Introduction

The Saf-T-Log is a thermocouple meter which records temperature readings on demand for later download
to the PC. A list of items to be measured is created in checklist form using the Saf-T-Log software and
subsequently downloaded to the Saf-T-Log handheld meter. The Saf-T-Log is capable of storing up to 7
checklists on the device. Each reading that is stored on the Saf-T-Log includes the date, time, measured
value, high and low target values, Pass/Fail result, corrective action and user name of the person who
recorded the temperature reading. Checklists can include Yes/No questions in addition to temperature items.

Terminology

Checklist A list of up to 300* Items and up to 25 Users created in the computer (PC) software. The
checklist is stored in the Saf-T-Log during the ‘sync operation’.

Footnote Additional information can be typed into this section at the end of the report.
Item User definable checklist parameter which can have individual ‘high’ and ‘low’

temperature limit assigned. Includes temperature and Yes/No questions.

Corrective A pre-set action that a user can select on the Saf-T-Log device after a “failed” reading. Can be
Action a temperature or Yes/No corrective action.

Note A short message or corrective action that can be added against each individual measurement,

if required, to explain anomalies in data once downloaded to the PC.

Saf-T-Log Basics

Auto-Off

Auto-power off will occur 10 minutes after the last button press to conserve battery life. This may be disabled
by entering the Instrument Menu. The Instrument Menu is entered by simultaneously pressing the Up () and
Down () buttons and scrolling to the option “Change Auto-Off”. Press ‘Rec’ button to enter the function,
scroll to the desired option “AutoOff ENABLED” or “AutoOff DISABLED” and pressing ‘Rec’ button to select.
The Saf-T-Log will store this setting until changed by a user.

Battery Indicator

The battery indicator is located at the upper right corner of the instrument display. When the icon shows
almost empty it is recommended to change the batteries. See page 18 of this manual for instructions on
changing the batteries. When the Saf-T-Log instrument is connected to the PC and the desktop software is
open, the software will prompt the user to change the batteries if the battery power is low.

Selecting a Checklist

The Saf-T-Log is capable of storing up to 7 checklists on the device at a time. One checklist is active at a
time and can be switched for another one on the device. To view the current checklist, cycle the power and
on startup the name of the checklist that is active will be displayed. Alternatively, the active checklist can be
viewed in the Instrument Menu by simultaneously pressing the Up and Down buttons, scrolling to the ‘Change
Checklist’ menu and pressing the Record button. The active checklist will be displayed first. To change to
another checklist scroll to the desired checklist and press the Record button. Press record again to exit the
menu.

User List

The current user may be changed on the Saf-T-Log device without reconnecting to the PC. The ‘User’ list for
the current checklist stored on the Saf-T-Log is accessed by pressing the ‘Up’ () and ‘Down’ () buttons
simultaneously to enter the Instrument Menu. Scroll to the option “Change User” and press the ‘Rec’ button
to view the list of users that were setup in the Checklist stored on the Saf-T-Log device. Scroll to the desired
user to select and press the ‘Rec’ button to store the entry and exit the Instrument Menu. The new user is now
active. Alternatively, to display the current user selected on the Saf-T-Log device, press and hold the ‘ON /
OFF’ (Backlight) button for 3 seconds at startup. Note: When changing checklists on the handheld device, it is

important to know that the user list will also change with the active checklist. It is recommended to check the
current user when changing to a different checklist.

Temperature Unit Display

The temperature unit display (°F or °C) can be changed by use of the Saf-T-Log software. The device will
display temperature in the scale that the Checklist was set to display in. See section entitled ‘Changing Saf-T­Log Temperature Units (°F or °C)’ for complete instructions (page 9). Note: When using multiple checklists,

the first checklist being loaded will set the default temperature scale for the rest of the checklists.

Selecting Items

In measurement mode, the Up () / Down () arrow buttons are
used to scroll through the ‘Checklist Items’. The current ‘item name’
will be displayed in the Alpha/numeric portion of the LCD display.
By holding down the Up () or Down () buttons the scrolling
speed will increase. The corresponding temperature limits (HI) and
(LO) are displayed in the upper left portion of the display. For Yes/

No items, ‘Yes or No’ will be displayed. ‘PASS’ will be displayed if
the temperature being measured is between the high and low limits. ‘FAIL’ will flash if the temperature being
measured is outside the high and low limits.

Record

For temperature items pressing the ‘Record’ button saves the current temperature reading, together with date
and time, user, item name that is currently displayed, checklist name, PASS/FAIL status and limits to memory.
If the reading falls outside of the acceptable limits, the user is prompted to store a corrective action.

For Yes/No items, pressing the ‘Rec’ button enters the Yes or No selection function in the lower display.
Scroll to either ‘Yes’ or ‘No’ to store the desired value. If ‘No’ is selected, the user is prompted to include a
corrective action from the list of Yes/No corrective actions that is stored for the current checklist. The unit can
store up to 1,000 readings. After reaching 1,000 readings, the unit will no longer save readings and display
‘Memory Full.’

Instrument Menu

To enter the Instrument Menu on the Saf-T-Log device, press and hold the Up () and Down () arrows
simultaneously. Within the Instrument Menu the user can: view saved readings, change checklists, change
the current user, access the instrument info menu to view date, time, firmware version, instrument name,
Checklist Name, calibration info, and TRIM value; and change the Auto-Off setting.

Software

Synchronization

Install the Saf-T-Log software onto your PC following the instructions in the Quick Start Guide. The Saf-T-Log
software consists of two parts, the Saf-T-Log software and the Saf-T-Log Synchronization window. When the
software is installed 2 icons are added to the computer desktop.

An icon on the desktop is used to access the main Saf-T-Log software.

A synchronization icon is placed in the system tray on the right hand end of the Windows taskbar.
This may be in the ‘Hidden Icons’ section () on Windows 7 and above.

3 items are also installed in the ‘start menu’.

When the Saf-T-Log instrument is connected to the computer via the supplied USB cable the software
automatically starts the data transfer from the Saf-T-Log instrument to retrieve the data stored in the device.
The ‘Saf-T-Log Connect Status’ windows opens automatically and will update while the stored readings are
being transferred to the PC. In the status window, the user will see the Saf-T-Log name, Checklist names,
number of saved readings, the number of high and low alarms and number of failed Yes/No readings. Once
the download is complete, all readings may be erased from the Saf-T-Log memory and saved to the PC. The
user may select to either automatically erase all readings after download or purge readings at a later date
(see Settings on Page 8).

Note: The buttons ‘Create New Checklist’, ‘Edit Existing Checklist’, ‘Choose New Checklist to send to Saf­T-Log’, and ‘Keep Existing Checklist’ are only displayed on the ‘Saf-T-Log Connect Status’ window after the
‘Add Notes and Corrective Actions’ window is closed.
