1.0 Introduction
Thank you for purchasing a Setra DATUM 2000™ meter or manometer.
Setra’s DATUM 2000™ is a compact dual channel meter with a 4 1/2 digit LED display
designed to mate with one or two transducers or transmitters with a connection.
The DATUM 2000™ manometer is a single unit which combines a DATUM 2000™
meter with a Setra transducer. The Setra transducer is connected to the Channel
One inputs of the manometer, with Channel Two inputs available for external
connection to another Setra transducer or transmitter.
The DATUM 2000™ meter and manometer are easy to use and install and may be
used on a benchtop or panel-mounted.
Important
Please familiarize yourself with each set of instructions before attempting to install
you meter or manometer or perform a procedure. The meter has a “time-out” safety
feature to prevent miscalibration. Every time a new message is displayed during a
procedure, you have 30 seconds to respond. If you don’t respond within 30 seconds
the meter will reset itself to normal operation.

2.0 Connecting a transducer to the DATUM 2000™
Note: If you purchased your Datum 2000™ factory calibrated with a Setra pressure
transducer or transmitter, a 10 foot cable/connector assembly has been provided.
Therefore, this section may not be applicable. Go to page 7.
The DATUM 2000™ has two groups of input terminals, one for each channel. Figure
B (page 6) shows the terminal block connector on the back of the DATUM 2000™
and describes each position of the connector. Figure A shows a typical setup of a
DATUM 2000™ with a single transducer.
The DATUM 2000™ provides a ground referenced 12 volt and 24 volt excitation. The
24 volt excitation is available on pins 5 and 11. The 12 volt excitation is available
only on pin 10. (If two 12 volt transducers [transmitters] are being used, both
units must be connected to pin 10). DO NOT USE THE EXCITATION FROM THE
METER TO POWER ANY OTHER DEVICE BESIDES THE 1 OR 2 TRANSDUCERS OR
TRANSMITTERS THAT THE METER IS DISPLAYING. UNDER NO CIRCUMSTANCES
SHOULD MORE THAN 60 MA BE DRAWN FROM THE DATUM.
2.1 Transmitters (2 wire devices)
Connect the + excitation to pin 5 (CH2: pin 11) to supply 24 volts to the transmitter.
Connect the - excitation to pin 8 (CH2: pin 14) to return the signal to the DATUM
2000™.
2.2 Transducers (3 wire or 3 terminal devices)
Connect the + excitation to pin 5 (CH2: pin 11) to supply 24 volts to the transducer.
IF YOUR TRANSDUCER REQUIRES 12 VOLT EXCITATION, CONNECT THE +
EXCITATION TO PIN 10 (CH2: PIN10).
Connect the - excitation to ground, pin 9 (CH2: pin 15).
Connect the + output to +IN, pin 6*(CH2: pin 12).
Connect the -IN terminal, pin 7*(CH2: pin 13) to ground, pin 9 (CH2: pin 15).
Connect the shield to ground, pin 9 (CH2: pin 15).
5
2.3 Transmitters (4 wire or 4 terminal devices)
Connect the + excitation to pin 5 (CH2: pin 11) to supply 24 volts to the transducer.
If your transducer requires 12 volt excitation, connect the + excitation to pin 10
(CH2: pin 10).
Connect the - excitation to ground, pin 9 (CH2: pin15).
Connect the + output to +IN, pin 6*(CH2: pin 12).
Connect the - output to -IN, pin 7*(CH2: 13).
Connect the shield to ground, pin 9 (CH2: pin 15)
*Note: THE OUTPUT OF THE SETRA TRANSDUCER INSTALLED IN THE DATUM
2000™ MANOMETER IS AVAILABLE ON PIN 6 AND 7. DO NOT APPLY AN
ELECTRICAL SIGNAL TO CH1: PIN 6 OR CH1: PIN7. A SECOND TRANSDUCER
MAY BE CONNECTED ONLY TO CH2: PIN 12 OR CH2: PIN 13.

3.0 Operating notes
3.1 OvEr and UndEr messages
In addition to displaying the numeric pressure reading, the DATUM 2000™ may
also display “UndEr” and “OvEr”. If the pressure reading exceeds +31999 (disregard
decimal point), the display will not show the input pressure, instead it will display
“OvEr”. If the pressure reading is less than -9999 (disregard decimal point), the
display will not show the input pressure, instead it will display “UndEr”.
3.2 Sampling rate
The DATUM 2000™ will read the channel, 2 to 3 times a second. The speed of the
update is determined by the voltage of the channel being read. If the meter has two
channels calibrated, it will display each channel for 8 readings, and then switch to
the other channel. The exact time the meter will display a channel is dependent on
the voltage of that channel. Each channel will be displayed for approximately 3 to
4 seconds.
3.3 Locking onto a channel
Press the HOLD/mode key to force the DATUM 2000™ to continuously display the
present channel. Upon power-up, the DATUM 2000™ will display both channels.
3.4 Displaying both channels
Press the SCAN/adj key to for the DATUM 2000™ to resume displaying both channels
3.5 Manometer analog output
The output of the Setra transducer installed in the DATUM 2000™ manometer
is available at the rear terminal strip on pins 6 and 7 and marked channel 1 +IN,
channel 1 -IN.
3.6 Rapidly changing input signal
For a signal whose magnitude is increasing very rapidly, the DATUM 2000™ can
select the wrong integration time. This can cause a single reading overflow of the
A/D converter. This overflow can cause the sign of the reading to be incorrectly set.
Such an occurrence can cause an improper setting of the incorrectly set. Such an
occurrence can cause an improper setting of the alarms. This condition will self-
correct once the input signal has stabilized. This occurrence will rarely, if ever, be
seen.
3.7 Test mode
There us a test mode in which the DATUM 2000™ will display the output of the A/D
converter reading of Channel 1 without performing the units conversion. This mode
is accessible only by holding both the SCAN/adj and HOLD/mode keys down when
the power is applied to the DATUM 2000™. If you accidentally enter this mode, you
can exit by pressing wither key.

4.0 User setups
The menu tree below represents the meter program structure. To enter the menu
and select a channel, press and hold the SCAN/adj and HOLD/mode keys for 8
seconds, then release; the display will alternate between "cal" and "noYes" for ten
seconds.* To specify "yes" and select "CH1", press and hold the HOLD/mode key
until "Ch1" displays. To specify "no", press and hold the SCAN/adj key. The display
will return to normal operation. (To select "CH2": With "Ch1" displayed, press and
release the SCAN/adj key to display "Ch2"). When choosing menu options, you have
30 seconds to press a key before the meter defaults to normal operating mode.
To view the commands listed for the display channel, press and release the HOLD/
mode key to display "ALAr". Then press and release the SCAN/adj key (repeat) to
display each command until the display returns to normal operation.
Note: If the meter has not been calibrated at the factory, when the meter is turned
on, the display will alternate between "cal" and "noYes".
9
5.0 Set "offset" (please read before attempting procedure)
Note: The channel must be calibrated before the offset is adjusted.
The "OFFSET" command allows you to adjust the reading relative to a known value.
To set the "OFFSET" use the following procedure:
Step 1.
Press and hold the SCAN/adj and HOLD/mode keys for 8 seconds, then release; the
display will alternate between "cal" and "noYes" for ten seconds.
Step 2.
To specify "yes" and select "CH1", press and hold the HOLD/mode key to display
"CH1". (To select "CH2": With "CH1" displayed, press and release the SCAN/adj key
to display "CH2")
Step 3.
Press the HOLD/mode key to display "ALAr".
Step 4.
Press the SCAN/adj key to display "OFFST".
10
Step 5.
Press the HOLD/mode key to display the number "0".
Note: The decimal point that was set during calibration (CAL_U, CAL_C) will be
displayed.
Step 6.
Set the value you wish the meter to display at the presently applied pressure.
Press the SCAN/adj key to move the numbers up (+).
Press the HOLD/mode key to move the numbers down (-).
When the desired number is reached, press the SCAN/adj and HOLD/mode keys
at the same time. The number will flash repeatedly. Then, press the SCAN/adj key
to readjust the number or the HOLD/mode key to accept it. After the number is
accepted, the meter will display "bUSY" for 10 seconds and then resume normal
operation"
