BASIC OPERATION
Section 2
POWER-UP
Upon switching on the power to the unit, the display shows the following information for approximately 4 seconds.
After the power-up display information, the instrument starts showing the process value(s) for Single / Dual Channels. This is
the MAIN Display Mode that shall be used most often.
MAIN DISPLAY MODE
This is the default display mode. This mode actually comprises of 4 different screens providing different information. The 4
screens are described below. Use Enter key (press and release) to switch from one screen to the next. The last screen rolls
back to the first screen. The multiple information within a selected screen can be viewed using UP / DOWN keys.
Process Value Screen
This is the default screen upon entering the Main Display Mode. The Upper Row shows the Channel Name and the Lower Row
shows the corresponding Process Value along with user set Units as shown below.

In case of Dual Channel, the channel-wise process value indication update depends upon the selected Auto / Manual scan
mode. The scan mode can be toggled between Auto and Manual by holding the ENTER key pressed for approximately 5
Seconds. The front panel LED indicator glows ON in Auto mode and remains OFF in manual mode. The channel update rate in
Auto mode depends upon the set value (1 to 99 Sec.) for the parameter ‘Scan Rate’. In Manual mode, the channels can only
be scrolled using UP and DOWN keys. However, in Auto Mode though the channels are automatically scrolled with set
interval, the UP/DOWN Keys can still be used for quick manual scrolling through channels.
Alarm Status Information Screen
There are up to 4 soft Alarms (AL1, AL2, AL3 and AL4) provided for each channel. If any one or more set Alarms for a channel
is active, the channel is said to be under Alarm condition. The channel names under Alarm condition keep flashing on the
Upper Row in Process Value screen.
The complete Alarm status information for the channels under Alarm condition is available on this Screen. For example; If
Alarm1 (AL1) and Alarm3 (AL3) of a channel named ‘Boiler Pressure’ is active then the screen displays the following

PEN-DRIVE OPERATIONS
Section 3
The Instrument can perform both, File Read and File Write, operations on the Pen Drive. The File Read Operation facilitates
assigning user defined names to each input channels while the File Write operation allows copying the Process Value records
(stored inside the internal memory of the instrument) onto the Pen Drive for subsequent reading in Excel Sheet. The two file
operations are described in detail in the following pages.
File System for Read Operation
The Instrument continuously monitors and updates the Process Values (PVs) for each channel. The Process Values are
displayed on the front panel Dual Row LCD display. The Upper Row displays the channel name whereas the corresponding
PV and measurement Units are shown on the Lower Row.
Channel Names
The Instrument is shipped from the factory with each channel assigned a factory set default name in accordance to the
numbers assigned to the channels. That is, Channel-1 & Channel-2. The user can, however, assign a more meaningful name
(such as Boiler Pressure, Oil Temperature, etc.), to each channel for easy identification of the process parameters that are
being measured and displayed.
Instrument Name
The Instrument Name is useful in identifying the equipment (like Ageing Oven, Muffle Furnace, Test Chamber, etc.) or the
location (like Paint Room, Test Lab, etc.) where recording is performed. The Instrument Name is mentioned in the File Header
(described later) section of the file where the stored records are copied. The instrument is shipped from the factory with a
default Instrument Name; ScanLog 96. This default instrument name can be changed by the user using the file read facility.
File Name
The instrument (ScanLog) downloads the records by creating a unique default File Name (explained later). The user can
however define a different file name by using file read facility.
For File read operation the user should create and save a text document file with the name Set.txt using Microsoft Notepad
Application tool. The Set.txt file must be saved on the Pen Drive in the main directory (outside of any folders).
Refer Figure 3.1 for example file. Follow the guidelines below for creating and/or editing the file Set.txt.
1. The lines with text within square brackets before user defined names are required.
2. The text within square brackets are case insensitive.
3. No blank lines are permitted. Do not press enter after typing last line.
4. The Channel Names must not exceed 16 characters.
5. The Instrument Name must not exceed 16 characters.
6. The File Name must not exceed 8 characters. Regardless of the letter case (lower or upper) used for the file name set by
the user, the file is always created with upper case letters. For example; for the user set file name NewName, the
instrument creates file NEWNAME.csv.

User Manual
ScanLog 96 Pen Drive Version

Figure 3.1
File System for Write Operation
ScanLog continuously monitors and measures the process values for all channels and compares these values with the user
set Alarm limits to generate Alarm Status.
A set of Process Values along with the corresponding Alarm Status for all channels, stamped with the current Date and Time, is
called a Record. ScanLog stores such records in its internal memory at user set time interval, called Recording Interval. These
stored records are then available for downloading to a Pen Drive via the front panel USB connector.
Each of the installed ScanLog creates and maintains its own Record-Data file on Pen Drive using either user defined File
Name or a file naming scheme that involves a unique 5 Digit Code which is factory set. This 5 Digit Code can be viewed using
the Read-only parameter “UNIQUE ID NUMBER” on the page “RTC Settings”. This Read parameter value is actually an 8 digit
number of which last 5 digits are used for file naming. Under this file naming scheme the file is named RECnnnnn.csv; where
nnnnn is the unique 5 Digit Code just described above. For example; if the “UNIQUE ID NUMBER” is 15030006 then the file is
named REC30006.csv. The records are downloaded to the file on Pen Drive in Comma Separated Values (CSV) format and
thus the file is assigned the extension “.csv ”. Note that once the user supplies his own File Name the ScanLog does not use
the file naming scheme stated above. That is either the user defined File Name or the file name created using unique 5 Digit
Code is stored inside ScanLog’s memory. The stored File Name can be viewed using Enter Key (Refer Section 2 : Basic
Operation).
Upon selecting the ‘Copy (New)’ or ‘Re-copy (Old)’ operation (explained later) after insertion of the Pen Drive; the ScanLog
first searches for any existing file that matches with the file name stored in its memory.
Case 1 : File exists
If the File with the name stored in ScanLog’s memory exists on the pen drive, the ScanLog first reads the File Header that
comprises the Instrument Name & the 8 digit UNIQUE ID NUMBER (Refer Figure 3.2). If the 8 digit UNIQUE ID NUMBER
matches then the ScanLog appends the available stored records to the file, else the message shown in the figure is displayed :

Back-up File System
It is possible that a file-write operation may be interrupted due to reasons like sudden power-failure or removal (or, loose-
contact) of the Pen Drive, resulting in a partial transfer of records. An interrupted file-write operation makes the file unusable
for appending any further records. Also, the partially transferred records in the interrupted file are lost (but are still retained
inside the ScanLog’s internal memory). That is, the file on Pen Drive exists with the previous records intact (if any) and
becomes a read-only file.
An interrupted file-write operation event is registered by the ScanLog in its internal memory as well as on the Pen Drive that
was being written. Upon resumption of operation, the ScanLog prompts for Recovery of the interrupted operation. Upon
selecting the “Recover” operation, the following sequence of steps is executed.
1. A back-up file of the interrupted file is created to retain the previous records
The back-up file is named BN_S.csv; where, ‘N’ is the last 3 digits of the 5 Digit Code and ‘S’ is the sequential number (1 to
250) assigned to the back-up file. For example; if the 5 Digit Code is 30006 and there does not exist any previous back-up
file, then the new back-up file is named B006_1.csv. If, however, there exists previous back-up file(s), then ‘S’ is assigned
the lowest numeric value (in sequential order). For example; if a Pen Drive already contains back-up files - [B006_1.csv,
B006_4.csv and B006_14.csv] - then the new back-up file is named B006_2.csv.
2. The interrupted file is deleted.
3. A New File with the same name as the deleted interrupted file is created.
4. All the records (including those that were partially transferred during the interrupted operation) are downloaded to the New
File.
The above message implies that there exists multiple ScanLog with the same user defined file names. Assign a different file
name and then download the records.
Case 2 : File does not exist
If the file does not exist, the ScanLog automatically creates a new file with the name stored in its memory and then creates a
File Header using the Instrument Name & the 8 digit UNIQUE ID NUMBER. This is followed by downloading the records. Refer
Figure 3.2.

Pen Drive Checking
Upon inserting the Pen Drive into the USB port, the ScanLog responds by displaying the
message shown in the figure 3.3(a). During this time, the ScanLog checks the file format on the
Pen Drive and also searches for existence of Set.txt file (file containing Instrument Name, File
Name & Channel Names) and any interrupted file-write operation in the previous operation. The
message may last for 5 to 60 seconds depending upon the disc size and occupancy percentage.
In case of any error in reading the Pen Drive or if the Pen Drive dose not respond for more then
60 seconds, the message shown in the figure 3.3(b) is displayed.
Ensure proper insertion of the Pen Drive into the USB port and acknowledge the message by
pressing front panel ENTER key. The ScanLog repeats the device checking operation. If the
error persists; remove the Pen Drive from the port and acknowledge the message (using

Recover, Copy(New), & Re-copy(Old) Operations
The ‘Recover’, ‘Copy (New), & ‘Re-copy(Old)’ options are similar in operations as they all download (copy) records available in
the internal memory onto the inserted Pen Drive. The difference lies in the set of records that is downloaded.
The ‘Copy (New)’ operation downloads the records that are not yet downloaded even once, that is, “new” records. After
successfully downloading the “new” records, the ScanLog retains this set of records as “old” records until next successful
‘Copy (New)’ operation is executed.
The ‘Re-copy (Old)’ operation downloads the set of records that were successfully copied during last ‘Copy (New)’ operation
and were, thus, retained as “old” records. This feature allows re-gaining the copied records in case the Pen Drive fails or
malfunctions after copying records or after inadvertent deletion of the record file from the Pen Drive.
The ‘Recover’ operation copies the records that were being downloaded in the previous ‘Copy (New)’ or ‘Re-copy (Old)’
operation that was interrupted.
Upon selecting one of the above 3 operations, the ScanLog opens an existing file or creates a new file for downloading the
records (refer section “File System for Write Operation”)
If there is an error in opening/creating a file or deleting/re-naming a file (while creating back-up file for ‘Recover’ operation) or
any other errors encountered while downloading the records; the ScanLog displays an appropriate error message. The Upper
Row shows the message while the Lower Row shows the numbers of records pending for downloading.
For various error messages, the operation types for their occurrence and the meaning of the errors, refer Table 3.1 below.

In case of any failure of the USB port itself; one of the following two messages may be displayed on the front panel LCD
depending upon the type of error. The ScanLog needs servicing for any further Pen Drive operations.
If no error is encountered while opening/creating a file for copying the records, the ScanLog
begins downloading the records with the message shown in the figure 3.4(a). The upper row
shows the operation type; Copying for ‘Copy’ operation or Re-copying for ‘Re-copy’ or ‘Recover’
operation. The Lower Row displays countdown of the numbers of balance records.
Upon successful completion of the operation, the ScanLog displays the total numbers of records
copied (or, re-copied) through the message shown in figure 3.4(b). Remove the Pen Drive and
acknowledge the message using ENTER key. The ScanLog reverts to normal RUN mode.
‘Read Set.txt File’ Operation
Upon selecting ‘Read Set.txt File’ operation, the ScanLog opens the file named Set.txt for reading the user defined Instrument
Name, File Name & Channel Names (refer section “File System for Read Operation”).
If there is an error in opening the file or any other errors encountered while reading the file; the ScanLog displays an
appropriate error message on the Upper Row.
For various error messages and their meaning, refer Table 3.2 below.
