Datalogger Programmer with Printer
Model 42276 – Temperature and Humidity
Model 42266 – Temperature only
Introduction
Congratulations on your purchase of the Extech 42276 or 42266 Datalogger
Programmer with Printer. The Programmer is a docking station for the 42270
Temperature/Humidity or the 42260 Temperature only Datalogger. It allows the user to
configure, download, and print data from the Datalogger. The removable Datalogger
module stores up to 16,000 readings. The programmer allows the user to configure the
Datalogger module as well as print readings and display details of the recorded data.
Careful use of this device will provide years of reliable service.
The datalogger display will not switch on until
activated by the programmer.
The datalogger module display will not switch on until it is activated by the programmer in
the LOGGER SET menu as described later in this manual. In LOGGER SET the user
selects the type of recording activation. When the logger begins to log data, the display
and status LEDs will switch on.

Datalogger Module Displays
Datalogger LCD Display
REC: Displayed while logging readings. Read the ‘Recording
Status’ section for further details.
HI and LOW: Displayed when the High or Low Alarm limit is
exceeded. See ‘Alarm Status’ below for further information.
RH%: Relative Humidity (42270 only)
C or F: Temperature units.
COMM: Appears when Datalogger is communication with a PC.
Note: The datalogger module display will not switch on until it is placed in the docking
station, connected to the PC, and activated by the software in the LOGGER SET menu as
described later in this manual. In LOGGER SET the user selects the type of recording
activation. When the logger begins to log data, the display and status LEDs will switch on.
Recording Status Indication
Both the RED status LED and the display indicator ‘REC’ will flash every 5 seconds if the
sampling rate is set to 5 seconds or higher. If the sampling rate is set lower than 5
seconds, the indicators will flash every 1, 2, 3, or 4 seconds as programmed.
ALARM Status Indication
Both the YELLOW status LED and the display indicator ‘ALM’ will flash when the recorded
value is higher than the user programmed High Alarm value or lower than the Low Alarm
value. The Alarm status LED and the ‘ALM’ display indicator flash every 5 seconds if the
sampling rate is programmed for 5 seconds or higher. If the sampling rate is set lower than
5 seconds, the indicators will flash every 1, 2, 3, or 4 seconds as programmed.
Low Battery Indication
‘LO’ is displayed when the lithium battery voltage approaches the critical operating level.
To replace the battery, refer to the Battery Replacement section of this manual.

Print Modes
The Programmer prints data in three modes: Text Mode (a brief summary followed by a
line by line data list); Graph Mode (similar to Text but with a series of graphs representing
all recorded data); or Report (Logger Summary) Mode (similar to Graph Mode but has only
one graph representing all the data in the set). Example printouts are provided below.

Datalogger Start Modes
There are three methods by which the Datalogger can be programmed to start recording.
The three modes are: IMMEDIATE, SCHEDULE, and MAGNETIC. The three methods are
described below:
1. IMMEDIATE: Datalogger starts recording as soon as this method is selected.
2. SCHEDULE: A time and date can be programmed prompting the Datalogger to
begin recording at a specific point in time. Schedule the time and date by first
selecting SCHEDULE under the OTHER SETTINGS parameter on the LOG page
and then setting the Time and Date as prompted.
3. MAGNETIC: When a magnet is passed over the back of the Datalogger, recording
starts.
Maintenance
Battery Replacement
The battery compartment is located on the bottom of the Programmer. When the batteries
are weak the display may appear very dim, blank altogether, or display ‘LOW BATTERY’.
Open the battery compartment by first laying the instrument face down on a soft surface
and then lifting the compartment latch. Remove and replace the four ‘AAA’ 1.5V batteries
observing polarity.
Printer Paper Replacement
When the instrument’s paper roll is depleted, open the paper compartment located above
the paper feed by lifting the compartment latch. Cut the beginning of the new paper roll into
a point (see diagram) before feeding it through the printer.
Cut paper into a point. Feed paper into printer
pointed end first.
Place the new roll of paper in the compartment (pointed end first) and feed it through using
the FEED button. A 5-pack refill of printer paper is available using part number 422378.
Cleaning and Storage
Use a damp cloth to wipe the instrument housing periodically. Store in a cool, dry location
with the batteries removed.
