CLOSE PROXIMITY TO THE CONNECTIONS WHILE HIGH VOLTAGES ARE PRESENT.
The insulation of the wiring to the HV terminal of the 95x must be rated for at least the highest voltage expected during the test sequence.
The user should ensure that all personnel remain at a safe distance from the HV wiring during testing.
Page 15 of 154
95x Series Operating Manual - June 27, 2016
When using high voltages, even if there is sufficient insulation, there may be significant capacitive coupling which can cause an unsafe current to flow to nearby objects and corona can occur even outside of the insulation. This is made worse by sharp corners on objects or the wiring. In severe cases corona can cause interference with the measurements of the 95x and will reduce the capabilities of the wiring insulation over time, eventually resulting in insulation failure.
When using extremely high voltages, especially when using Opt. AC-30, there may be significant mechanical force between the HV wiring and nearby objects. Loose wiring can move several inches, and nearby loose objects (e.g. screws or papers) can be attracted to the high voltage wire.
All terminals of the 95x other than the HV terminal are always protected to be within a safe voltage of the 95x chassis ground, so high voltage wire is generally unnecessary for connections to them.
Should the DUT exhibit significant breakdown or arcing while being tested, there may be very high energy HF interference generated. Although this only lasts for a small period of time before the 95x shuts down, in severe cases this can damage nearby equipment, such as computers. The wiring between the 95x terminals and the DUT should be routed as far as possible away from other equipment and from all cabling connected to other equipment.
When charging high capacitance loads to high DC voltages the capacitor may be unsafe if it or the wiring to it exhibits breakdown while being tested. The energy in the breakdown is generated by the capacitor itself, so there can be no limit on this energy imposed by the 95x.
WARNING - SOME 95x MODELS PRODUCES CURRENTS OF UP TO 40Arms ON THE SOURCE + AND ­TERMINALS. THE USER MUST ENSURE THAT CONNECTIONS TO THESE TERMINALS HAVE A SUFFICIENT CURRENT CARRYING RATING.
The current rating of all wiring must be sufficient for at least the highest current expected from that terminal during the test sequence.
Generally all wiring should be rated for at least 100mA, but the SOURCE+ and SOURCE- terminal wiring for a 952i, 954i or 959i performing Ground Bond testing should be rated for the highest set test current (this may be up to 40A).

USER A CTIV ATED SAFETY ABOR T

The user may depress the STOP button on the 95x front panel at any time while a test sequence is being
run to remove the voltage or current as quickly as possible and abort the test sequence.
The user can configure for a digital INTERLOCK signal to be input to the DIO Interface which will abort a
high voltage or current test step if the interlock is opened. See SECTION 8 – DIO INTERFACE.
The user can configure for a digital ABORT signal to be input to the DIO Interface which will abort any type
of test step if asserted. See
Page 16 of 154
95x Series Operating Manual - June 27, 2016
SECTION 8 – DIO INTERFACE. There are several interface commands which can be used to abort a running test sequence. See SECTION
11 – PROGRAMMING VIA AN INTERFACE.

AUTOMA TIC SAFETY ABORT

For AC or DC voltage test steps, if the breakdown current level is set to <7mApk and the HI SAFETY setting
in the CNFG - TEST menu is enabled, the 95x will fail the test if excessive HV terminal current is detected. This effectively reduces the drive capability of the 95x to a safer level of current (nominally 7.5mA peak) during these test steps. See Test Sequence Configuration.
For AC or DC voltage test steps, the RETURN terminal of the 95x provides a protective ground to the DUT.
The user may wish to take precautions to ensure its’ connection to the DUT. If the CONTINUITY SENSE setting in the CNFG - TEST menu is enabled, and the user connects a separate wire between the SENSE+ terminal of the 95x and the portion of the DUT to which the RETURN terminal wire is connected, then if the RETURN terminal wire becomes disconnected from the DUT the test step will be immediately aborted and the high voltage removed, preventing a potentially unsafe condition. See Test Sequence
Configuration.
If option HSS-2 is not fitted then for AC or DC voltage test steps, if the voltage present on the HV terminal
is detected as being significantly different from that expected during the execution of a test step, then the test sequence is immediately aborted and any high voltage removed, preventing a potentially unsafe condition. This requires no specific configuration by the user.
All processors in the 95x which participate in monitoring the output of the 95x and the condition of the
load check each other nominally every 5ms, if any mis-operation is detected which lasts more than 10ms then the test sequence is immediately aborted and any high voltage removed, preventing a potentially unsafe condition. This requires no specific configuration by the user.
All processors in the 95x have an associated hardware “watchdog” which recovers a mis-operating
processor within typically 100msec. If this occurs during a test then the test sequence is immediately aborted and any high voltage removed, preventing a potentially unsafe condition. This requires no specific configuration by the user.

Measurement Measurement Category I
THE 95x MUST NOT BE USED IN AN ENVIRONMENT WHERE CONDUCTIVE POLLUTION CAN OCCUR, E.G. IN AN OUTDOOR ENVIRONMENT.
IF FLUIDS OR OTHER CONDUCTIVE MATERIALS ARE ALLOWED TO ENTER THE UNIT ENCLOSURE, EVEN IF NOT POWERED, THEN THE UNIT SHOULD BE IMMEDIATELY TAKEN OUT OF OPERATION AND SERVICED AS SAFETY MAY HAVE BEEN COMPROMISED.
IF THE UNIT IS TRANSPORTED BETWEEN DIFFERING ENVIRONMENTS AND CONDENSATION IS SUSPECTED, THE UNIT SHOULD REMAIN UNPOWERED FOR SUFFICIENT TIME FOR CONDENSATION TO HAVE DISSIPATED.

INI TIAL IN SPECTION

After the 95x has been shipped or otherwise handled in an unknown manner, the user should visually inspect the 95x for damage before attempting to operate it. Particular attention should be taken to ensure that there are no significant dents or cracks in any outer surfaces and that all terminals are securely mounted to the unit. If any significant dents or cracks, or any loosely mounted terminals, are noted then it is recommended that the 95x be serviced prior to being placed into use, as safety may have been compromised.

COOLIN G

The 95x is cooled by means of a rear panel mounted fan and cooling vents in the top cover. Sufficient free air must be allowed behind the rear panel and above the top cover to allow sufficient airflow for cooling purposes. At least 2” of well ventilated unrestricted space is recommended around the fan intake and above the vents.
The cooling fan has variable speed to save energy while the 95x is not in use or is not heavily loaded. The user may notice that the fan activates shortly after initial application of line power. This is normal; the fan should stop or
Page 18 of 154
95x Series Operating Manual - June 27, 2016
slow to low speed within 1 minute of application of power. If the fan maintains high speed operation for a long time then the airflow may be overly restricted, or the fan filter may be blocked, the user should take corrective action.
The cooling fan has a removable filter. This is easily removed for cleaning or replacement without disassembling the 95x, see SECTION 9 – PERIODIC MAINTENANCE
The 95x is fully specified for operation in ambient temperatures between 0 and 50C, however best accuracy and full loading capability is obtained if the ambient temperature is maintained below 30C. For best results the user may wish to operate the 95x in a conditioned environment.

MO UNTI NG P OSIT ION AND ORIE NTATION

The 95x may be installed as either a bench top instrument or installed into a standard 19” rack.
The 95x is primarily intended to be used in a horizontal, or close to horizontal position, oriented with the top cover (with the vent holes) uppermost. There are no known issues with mounting the 95x at any angle or orientation, as long as it is mounted in a secure and stable fashion taking into consideration its’ weight and weight distribution.

INSTALLING IN A 19 ” RA CK E NCLOSUR E

Often when installing the 95x into a rack enclosure it is desired to remove the feet from the bottom of the 95x. This is easily achieved by simply removing the screws mounting the feet to the bottom of the unit. The user should place the removed feet and mounting hardware into a bag for safe keeping should they be needed at a later date for bench top usage. DO NOT INSERT THE MOUNTING HARDWARE BACK INTO THE BOTTOM OF THE 95x WITHOUT THE FEET INSTALLED, THIS MAY DAMAGE THE UNIT.
Option RM-1 provides the rack mount ears required for mounting in a standard 19” rack enclosure.
When installing the 95x into a rack enclosure it is recommended that the unit be supported through its’ depth.
The use of a tray or angle brackets supporting the bottom edges of the unit is recommended.

LINE POWER

WARNING - THE 95x IS INTENDED TO BE POWERED FROM A POWER CORD HAVING A PROTECTIVE GROUND WIRE
WHICH MUST BE INSERTED INTO A POWER OUTLET HAVING A PROTECTIVE GROUND TERMINAL. IF THE 95x IS NOT POWERED FROM A SUITABLE POWER SOURCE THEN THE CHASSIS GROUND TERMINAL LOCATED NEAR THE POWER ENTRY CONNECTOR ON THE REAR PANEL MUST BE PROTECTIVE GROUNDED.
The user may connect the 95x to any source of line power within the allowable range of voltages and frequencies (see above) without requiring any adjustment to the 95x.
The 95x line power input is fused with a 5mm x 20mm TT3.15A fuse mounted in the rear panel next to the line power entry. If the user needs to replace this fuse it must be replaced with an exact equivalent fuse, noting the time and current ratings. Although the 95x is fused at 3.15Arms, the unit can draw surges of up to 10Apk during normal operation and up to 100Apk during initial application of power. The user should ensure that the power cord is rated for at least 5Arms continuous operation.

CONNECTING OPTION AC-30 TO T HE 95X

If the 95x has option AC-30 installed, the user must connect the external transformer unit to the 95x in order to be able to use it.
Page 19 of 154
95x Series Operating Manual - June 27, 2016
The user may use the 95x without the external transformer unit if the capabilities of option AC-30 are neither programmed nor required.
CAUTION – ENSURE THAT ALL CONNECTIONS ARE PROPERLY MADE BETWEEN THE OPTION AC-30 EXTERNAL TRANSFORMER UNIT AND THE 95x BEFORE ATTEMPTING TO PERFORM ANY TEST USING OPTION AC-30. EXTREMELY HIGH VOLTAGES CAN BE PRESENT WITHOUT WARNING IF MIS-WIRED.
There are two cables from the option AC-30 external transformer unit which must be correctly connected to the 95x before attempting to perform any test using option AC-30.
A shielded coaxial cable terminated in a BNC connector. This must be connected to the BNC connector
marked EXT FB on the rear panel of the 95x. Ensure this connector is securely fastened to the rear panel connector on the 95x, if this should become disconnected while performing a test, extremely high voltages can exist on the output of the external transformer unit.
A power line cord type cable terminated in three separate connections –
o A spade lug. This must be securely connected to the Ground terminal located above the power
connector on the rear panel of the 95x.
o A pair of shrouded banana plugs. These must be connected to the safety banana sockets marked
EXT DRIVE on the rear panel of the 95x. There is no polarity requirement regarding these connections.

95x Series Operating Manual - June 27, 2016

SECTION 4 – GENERAL FRONT PANEL OPERATION

This section gives general information regarding using the front panel and its’ menus.

FRONT PANE L

1. The display. This shows all menus during interactive data entries, all measurements during a test, and the
present date/time when not performing any other duties.
2. The POWER switch. This turns on/off the power to the 95x.
3. The START and STOP buttons. a. The START button allows the user to start performing a previous selected test sequence, or
(while running a test sequence) select to continue a test step when it is waiting for the user to do so.
b. The STOP button aborts any test sequence in progress (while running a test sequence), aborts
the menu activity in progress discarding any changes made (while performing a menu), or makes no test sequence selected (otherwise).
4. The menu selection keys. During all menus, the selected element of the menu is highlighted by flashing
between the data and blocks. These keys allow the user to move the selection point within a menu.
a. The Left and Right Arrow keys are used to move the selection point within a menu. b. The ENTER key is used to finish entry of a menu data and automatically move to the next menu
item.
c. The EXIT key (labeled EXIT/SAVE on later units) is used to save all changes made within a menu
and return to the previous menu (if any) or to the inactive display.
5. The edit keys. These allow the user to decrement or increment a selected menu items’ value. During
numeric entry these initiate “edit” mode of data entry, rather than “direct” mode of data entry (i.e. allow the user to adjust the existing entry using the Up/Down Arrow keys, rather than overwriting the existing value with a new value using the numeric keys). For convenience, these keys auto-repeat if the user maintains pressure on them.
6. The indicators. a. HIGH VOLTAGE OR HIGH CURRENT PRESENT. This is illuminated whenever the 95x has a high
voltage (>30V) or a high current (>5A) present on its’ terminals.
Page 21 of 154
95x Series Operating Manual - June 27, 2016
b. PASS. This is illuminated whenever a test sequence is passing (while running a test sequence) or
it has passed all test steps (following completion of the test sequence).
c. FAIL. This is illuminated whenever a test sequence is failing (while running a test sequence) or
the previously run test sequence has failed any test steps (following completion of the test sequence).
d. TESTING. This is illuminated when the 95x is running a test sequence. e. READY. This is illuminated after the user has selected a test sequence to run and the 95x is ready
to perform that test sequence.
f. ARC. This is illuminated whenever the 95x is detecting an arc current while running a test
sequence and the specific test step is enabled to detect arc current.
g. C/V LIMITED. This is illuminated when the 95x output is either current or voltage limited by the
load while running a test sequence. This is only used in certain types of test steps.
h. REMOTE. This is illuminated when the 95x is under the control of an interface (i.e. RS232,
Ethernet or GPIB). If the user wishes to return to front panel control of the 95x the CNFG key should be pressed to achieve this.
7. The menu keys. These initiate a menu allowing the user to perform certain activities via the front panel of
the 95x. Many of these can be disabled by the user by requiring a password in order to utilize them.
a. SELECT. Initiates a menu allowing the user to select a test sequence which has already been
defined in the 95x. This never requires a password.
b. EDIT. Initiates a menu allowing the user to select an existing test sequence and then edit it.
After editing it is automatically made ready to run. This optionally requires a password.
c. NEW. Initiates a menu allowing the user to select a presently undefined test sequence number
and name, and then to create the sequence of tests to be performed. This optionally requires a password. While editing or creating a test sequence, this key is also used to insert a new test step into the test sequence.
d. DEL. Initiates a menu allowing the user to select an existing test sequence and delete it from the
95x. This optionally requires a password. While editing or creating a test sequence, this key is also used to delete a test step from the test sequence.
e. PRINT. If option UL-2 or GUL-3 is fitted and a suitable printer is attached, this key causes a
printout to be generated. This never requires a password. The printout generated is dependent on the menu (if any) which is active when the key is pressed –
i. If pressed while no menu is active, or the configuration menu is active, a configuration
printout is generated.
ii. If pressed while selecting an existing test sequence, a test sequence printout is
generated.
iii. If pressed while reviewing the results of a completed test sequence, a test results report
printout is generated. The 95x can also be configured to automatically produce this printout if desired.
f. VIEW. Initiates a menu allowing the user to either –
Page 22 of 154
95x Series Operating Manual - June 27, 2016
i. If no test sequence is ready to run. View the pass and fail counts for any defined test
sequence, and optionally to clear them. This never requires a password except (optionally) to clear the counts.
ii. If a test sequence has been run and is still selected. View the test results of each step
within the previously run test sequence. This is automatically performed after a test sequence has been run. This never requires a password.
g. LEADS. Allows the user to run the presently selected test sequence in Lead Compensation mode.
This allows the 95x to store any load offsets for each step in the test sequence and to correct all future tests using that test sequence for these load offsets. This optionally requires a password.
h. EXT. Allows the user to perform either an adjustment or verification calibration of the 95x
against external standards. This optionally requires a password (this is separate to the other menu activity password).
i. CNFG. Initiates a menu allowing the user to configure the 95x. This uses a series of sub-menus.
This optionally requires a password.
j. TEST. Shows the present operational status of the 95x and allows the user to perform internal
operation verification (this optionally requires a password).
8. The data entry keys. a. The numeric keys (0 through 9), decimal point and change sign keys. These are used during
numeric or character data entry. NOTE – during hexadecimal or character data entry, certain of the menu keys can be used for entry of the A through F characters.
b. The UNIT key. This is used to change the units during numeric data entry, and is also used while
running a test, or while reviewing test results, to change the displayed test result measurement.
c. The LIMIT key. This is used during numeric data entry to set a value to the largest possible.
When setting test dwell times this sets that the dwell should be user terminated rather than automatically terminated after the entered time. When setting a resistance type upper limit, this allows the user to set that there is no upper limit.
d. CLEAR key. This is used to clear an entry during numeric or character data entry.

ME NU O PERATION AND DAT A ENTRY

Most user activities using the front panel controls are performed using menus. All menus use the same general operating methods described in this section. The user should read this section before attempting to operate the 95x.

BAS E ME N U S T ATE

When the 95x is not performing a menu and is not performing a test sequence, the display shows the model # in the uppermost display line and the date and time in the lower most display line, this is called the base menu state in this document. Most menus require the 95x to be in the base menu state to be initiated, an example of the base menu state display is -
ViTREK 951i 9-Feb-10 9:08:51am
If the 95x is not in this state and the user is unsure how to return to this state, then pressing the STOP button will accomplish this (in some circumstances the STOP button may need to be pressed more than once).
Page 23 of 154
95x Series Operating Manual - June 27, 2016

NAV IGAT ING M ENUS

The present selection point in a menu is denoted by the displayed information flashing between the
information and solid blocks.
The user can move the selection point in a menu by using the Left and/or Right Arrow keys.
o The Right Arrow key moves the selection point further down the menu. Moving the selection
point past the last selectable item in a menu selects the first selectable item in the menu (a double beep sound is made when this occurs).
o The Left Arrow key moves the selection point further up the menu. Moving the selection point
before the first selectable item in a menu selects the last selectable item in the menu (a double beep sound is made when this occurs).
Although the 95x display is limited to two lines, most menus have more lines than this. The display is
automatically scrolled up and down the menu to display the menu line containing the present selection point.
Not all menus or menu lines may be available.
o Generally items which are not pertinent to the specific model or option content of the 95x are
not shown.
o All menus in the 95x utilize a “top down” priority. Selections or entries made may affect
subsequent entries in the menu. Entries may be limited in allowable values, or may not be shown.
If a menu line is an entry into a sub-menu, then the left side of the line shows descriptive text followed by
an ellipsis character (…). The descriptive text is selectable. If the user presses the ENTER key while a sub- menu entry line is selected then the sub-menu is opened.
o When a sub-menu is terminated by pressing the EXIT key then the user is returned to the
preceding level of menu.
o If any level of sub-menu is terminated using the STOP button then all levels of menus are aborted
and any changes made at any level are discarded.
o Only when the base level menu is terminated by pressing the EXIT key are any changes made
actually saved.
If a menu line is for informative purposes only, then the left side of the line shows descriptive text
followed by a colon character with the informative data at the right end of the line. The descriptive text is selectable.
If a menu line allows the user to edit its’ contents, then the left side of the line shows descriptive text
followed by a colon character with the editable data at the right end of the line. The editable data is selectable; some menu lines may contain more than one editable data.

MOD IFYI N G ME NU E NTRI ES

In many places the available contents of entries in different menu lines are inter-related. The 95x uses a
“top down” menu approach; the topmost contents in a menu may limit the available entries in the menu below them, but not vice versa. Generally the user cannot set a limit or an output which the specific model and option content of the 95x is not capable of achieving.
Page 24 of 154
95x Series Operating Manual - June 27, 2016
Changing Numeric Data. After making the numeric data the selection point in the menu, the user can
overwrite the data by using the data entry keys. While overwriting, the selection point becomes a single character position within the numeric data.
o A numeric key places the corresponding character and moves the selection point to the right one
position.
o Certain numeric data allow the user to change the units of the data (e.g. between current and
resistance) and/or change the multiplier for the data (e.g. select an entry in microamps or milliamps). To change the units, press the UNIT key while the entire numeric data is selected; to change the multiplier, press the UNIT key while entering the numeric data.
o The Left Arrow key acts as a delete key, deleting the previously entered character. o The CLR key removes all of the existing entry and places the selection point in the rightmost
character position.
o The LIMIT key sets the numeric data to the highest possible value in most cases; while entering
the lower limit in a range pair of data the LIMIT key sets the minimum value; in some other cases the LIMIT key has a special use denoted in the description for that specific data.
o The Right Arrow or ENTER key terminates the numerical data entry and also moves the selection
point to the right or downwards, as applicable.
Changing Multiple Choice Data. After making the multiple choice data the selection point in the menu,
the user can change the selection by repeatedly pressing the Up Arrow or Down Arrow keys until the desired selection is displayed. The ENTER key terminates the multiple choice data entry and also moves the selection point to the right or downwards, as applicable. The Left Arrow and Right Arrow keys automatically terminate the multiple choice data entry prior to moving the selection point accordingly.
Changing Character Data. After making the character data the selection point in the menu, the user can
choose to either edit the existing data, or to overwrite it with new data. While overwriting or editing the data the selection point becomes a single character position within the character data.
o Editing Existing Character Data. If the user presses the Up Arrow or Down Arrow key while the
entire character data is selected then the edit mode of entry is initiated and the leftmost character of the existing data is selected. Character data uses a limited character set; A through Z, a through z, 0 through 9, the space character and most punctuation characters.
The Up Arrow and Down Arrow keys change the selected character to the next or
previous available character in the character set.
The numeric keys and the A through F keys overwrite the selected character. The Left Arrow and Right Arrow keys move the selection point within the character data
area.
The CLR key aborts the edit, the character data is cleared, and the overwrite mode is
initiated.
The ENTER key exits the edit mode retaining the changes made.
o Overwriting Character Data. If the user presses any of the numeric keys or the CLR key then the
overwrite mode of entry is initiated, starting with the corresponding character and with the leftmost character.
Page 25 of 154
95x Series Operating Manual - June 27, 2016
The Up Arrow and Down Arrow keys change the selected character to the next or
previous available character in the character set.
The numeric keys and the A through F keys places the corresponding character and
moves the selection point to the right one position.
The Left Arrow key acts as a delete key, deleting the previous character and moving the
selection point to the left one position.
The Right Arrow key places a space character and moves the selection point to the right
one position.
The CLR key removes all of the existing entry and places the selection point in the
leftmost character position.
The ENTER key terminates the character data entry retaining the changes made and also
moves the selection point in the menu to the right or downwards, as applicable.
Changing Hexadecimal Data. Hexadecimal data is treated exactly the same as character data (see above)
but with the available character set restricted to 0 through 9 and A through F.

ADJUST ING THE DISPLAY CONT RAST

The user can adjust the display contrast while the 95x is in the base menu state (i.e. the display shows the model number and the time/date). An example display when the user can adjust the display contrast is –
ViTREK 951i 9-Feb-10 9:08:51am
Using the Up and Down Arrows keys, select the display contrast which best suits the users normal viewing position.
NOTE – it may be possible to adjust the display contrast such that the display is not visible. If the display appears to be totally blank then press and hold the Down Arrow key to return it to the visible state; if the display appears to have all of its dots “black” then press and hold the Up Arrow key to return it to the visible state.
NOTE – it may be best to select the contrast which shows the least “blurring” when the seconds digit in the displayed time changes. This has been found to produce the best adjustment for viewing angle as well as contrast.

LOCKIN G AN D UN LOCKING MENU S

Many menus in the 95x can be locked by a user, preventing unauthorized changes to test sequences and configuration settings via the front panel of the 95x. When initially delivered from the factory, this capability is disabled.
The password is any combination of six 0 through 9 and A through F characters. The password 000000 indicates a cleared password, disabling this capability until a non-zero password is subsequently set by the user.
If a menu lock password has been set, the 95x always powers up with the menus locked.

UNL OCKI N G M ENUS

If the menu lock password has been set, a user must enter this password to unlock a menu. The user is prompted to enter the password when needed; which is accomplished by using the 0 through 9 and A through F keys as needed to match the previously set password, followed by the ENTER key. After successfully entering the password the front panel menus remains unlocked until the menus are relocked by the user or the 95x is power cycled. Note that the 95x display does not show the characters during unlock password entry for security reasons.
