METROLOGY

The meteorological conditions of your measurement instrument are defined in the specifications of this notice. Climate and environmental conditions restrict the specifications of your recorder. SEFRAM checks the characteristics of each appliance one by one on an automatic bench during its manufacture. The adjustment and control are guaranteed under conditions of the ISO9001 certification by facilities in connection with the COFRAC (or equivalent in the context of ILAC reciprocity). The specified characteristics are considered stable for a period of 12 months from the first use under normal conditions of use. We recommend a check after 12 months and max. 24 months of use, then every 12 months after 24 months. For any check of the characteristics, the following average climate conditions shall be maintained (23°C+3°C – 50(+20)%RH). The recorder should have been working for 0,5 hour before check.

We recommend that you have this control made by our after-sales service (Service Après-Vente) for the best service and preservation of the measuring quality of your instrument. When a recorder returns to SEFRAM, maximum service is provided with internal updating according to the required adjustments and software updates. In case of shift in the characteristics, your instrument shall be adjusted to recover its original characteristics.

Page 3.5

Setup and precautions of use

3.4.3. Temperature measurement with a thermocouple

Isolated input module: The voltage produced by the thermocouple effect must be measured between the red and black poles of the concerned input. To guarantee a right measurement, connect directly both ends of the thermocouple cord on banana plugs. Plug these two banana plugs onto the input you want with respect for the polarity.

Do not use male banana plugs for welding: the soldered joint would alter the thermocouple effect.

Non-isolated differential input module and Isolated strain gauge input module: The voltage produced by the thermocouple effect must be measured between the « + » and « - » poles of the inputs with wires on the screw terminal. To guarantee the right measurement, plug directly both ends of the thermocouple cord on to the input you want with respect for the polarity.

Page 3.8

Setup and precautions of use

3.4.6. Intensity measurement

Isolated input module: it is possible to make intensity measurements with a shunt between the red and black poles of the treated input.

Non-isolated differential input module: it is possible to make intensity measurements with a shunt between the « + » and « - » poles of the treated

input.

In this case, select the "current" type in the parameters of the selected channel. Connect the measurement wires to the poles of the shunt. The results are displayed directly in A or mA according to the caliber of the selected channel.

3.4.7. Earth

For measuring very low voltage values, the problem of the parasite voltages induced by electromagnetic fields or ordinary mode voltages are all the more important than the selected sensitivity is high. Hence, it is important that the outer cables are correctly settled.

There are various causes to such difficulties:

- uncertainty about the true origin of the disturbing voltages and impedances

- uncertainty about the parasite capacities of the circuits and cables

- no access to the point of injection of the ordinary mode voltage from the circuit providing the signal to record

- non-conformity of some appliances to the valid norms

- Sometimes, ignorance of the source impedances of the signals to record.

T IS ADVISABLE TO RESPECT THE FOLLOWING PRESCRIPTIONS

Page 3.9

Setup and precautions of use

1/ the mechanical groundings of every appliance must be earthed. The mechanical grounding of the recorder is connected to the earth through the cord of the mains or thanks to the protective wire. However, if the other appliances of the mounting do not include this possibility, it is advisable to gather their mechanical groundings with the one of the recorder, since it is available on a bush at the rear of the appliance.

2/ If the source of the signal to record has a low internal impedance, you will use twisted wires. If the source of the signal to record has high internal impedance, you will use shielded wires.

3/ When gathering the groundings of the various items of the measurement chain, you’d better check that there is no differential ground potentials between them in order to prevent any short-circuit. In case of doubt, use a voltmeter to measure it after placing a weak charge (i.e. 1 kΩ) between the poles.

3.5. Routine maintenance

The maintenance is not restricted to cleaning the outside of the appliance. Any other operation requires some qualified personal.

Unplug the appliance before any intervention.

Do not leave water flow into the appliance, to prevent any risk of electric shock. Regularly clean the recorder in respect with the following instructions:

- use water and soap to cleanse the front and rear plates

- never use any product made of essence, benzene or alcohol that would attack the silk-screenings

- wipe with a soft lint-free cloth

- use an antistatic product to cleanse the screen

Ex. In RMS mode, it is interesting to have the zero at the minimum value (-100%): the maximum value will be equal to the caliber.

The lower zone of the LCD screen shows the min. and max. values (limits) possible for the measure values and the zero position. A warning message shows up on the right when the analogical thresholds are out of measurable range.

 Rule 1 : Every instructions or calculation must end with a semi-colon ;

 Rule 2 : Channels name must be written between simple quotes like (the number of spaces must also be respected) ‘Channel A1’  Rule 3 : Each variable must be declared only once with the keyword var. Example: var MyVariable=3;  Rule 4: The result is stored in the current function channel by using the keyword function. Example : function=2;

Scripts syntax

Mathematical scripts ‘syntax is inherited from the programming language C. Programming scripts is a rigorous exercise which imply to respect some elementary rules to avoid error messages.

The three fundamental rules are:

By respecting these four rules, a basic script adding the Channel A1, Channel A2 and Channel A3 will look like:

Use

Page 4.12

Rule 3: Variable a is declared

Rule 3: Variable b is declared

Addition of a and b, the current function being FA the result is store in FA. The keyword var is no more used to refer to the already declared variable.

Rule 1: The semi-colons end the

different calculation.

Variable names must only contain alphanumeric character and at the opposition of channels’ names they must not be written between simple quotes.

For long scripts it will be better to use intermediate variables to ease the maintenance or the future modifications. As mentioned in the rule 3, each variable must be declared before its use:

In addition to the linear mathematical operators as +, -, x, /, it is possible to use non linear mathematical function with variables and channels. The list of these functions can be found in the menu Function in the editor’s toolbar. A function is used by writing its name followed by a list of parameters between parentheses separated with comas.

Example: The channel rise to the 3th power:

5. TRIGGERS

This chapter describes all triggers available in this appliance.

You can use them with:

 « Setup » key, parameters « Alarm A, B and C »  « Trigger » key, parameters « Start » and « Stop »

 Edge / level trigger

 on an edge: you need a change of state

Example: channel A1, positive edge, threshold = 0 V: trigger when the signal turns from negative state to positive state.  on a level: you don’t need to pass a threshold Example: channel A1, high level, threshold = 0 V: trigger if the signal is positive

Alarms only have level triggers.

 Analog / Logical channels: trigger according to analogical or logic channels  Analog channel (only one threshold) / Combination Analog channel (several thresholds):

 triggering from only one channel and one threshold  or complex triggering from several channels and several thresholds; see description below.

Such complex triggering is only possible with analogical channels.

Triggerings

Page 5.1

 Channel: selection of the channel on which the

triggering threshold is applied

 Threshold 1 / Threshold 2: selection of the

threshold to set up; each channel is tested against 2 thresholds. For example, you can program an initial condition on the channel A1 and the threshold 1, and a stop condition on the same channel A1 and the threshold 2.

 Level/Edge:

- Level: Select of the level, either > superior,

or < negative.

- Front: Selection of the active front of the

channel against the threshold. For example: the condition A1 (s1)↑ 0.500A becomes TRUE when the channel A1 becomes higher than 0.5 A.

 Filter :

When the level is selected , a filter can be added ( from 1µs to 10s) .

5.1. Trigger with Combination Analog channel

After selection of the triggering on analogical channels, the following line on screen allows you to set up the triggering condition. It depends on the selection between only one or several thresholds.

5.1.1. Analog channel (only one threshold)

Triggerings

Page 5.2

 One threshold (OR): the first achieved condition validates

the trigger

 All thresholds (AND): all conditions must be simultaneously

achieved to validate the trigger

 Slope (OR): trigger according to the slope of signals; the

first achieved condition validates the trigger

 Channel: selection of the channel of the triggering threshold  Threshold 1 / Threshold 2: selection of the threshold to set

up; each channel is tested against 2 thresholds. For example, you can test an initial condition on the channel A1 and the Threshold 1, and a stop condition on the same channel A1 and the Threshold 2.

 Level / Edge:

Level: Selection of the level, either > superior, or < negative. Edge: Selection of the active edge of the channel against the threshold. For example, the condition A1 (s1) ↑ 0.500A becomes TRUE when the channel A1 becomes higher than

0.5 A.

5.1.2. Combination Analog channel (several thresholds)

After selection of a trigger according to Combination Analog channel, there are several ways to set up the complex triggering condition:



Filter :

When the level is selected , a filter can be added ( from 1µs to 10s) .

 Add: Allows you to add an additional channel. To suppress a channel, press its value (for example 0.00 V) in the table on the left and select

« Erase ».

Triggerings

Page 5.3

5.1.3. Threshold triggering

Triggerings

Example: the trigger here above is Trigger if

Channel A1 increasing and equal to the threshold S1 with value 0.500 A OR Channel A2 increasing and equal to the threshold S1 with value 0.500 V OR Channel A2 increasing and equal to the threshold S2 with value 0.500 V OR Channel A3 decreasing and equal to the threshold S1 with value 0.500 V

The same analysis is valid for the trigger AND (all thresholds).

Page 5.4

5.1.4. Parasites:

You can trigger a parasite with a periodic 50Hz signal: trigger when the shape of the signal radically changes:

 parasite impulsion >200μs  sudden change of frequency  sudden change of shape

channels:

 One channel  Triphase (only channel A1,A2 and A3 )

Sensibility : percent of the fullsccale.

Triggerings

Example: the trigger here above is

Trigger if

Channel A1 increasing with a positive slope of 0.500 V over a 1s period OR

Channel A2 increasing with a positive slope of 0.500 V over a 1s period

This triggering mode is not used with alarms.

- Amplitude: min. value, max value, peak to peak, low, high, amplitude, on oscillations

- Time: frequency, period, increase time, decrease time, positive width, negative width, positive and negative cyclic ratio

- Calculation: average, cyclic average, RMS and cyclic RMS

Up to 6 calculations can be displayed on screen simultaneously.

The values are displayed in rectangles above the diagrams where appear:

- the number of the channel (with the corresponding color)

- the type of calculation

- the value of calculation

The calculations are made in real time; their result is updated every 300 ms. The calculation is made on the 1000 dots displayed on screen. Hence, the time resolution is 0.1%.

Page 6.1

Calculations can be made on every channel. However, you cannot made calculations:

- On addition channels functions of other channels (Example F3=A1+B2)

MEMORY mode

8.2. Sampling period

When input signals frequency is too high, it is necessary save the measured signals with a high acquisition speed: it is the Memory mode. The sampling consists in taking the instantaneous value of a signal with regular intervals, each of these values is saved in the memory.

For a satisfactory periodic signal, you must select a sampling period compatible with the signals frequency on the input terminals of the recorder.

A 10 points definition per signal period is a minimum for getting a satisfactory drawing.

8.3. Internal memory _ blocks

The memory available on the recorder can be separated in blocks which are filled successively during each acquisition.

The acquisition depth is N/(B*V) N= total memory B= number of block V= number of channel to get

Example: 128 Msamples memory, 32 blocks and 4 ‘ON’channels, so N= 128,000,000/(16*3)=1,000,000 samples/channels

Every new acquisition is placed automatically in the first free block (in ascending direction). When all acquisitions are busy, a new one causes the gap of previous blocks in the N-1 block; the first block will be lost.

The new acquisition, as a result, will take the place of the last block.

Page 8.3

MEMORY mode

8.4. Trigger position

The acquisition in a memory block is based on the principle of “cine memory”:

 the memory is filled from the starting condition  the memory is filled as long as the stopping condition is not valid; if the memory is full, the filling starts at the beginning of the memory

zone (block)

The memory block always has the N last samples.

User can select the moment when the present samples in memory will be freeze; to do this, he has to define a period which separates the trigger moment of the beginning of the effective back-up.

This period can be positive or negative, so the memorized samples can be before, after, or on both sides of the trigger moment.

You can also not inhibit the trigger: it allows you to test the trigger during the pre triggering phase in case of the trigger arrives before the end of this phase. In case of repetitive signals, the trigger is inhibited.

Back up with a period of -50% Back up with a period of +50% In relation with the beginning of the memory In relation with the beginning of the memory

8.5. Double Trigger Mode

In this mode, a starting trigger and a stopping trigger are used.

You will record measures between these two triggers.

Page 8.4

The acquisition will stop automatically:

 when the stopping condition is valid  when the memory block is full

An information window sums the general setup of the acquisition:

 channels and functions between validated channels for the acquisition

 number of points per channels (function of the number of blocks)  acquisition total time (function of acquisition speed)  trigger position (function of pre triggering)

8.6. Recording

The acquisition launch is performed by pressing the “recording” key.

The following information appears on the top and on the left of the screen:

 the number of block in progress if there is some  the current sampling speed  The acquisition condition (waiting of the trigger, filling xx %...)  the opening of a file of back up, if there is some

If the acquisition time is below 2 minutes, the total acquisition is visualized. In that case, you cannot exit from this page: the acquisition must stop to change of menu.

For long acquisition times, you can zoom on a part of the data or change of page. When you change the menu page, you can return to acquisition by pressing the “recording” button.

- Waiting: after a period or a precise date and hour

- Automatic: immediate; automatic stop when the block is full

Pre triggering: definition of the position of the starting trigger in the acquisition

 Acquisition pre triggering and post triggering (before or after the start), see chapter Memory Mode

Caliber channels: selection of the channels to compare with the caliber (by pressing on “caliber channels”; access to the definition of the caliber)

“Impossible” is displayed when the possibilities of back up are not possible anymore: reduce the sampling speed or the number of channels

See chapter File Mode to know the limits of the recording on a file.

Rest of acquisition: actions after the end of the acquisition

 Back up in a file: back up the acquisition in a file if the Real Time back up is not validated (or is impossible)  Sending an email: this option will appear if you added a mail address before in “additional options” in the Setup. Menu;  Drawing: drawing of the simultaneous acquisition in memory  Stop: no action  Rearmament: launch the drawing again; waiting for the starting condition again  Change setup: loading of a configuration and waiting of the triggering

9.2. Creation of the caliber

Set the parameter “caliber channels” in the page “triggering” selecting a channel and a logical operator (AND or OR)

Do a normal acquisition or observe a file previously saved by the “memory output” function.

The appliance displays the current caliber, shown with 2 curves (one min, and one max) around the selected channel as reference for the caliber.

 Start and End: limit of the memory depth where the

stopping triggering test will be performed

 Save : when the caliber is correct, you can save it in

the non volatile internal memory

 Return : return to the previous page, the caliber is no

changed

The 2 curves are saved in an internal file.

FILE Mode

9.3. Use of the caliber

The comparison with the caliber is used to stop the acquisition. This comparison will be performed on the “caliber channels” selected in the page “triggering”.

The information window at the bottom of the page “triggering” sums the general setup of acquisition:

 Channels and functions validated for the acquisition  Channels and functions compared with the caliber  The number of points per channels (function of the number of blocks)  The total time of acquisition (function of acquisition speed)  The position of the trigger (function of pre triggering)

Page 9.3

FILE Mode

The acquisition is performed as previously (see chapter Memory mode).

When the memory block is full, the appliance checks that all points got on caliber channels are situated between the 2 min and max curves of reference that constitute the caliber.

If all points are inside the curves, the acquisition starts again (in the same block). Otherwise, the acquisition is stopped.

the folder FolderGraticule

Page 10.10

10.4. Limitation

The real time data acquisition onto a file is limited by the transfer rate between the inputs and by the hard drive write speed.

The maximum transfer rate onto a hard drive is 6 Msample/s.

To know the number of channels that you can record at a given acquisition period, follow the following formula:

*number of channels = 6 000 000 x acquisition period

Example: acquisition period: 10 µs Number of channels = 6 000 000 x 10 µs = max. 60 channels

« Impossible » shows up when all possibilities of back-up are exceeded: reduce the sample rate or the number of channels

After the record it’s possible to create a text file ( choose the format in the page Setup) ( save file) On a PC it’s possible to download the binary file with FTP and convert this file directly in text, csv or excel file with seframpilot

Example: the command “c:/program/seframviewer myfile.rec /t” convert directly myfile.rec in myfime.txt
