CHECKMATE™ DL 1
Introduction CHAPTER 1
The Checkmate™ DL handheld instrument is the convenient and hassle-free way
to program and collect data from Microcor Data Loggers or Corrosometer and
Corrater Remote Data Collectors (RDCs). Checkmate DL can be programmed to
operate with either technology with only a few keypad entries. This portable unit
can store readings of up to 50 different Microcor Data Loggers or Corrosometer
and Corrater RDCs. The intrinsically safe communication between the
instrument and Data Loggers or RDCs enables the user to collect data without
moving the Data Logger or RDC to a safe area. Furthermore, the Checkmate
DL makes transferring stored data to a PC a much simpler process than before,
using the Corrdata Plus® Corrosion Management Software or the Microcor Tools
Software. Refer to Appendix A for Typical System Configuration.

4SPECIFICATIONS
Intrinsic Safety
The gas classification IIC is the most stringent including gases such as acetylene
and hydrogen. This part of the rating relates to the spark energy that is required
to create an explosion.
Gases have a separate classification for explosive tendency based on hot
surface temperatures which are not necessarily the same as the spark ignition
energy. The temperature rating T4 indicates that no temperature of the
equipment exceeds 1350C at 500C ambient temperature even under fault
conditions. This rating includes all listed gases except carbon disulfide (which
requires T5 rating)
Care must be taken with intrinsically safe systems to maintain their carefully
designed integrity. The major features to note:
1. The instrument is intrinsically safe when used with six 1.5V, size AA alkaline
batteries: Duracell MN1500, Energizer E91 or EN91, or Ray-O-Vac 815.
Batteries must be changed only in a non-hazardous area. Do not mix
batteries of different age or part number.
2. Absolutely no substitution of parts or unauthorized repairs may be
undertaken or the certifications are rendered invalid.
3. Only the intrinsically safe cables provided by Rohrback Cosasco
Systems, Inc. should be used between the instrument and the PC
(even when in safe areas). This prevents any excess power from
being passed onto the instrument, which could then be carried into the
hazardous area.

Contents and Unpacking
Carefully remove the instrument from its package. Included in the package you
should find:
• Checkmate DL Instrument (P/N 723701)
• 6 AA batteries
• USB Drive
• Converter, USB to RS232 (P/N 090753)

materials for shipping damage and retain all damaged packing/packaged
materials to support any claim against your freight carrier should this become
necessary.
Battery Installation
The Checkmate DL is supplied with six 1.5 Volt AA alkaline batteries. Batteries
must be installed only in a non-hazardous area. To install these batteries, remove
the rear access panel of the unit (see Figure 3.1) with the Allen wrench provided
and install the batteries with the polarities as indicated on the unit.

6BASICS OF CHECKMATE™ DL
Figure 3.1 Battery Cover of Checkmate DL Instrument
Lithium batteries mounted internally provide alternate power to retain the
configuration and stored data readings when the primary batteries cease. These
batteries should provide 7-10 years of backup capacity. Replacement of these
batteries requires the unit to be returned to Rohrback Cosasco Systems or an
authorized dealer.
WARNING! Batteries must be changed only in a non-hazardous area.
Checking Battery Status
To check that the unit is operational, press the ON key. The following screen
should appear:
Checkmate DL Ver x.xx
Checking BATTERIES
Please Wait!

If the batteries are low or in need of replacement, a warning screen will appear
as shown below. Proceed to a safe area and replace the batteries as indicated
on the Battery Installation section.
WARNING!
LOW BATTERIES
REPLACE NOW!
Exit
If the batteries are good, the instrument will proceed to one of the Standby
displays.
Standby Screens of Checkmate DL
The Standby screens are shown below. For Microcor systems, two additional
screens are displayed prior to entering the Standby screen.
If the Checkmate DL is programmed for Microcor Systems, the Checkmate DL
will display the Microcor Free Readings and then the Time Zone screens
shown below.
Available Memory Space and Standard Time Zone
The Microcor Free Readings and the Time Zone screens are shown below.
The first of the two screens displays the remaining available space for data
transferred into the unit.

8BASICS OF CHECKMATE™ DL
It is required to set the Time Zone into the Checkmate DL from this screen to
configure the Checkmate DL to accurately date and time stamp the readings
acquired from the Data Loggers. Set the Time Zone to either Standard or
Daylight mode on the Checkmate DL by pressing DTZ (F1) to toggle between
Standard and Daylight (the active mode is shown on the top line of the display).
Then use the Up (F2) or Down (F3) buttons to set the UTC offset for the time
zone where the data loggers are located. The correct time zone data is required
because the underlying architecture the Microcor Tools Software is based on
uses a UTC time reference. UTC (GMT) time information is found on computers
in the ‘Date and Time’ settings in Control Panel on Windows Operating Systems.
NOTE: If the clock time on probe readings is incorrect by up to 36
hours, check that the Checkmate DL is set to the correct
time zone. This may be done manually from the “Time Zone”
screen shown above.
Checkmate DL Keypad
The Checkmate DL features a keypad with 34 keys for the alphabet A through
Z and numerals 0 through 9. The numerals are shared with letters F through P
and S. Switch between these letters and numbers using the Alpha/Numeric key.
There are also four soft keys, F1 through F4 (as shown below). The soft keys
are multi-function keys used to make on-screen selections.
Checkmate DL Firmware Version
The Checkmate DL firmware version is displayed on the first screen of the
instrument when it is turned on regardless of the data collection system.

Configuring Checkmate DL for Corrdata Systems
If the Checkmate DL is programmed for the Microcor System, it can be easily
changed to the Corrdata System as described below.
WARNING! When switching Checkmate DL between Microcor
and Corrdata Systems, all stored data will be erased!
Be sure to transfer all stored data to the PC prior to
changing the data collection system (see appropriate
chapters for more details on data transfer).
From the Standby display, press Mate (F4) then select Mate Type (F3) from
the Mate Functions display. Press Yes (F1) to change the Checkmate DL from
Microcor technology to Corrdata technology.
Setting the Time and Date
The Checkmate DL has its own internal clock so that individual probe readings
are automatically time and date stamped.
To set the internal clock Time and Date, from the Standby display, press SetUp
