Introduction

OM-DAQPRO-5300 is an eight-channel portable data acquisition and logging system with graphic
display and built-in analysis functions

OM-DAQPRO-5300 is battery operated and is capable of sampling, processing and displaying
measurements without connecting to a computer. OM-DAQPRO-5300 is a professional, cost-effective,
compact and stand-alone data logging system that can be used with a wide variety of applications. This
16-bit, high-resolution, eight-channel data logger offers the pros graphic displays and analysis functions
for measuring voltage, current and temperature in real-time.

With its high resolution and fast Analog to Digital converter (ADC), OM-DAQPRO-5300 meets the
majority of data logging requirements in most industrial applications. Its unique ability to display
measured values and analyze them in real-time on a graphical interface minimizes the need to download
collected data to a computer for further analysis.

Every OM-DAQPRO-5300 unit is embedded with a unique serial number and can be loaded with a
descriptive comment for safe identification.

OM-DAQPRO-5300 5300 includes eight input channels for measuring voltage, current, temperature and
pulses. Selectable ranges for each input are 0-24mA, 0-50mV, 0-10V, a large variety of NTC
thermistors, PT-100 RTDs and thermocouple temperature sensors including internal temperature, pulse
counter, frequency meter and up to 20 user defined sensors. The inputs use pluggable screw terminal
blocks for easy connection.

An internal clock and calendar keep tracks of the time and date of every sample measured.

OM-DAQPRO-5300 can automatically activate external alarm events when data is outside a specified
range.

OM-DAQPRO-5300 is very easy to use because all its functions are broken down into an 8-icon menu,
its four buttons can browse every menu and execute any of the commands.

A rechargeable battery powers the data logger, which shuts off automatically after 15 minutes have
passed since the time of the last data recording, the time the last button was pressed, or the time the
last communication was made with the PC.

The OM-DAQPRO-5300 system also comes with the powerful DaqLab software. When the OM­DAQPRO-5300 is connected to a PC, live displays can be viewed at rates of up to 100/s, and automatic
downloads can be carried out at higher rates. The WINDOWS based software can display the data in
graphs, tables or meters, can analyze data with various mathematical tools, or export data to a
spreadsheet.

DaqLab also enables you to setup OM-DAQPRO-5300 and to send advanced commands such as alarm
settings, triggering conditions and text notes.

1. Sensor inputs/alarm output – pluggable screw terminal block (marked Input -1 to Input – 8 from
right to left). All eight inputs can be used simultaneously.

If you are using one sensor, connect it to input 1. If you are using two sensors connect them to
inputs 1 and 2, and so on…

I/O–8 (Input/Output–8) serves either as an input or as alarm output.

To connect a sensor to the OM-DAQPRO-5300 unplug the screw terminal, connect the sensor’s
wires to the terminals, and then plug the terminal back to the corresponding socket on the input
block.

2. Computer USB communication socket – use this socket to connect OM-DAQPRO-5300 to a
computer

Connect the USB Type B plug (square plug) of the supplied communication cable to the OM­DAQPRO-5300 and the USB Type A plug (flat plug) to the computer (see page 32 for USB driver
installation).

3. External DC power supply socket – Plug in an AC/DC 9 - 12V adaptor whenever you want to
save battery power, or to charge the battery when necessary. Connecting external power to the
OM-DAQPRO-5300 automatically charges the internal battery. The adaptor should meet the
required specifications (see section 1.1.10 on page 15).

1.1.3. Sensor types and connections

Each of the 8 input channels of OM-DAQPRO-5300 is multipurpose and can be individually configured
to any of the following types and ranges:

Connect the sensor to the terminal block at the top of OM-DAQPRO-5300:

Figure 2: OM-DAQPRO-5300’s inputs block terminal

Sensors must be added successively, starting with input–1. If a single sensor is used it must be
connected to Input–1. If two sensors are used, they must be connected to Input-1 and Input-2 and so
on…

Alarm output

I/O–8 (Input/Output–8) serves either as an input or as alarm output.

Polarity

Current, voltage, thermocouples and user defined sensors have distinct polarity. Be careful to connect
them in the right polarity.

Frequency/Pulse counter

Connect the signal wires to I/O–8 screw terminals, and select Frequency or Pulse counter for input 1
from the Setup menu. Inputs 2 to 7 are still available for other sensors.

The Frequency/pulse counter is optically isolated from the internal circuitry and can simultaneously
measure a signal source, together with another input.

3 wire PT 100

You have to use two inputs to connect a 3 wire PT 100 You can connect one 3 wire PT 100 to input–1
and input–5, and/or inputs 2 and 6, and/or inputs 3 and 7 and/or inputs 4 and 8.

Connect the single wire to the plus (+) terminal of the first input and the common end wires to the minus
(-) terminals of both the inputs. See Figure 3 for wiring configuration of a 3 wire PT 100 connected to
input–1 and input–5:

12 Chapter 1 OM-DAQPRO-5300

Figure 3: connecting 3 wire PT 100

When working with a 3 wire PT 100 inputs 5 to 8 are not available and you can connect up to 4 sensors.

Sensor mismatch

After logging begins OM-DAQPRO-5300 checks if the sensor type assigned to each channel matches
the attached sensor. If there is a mismatch, OM-DAQPRO-5300 disconnects the corresponding input
and displays a warning message: “Illegal sensor” (see ‘Troubleshooting Guide’ on page 86 for details)

1.1.4. User defined sensors

OM-DAQPRO-5300 provides a simple and straightforward tool for defining up to 20 custom sensors.
Almost any 0 – 10V and 0 – 24mA sensor or transducer is accepted by MultiLogPRO and its electrical
units are automatically scaled to meaningful user-defined engineering units.

The sensor definitions are stored in OM-DAQPRO-5300’s memory and are added to the sensors list.
The sensor’s readings are displayed in the user defined units both on OM-DAQPRO-5300’s LCD screen
and DaqLab software.

To learn how to define custom sensors see section 2.5.9 on page 68

For further manipulating sensors readings use the Analysis wizard (see page 73)

1.1.5. Alarms

Users can define minimum and maximum alarm levels for each input individually.

Chapter 1 OM-DAQPRO-5300 13

OM-DAQPRO-5300 places a small alarm icon next to the corresponding input readings and can
switch alarm output if either level is breached.

To display alarm warnings in real-time OM-DAQPRO-5300 must be in numeric display mode (see page

20).

To learn how to enter alarm levels and to activate alarm output, see section 2.5.1.2 on page 54.

1.1.6. Alarm output

OM-DAQPRO-5300 can trigger an external event (e.g. sound alarm, warning light or oven).

Connect the external current loop to the screw terminals of I/O–8. Be careful to connect the external
power supply in the right polarity (see Figure 4 below).

Figure 4: connecting external alarm device

The alarm output is analogous to electrical switch. In OFF position the terminals of I/O–8 are
disconnected. In ON position they are shortened.

If an alarm output is selected this input/output is set to OFF position. When any active alarm level is
exceeded the output is set to ON. All active alarms must be false to reset the output to OFF position.

The maximum switch load is 50mA, 5V. The output is protected by 50mA reset-able fuse. For higher
loads use a relay.

To learn how to enter alarm levels and to activate alarm output, see section 2.5.1.2 on page 54

14 Chapter 1 OM-DAQPRO-5300

1.1.7. Sensor calibration

OM-DAQPRO-5300 ships fully calibrated. However, further calibration can be applied via DaqLab. The
calibration parameters are sent to OM-DAQPRO-5300 and stored in its memory. See page 61 for
calibration instructions.

1.1.8. Serial number and comment

Every OM-DAQPRO-5300 unit is embedded with a unique serial number and can be loaded with a
descriptive comment to identify its task and location.

To add or edit the comment connect OM-DAQPRO-5300 to the computer and use DaqLab software (see
page 59).

Every time data is transferred to the computer it is labeled both with OM-DAQPRO-5300’s serial number
and comment and then displayed in the graph title.

The serial number is marked on the back of the product. To view its comment, select System information
from OM-DAQPRO-5300’s main menu.

1.1.9. Battery

OM-DAQPRO-5300 is equipped with a 7.2V Ni-MH rechargeable battery. Before you first start working
with OM-DAQPRO-5300, charge the unit for 10 to 12 hours while it is turned off. Battery life is
approximately 40 hours between charges.

If the data logger’s main battery runs out, the internal 3V Lithium battery backs up the memory, so no
data will be lost. The Lithium battery also keeps the internal clock and calendar running.

Note: Before storing the data logger make sure you have unplugged all the sensors and

pressed the OFF key.

1.1.10. Mains Adaptor

The Mains adaptor (AC/DC adaptor) converts mains power (from a wall outlet) to a voltage suitable to
OM-DAQPRO-5300.

• Output: Capacitor filtered 9 to 12 VDC, 400mA.

• Female plug, center Negative.

Chapter 1 OM-DAQPRO-5300 15

1.2. Stand-Alone Operation

One way to program the OM-DAQPRO-5300 is to use its keypad and screen (The other way is to use

to clear the memory

1.2.9. Choose the Right Setup.

1. Sampling rate - The sampling rate should be determined by the rate of change of the
phenomenon being sampled. If the phenomenon is periodic, sample at a rate of at least twice the
expected frequency. Changes in temperature can be measured at slower rates such as once per
second or even slower, depending on the speed of the expected changes. Usually it’s a good
practice to sample at a rate 10 times higher than the expected frequency but for extremely smooth
graphs, the sampling rate should be about 20 times the expected frequency.

Note: Sampling at a rate slower than the expected rate can cause "frequency aliasing".

In such a case, the graph will show a frequency much lower than expected. In
Figure 6 below, the higher frequency sine wave was sampled at 1/3 of its
frequency. Connecting the sampled points yielded a graph with a lower, incorrect
frequency.

28 Chapter 1 OM-DAQPRO-5300

Figure 6: Frequency Aliasing

Manual sampling - use this mode for:

• Recordings or measurements that are not related to time.

• Situations in which you have to stop recording data after each sample

obtained, in order to change your location, or any other logging parameter
(Note: During recording NO CHANGES can be made to the OM-DAQPRO­5300’s configuration).

To start a recording using manual data logging, set the RATE to “manual” and press the Enter

button
collect a sample.

2. Sampling Points - After you have chosen the sampling rate, choosing the number of points will
determine the logging period: Samples / Rate = Logging time. You can also choose the duration of
a run first, and then calculate the number of samples: Samples = Logging time × Rate.

Continuous

In the Continuous mode, OM-DAQPRO-5300 must be connected to the PC and the DaqLab software
must be running. In this mode OM-DAQPRO-5300 can continue logging indefinitely. The data is
automatically downloaded to the computer, displayed in a real time graph and saved every 10 minutes.

OM-DAQPRO-5300 stores the data until its memory is full. You can download this data only if you
stopped logging before this point

To operate in Continuous mode select RATE equal to or less than 1/s and SAMPLES = Continuous.

You can also select Continuous mode directly from the DaqLab software.

Note: OM-DAQPRO-5300 must be set to a display mode other than graphic to enable

1.2.10. Programming Rules and Limitations

The following are some rules and limitations you must take into account when programming the OM­DAQPRO-5300, as OM-DAQPRO-5300 integrates all programming limitations automatically. OM­DAQPRO-5300 will only allow the programming of settings that comply with the rules below.

1.Sampling rate:

The number of sensors in use limits the maximum sampling rate:

1. Maximum sampling rate with one sensor is 4000/s

2. Maximum Temperature sampling rate is 1/s

3. Maximum sampling rate with two sensors or more is 1/s

4. Maximum sampling rate with two or more PT 100 sensors or more is every 10
seconds

5. Maximum sampling rate with eight PT 100 sensors or more is every minute

6. OM-DAQPRO-5300 displays readings in real time at rates up to 1/s

7. DaqLab displays online readings at rates up to 100/s

2.Sampling points:

Increasing the number of active inputs limits the number of sampling points one can choose. The
following condition must be always satisfied:

Number of samples × Active Inputs ≤ Memory

OM-DAQPRO-5300’s memory is sufficient for 512,000 samples.

The table below lists the maximum number of sampling point according to the number of sensors:

Number of sensors Maximum number of sampling points

1 512,000 (exact number: 522,752)

2 256,000 (exact number: 260,608)

3 128,000 (exact number: 129,536)

4 128,000 (exact number: 129,536)

5 64,000

6 64,000

7 64,000

8 64,000

3.Continuous sampling

• Continuous sampling is possible up to a maximum sampling rate of 1/s.

• The data must be presented in a display mode other than graphic.

2.2. Overview

2.2.1. DaqLab On-screen Layout

DaqLab is a comprehensive program that provides you with everything you need in order to collect data
from the OM-DAQPRO-5300 display the data in graphs, meters and tables and analyze it with
sophisticated analysis tools.

The program includes three windows: A graph window, table window, and a navigation window called the
Data Map. You can display all three windows simultaneously or in any combination.

The most commonly used tools and commands are displayed on two toolbars. Tools that relate to all
aspects of the program and tools that control the OM-DAQPRO-5300 are located in the main (upper)
toolbar. Tools specific to the graphs are located on the graph (lower) toolbar.

2.2.2. Working with Projects

Every time you start a new recording, DaqLab automatically creates a new project file. All the information
you collect and process for a given session is stored in a single project file. Each of these files contain all
the data sets you collect with the OM-DAQPRO-5300, the analysis functions you’ve processed, specific
graphs you’ve created, and the DaqLab settings for the recording.

Note: all data sets in a single project must be with the same sampling rate.

, and select one of the following:

2.3.3. Download Data

Whenever data is received from the OM-DAQPRO-5300, it is accumulated and displayed automatically
by DaqLab. There are two modes of communication: online and offline.

Online communication

When OM-DAQPRO-5300 is connected to the PC and programmed to run at sampling rates of up to
100/s, OM-DAQPRO-5300 transmits each data sample immediately, as it is recorded, to the PC. The
software thus displays the data in real-time in both the graph window and the table window.

When OM-DAQPRO-5300 is connected to the PC and programmed to run at a sampling rate of 500/s or
higher, data is accumulated in OM-DAQPRO-5300‘s internal memory. This data is not transmitted to the
PC until the recording period has ended, when the data is automatically downloaded to the PC and
displayed.

Offline data logging

• To download data that was recorded offline, or while OM-DAQPRO-5300 was not

connected to a PC, connect OM-DAQPRO-5300 to the computer, run the DaqLab

36 Chapter 2 Working with DaqLab

program and click Download on the main toolbar. This will initiate the Post­Recording Data Transfer communication mode. Once the transfer is complete, the
data will be displayed automatically in the graph window and in the table window. If
there are several files stored in the OM-DAQPRO-5300, the first download will bring
up the most recent file; the second download will bring up the second most recent file,
and so on.

• If you are logging offline at rates of up to 1/s, you can connect OM-DAQPRO-5300 to

the computer and download the accumulated data at anytime. Apart from during the
transfer period, the data will be downloaded without interrupting the logging process.

• To download a particular file, choose Selective download from the Logger menu,

then select the file’s number in the Download dialog.

• Click Cancel in the Download progress window at any time to stop downloading the

data.

2.3.4. Save Data

Click Save on the main toolbar to save your project. This will save all the data sets and graphs
under one project file.

2.4.1. Display Options

The DaqLab program’s screen consists of three parts: the graph window, table window and Data Map
window. You can display all three parts simultaneously (the default view) or any combination of the
three.

The graph window is the main window by default and is and displayed in the center of the application
window.

In addition to these sections, you have the option to display an on-screen meter for each of the sensors
(see page 48).

2.4.2. Graph Display

Click Graph to display or hide the graph. The default graph display is the data set or sets plotted
vs. time, but you can change the X-axis to represent any of the individual data sets (see page 44).

The graph usually displays all the data sets of a given recording, but you can use the Data Map to
remove one or more of the sets from the graph (see page 49).

In order to keep the graph clear and simple, only two Y-axes are shown on the graph at once. If there
are three curves in the graph, one of the Y-axes is hidden. In order to make this axis visible, select the
corresponding plot with the cursor (see section 2 below).

2.5.8. Calibrating the sensors

1.Calibration options

OM-DAQPRO-5300 ships fully calibrated. However, DaqLab enables you to calibrate any of the OM­DAQPRO-5300 sensors except for the internal temperature sensor, which doesn’t need calibration. The
calibration parameters are sent to OM-DAQPRO-5300 and stored in its memory.

Tips:

• Prior to any calibration procedure you must restore factory defaults

• Calibrating a sensor type applies to all inputs

• Calibrating the PT 100 2 wires sensor applies also to PT 100 3 wires except for fine

offset calibration

• Prior to calibrating any of the thermocouple sensor types, calibrate the Voltage 50mV

sensor as this will set the gain (slope) of all thermocouple sensor types

• The internal temperature sensor needs no calibration

DaqLab employs three different calibration methods Two-point calibration, Offset calibration and
Zero calibration. When selecting a sensor type to calibrate, DaqLab prompts you to the appropriate
calibration procedure:

Sensor Type Calibration method

Current 0 – 24mA Two-point calibration

Temperature

Temperature

Temperature PT-100 2 wire Two-point calibration

Temperature PT-100 3 wire Two-point calibration*

Temperature Thermocouple J Offset calibration

Temperature Thermocouple K Offset calibration

Temperature Thermocouple T Offset calibration

Voltage 0 – 10V Two-point calibration

Voltage 0 - 50mV Two-point calibration

NTC 10KΩ

NTC 2252Ω

Zero calibration

Zero calibration

Two-point calibration

The two-point calibration sets the gain (slope) and offset (intercept) of the sensor's conversion function.

62 Chapter 2 Working with DaqLab

Use the two point calibration to calibrate the voltage and current sensors and the PT100 temperature
sensors.

* To calibrate the PT100 3 wire, first calibrate the PT100 2 wire as the slopes of their conversion

functions are identical. Then proceed to adjust the PT100 3 wire offset.

In some cases you may need to refine your calibration using the fine offset tuning tool.

Offset calibration

To calibrate the thermocouple temperature sensors: TC-J, TC-K and TC-T first calibrate the 50mV
sensor type. That will set the slope for all thermocouple temperature sensors. Then proceed to adjust
the offset using the Offset calibration technique.

Zero calibration

The zero calibration sets only the offset (intercept) of the sensor's conversion function.

Use the zero calibration to calibrate the NTC 10kΩ and NTC 2252Ω temperature sensors.

2.Calibration password

To prevent accidental change of the calibration, the calibration procedure is protected by a password.

The default password is: 1234

To change the password:

1. Click Logger on the menu toolbar, and then click Calibration

2. Click Change Password to open the Change Password dialog box

3. Enter the current password in the Current Password edit box

4. Enter the new password in the New Password edit box

5. Enter the new password a second time in the Confirm New
Password edit box to confirm your new password

6. Click OK

Note: The password must include at least 4 characters and is case sensitive.

9. Click OK

Fine offset calibration

If, after the calibration procedure, OM-DAQPRO-5300 still exhibits some offset value use the Fine offset
tuning tool to correct it.

The offset value is the difference between the value displayed by OM-DAQPRO-5300 and the reference
value. For example if the calibrator is set to 0°C and OM-DAQPRO-5300 reads 1°C the offset value is
+1, but if OM-DAQPRO-5300 reads −1°C then the offset value is −1.

1. Connect OM-DAQPRO-5300 to the PC

2. Click Logger on the menu bar, then click Calibrate sensors

3. Enter the calibration password, then click OK

4. Choose a sensor from the Select sensor drop list and click OK to
open the Sensor calibration dialog

5. Select the Fine offset calibration option

7. Click OK

The calibrated sensor parameters will be saved both in OM-DAQPRO-5300 and DaqLab memories, so
there is no need to calibrate OM-DAQPRO-5300 every time you run the DaqLab program.

Offset calibration:

Calibrating any of the thermocouple sensors comprises of two steps. First calibrate the 50mV voltage
sensor to set the slope of the sensor's conversion function. Then use the calibration procedure
described below to calibrate the sensor's offset.

Chapter 2 Working with DaqLab 65

Chapter 3 Troubleshooting Guide

Symptom Cause of problem

I pressed the ON key on OM-DAQPRO­5300 and it did not turn on.

DaqLab was unable to connect to OM­DAQPRO-5300.

OM-DAQPRO-5300 and DaqLab
displays a warning message: “Illegal
sensor”

I downloaded “unexpected” data.

While running with an active trigger, OM­DAQPRO-5300 does not complete the
data logging.

• Try charging the battery, it may be weak.

• You are using an unsuitable AC/DC adaptor (see

page 15).

• The internal 3V disk battery is dead.

• OM-DAQPRO-5300 is turned off.

• The communication cable is not connected

properly.

• The communication cable is not connected to the

correct PC COM Port.

• There is no available Serial COM Port.

• OM-DAQPRO-5300 measured a voltage drop of

over 5V across an input that was selected as one
of the following types: 50mV, TCK, TCJ, TCT,
PT 100 or NTC.

• OM-DAQPRO-5300 measured a reversed voltage

drop of over -1V across an input that was selected
as one of the following types: 50mV, TCK, TCJ,
TCT or 10V.

• There may be up to 100 files stored in the OM-

DAQPRO-5300. Performing a “Download” means
loading one of them in sequential order. You have
probably loaded an old file accidentally. Try using
Selective download from DaqLab (see page 36)

• The trigger condition has not been fulfilled.

• The trigger condition was fulfilled, but the time

period was too short (less than 300µS).

Chapter 3 Troubleshooting 87

Symptom Cause of problem

I started a new logging and the data
logger stopped immediately afterwards.

The recorded data is “noisy”

OM-DAQPRO-5300’s memory is empty –
there are no stored files or notes.

• First check if the sampling rate was so fast that the

recording began and ended in less than a second.
If this is not the reason, recharge the 7.2V battery
and try again. OM-DAQPRO-5300 monitors the
battery power during the logging. If the battery
voltage is less then 5V, the logging is stopped
automatically.

• With voltage or current sensors, use short

connections between the circuit being tested and
the sensor.

• Avoid working near strong electromagnetic fields.

(e.g. engines, fluorescent lights)

• The internal 3V disk battery is dead.
