2. Remove the clip-on foot cover by lifting up on the cover and releasing it from

the stabilizing arm at the bottom of the recorder. This exposes the rubber feet
and stabilizing arm. The rubber feet protect the bench top surface.

DO NOT ATTEMPT TO SET THE RECORDER UPRIGHT ON
THE BENCH WHEN THE CLIP-ON FOOT COVER IS IN
PLACE. THE RECORDER WILL TOPPLE OVER.

Figure 2-1. Foot Cover Removal

CAUTION

Clip

Cutaway View

!

3. Swing out the stabilizing arm and extend it towards you. Figure 2-2 shows how

to swing out the stabilizing arm. Make sure the slot in the stabilizing arm
extends out the rear of the recorder.

Figure 2-2. Swiveling Stabilizing Arm

When the recorder is in normal operating position (chart
door is closed), the stabilizing arm should be pushed to
middle position (the bumps on the arm will click in place
under the recorder). Refer to Figure
2-3a.

Before opening the chart door, pull the stabilizing arm out to
its full extension position to provide full stability. Refer to
Figure 2-3b. After closing the door, return the arm to its
middle position. Refer to Figure 2-3a.

Note that the arm extends towards the front or rear of the
case. If the unit is placed on a bench top snug against the
wall, extend the stabilizing arm fully to the front of the unit.
Refer to Figure 2-3b.

2.2 Mounting the Recorder on the Wall

To mount the recorder on the wall, first locate the wall mounting holes using the
template provided in the wall mounting kit. Leave the decorative foot cover
(Figure 1-1, item #18) in place*. After drilling the holes, insert the wall anchors
and put in the screws, leaving

1

⁄8 inch (3 mm) between the screw heads and the
wall. Hang the recorder by positioning the two (2) “keyholes” in the rear cover
over the screw heads.

* If the decorative foot cover is not in place, go through the following steps to

reinstall the cover (if desired):

1. Place the recorder on the table (so it is front face up).

2. Roughly position the foot cover so the clips are in line with the stabilizing
arm. Gently “stretch” the clips out and position over the arm as shown in
Figure 2-4a.

3. Once the clips are in place, gently slide down until the foot cover is even
with the front of the recorder as shown in Figure 2-4b.

2.3 Using Batteries

The recorder operates on either four “D” size non-rechargeable alkaline batteries
or a universal (100-240 Vac, 50-60 Hz) ac adapter.

In the event of ac power failure, the unit will switch over to
battery power automatically. Keep a fresh set of batteries in
the unit in case of power outage.

2.3.1 Installing Batteries

You may power the recorder with four “D” size alkaline batteries. Under normal
conditions, the recorder operates full time on battery power for up to three
months when using fresh alkaline batteries. When replacing batteries, we
recommend that you use Alkaline “D” size batteries for long life and for best
performance at low temperatures.

To install the batteries (refer to Figure 2-5):

The battery icon on the LCD shows the status of the batteries as shown below.

Figure 2-6. Battery Warnings

2.3.2 Connecting ac Power

The recorder can be ac powered using the universal 100-240 Vac adapter
supplied. The dc power jack is located on the right side of the unit (refer to
Figure 1-1, item #6.). The ac adapter provides 9 Vdc @ 1.7A power output and
comes with a 1.8 meters (6 ft.) long cable.

The following parameters are stored in the non-volatile
memory and will not be lost when batteries or main power
are removed

• Chart speed & scale

• High & low alarm set points for the two channel

• Chart Data points

When the recorder runs only on AC adaptor, and the main power restores after a
power failure, the recorder turns on automatically without pressing the Power
Key. All LCD segments turn on momentarily, then there is a 20 second delay
before the revision screen. This only happens when the power is removed
without pressing the Power Key. The pens go to the home position and back to
the correct chart scale everytime the recorder powers up.

2.5 Installing and Removing Pens

The recorder already comes with the two pens installed. While the unit is turned
off, open the recorder door and remove the pen caps from the two pens. Place
the pen caps on the two posts as shown in Fig. 2-11.

2.5.1 Installing the Pens

The recorder uses two different colored pens to record information. The red
(upper) pen records temperature. The blue (lower) pen records relative humidity.
Pen life varies with use and climate. Under normal operating conditions, pens
last at least one month. We recommend that you install a fresh set of pens after
every month of use.

To install pens:

1. Make sure the recorder is turned off. The recorder door should be closed.

2. Examine the location of the pen arms through the window in the recorder door.
a. If the pen arms are offset as shown in Figure 2-9, continue to Step 3:

Figure 2-14. Setting Alarms and Time Clock

Press key to get into the Configuration mode. In this mode, you can set
High & Low alarm points as well as the Time Clock as shown in the flow chart
on the previous page.

You can exit the configuration menu at any time by pressing the key. The
high & low alarm set points are stored in the non-volatile memory. Removing
power (ac adapter or batteries) will not affect the alarm settings. The real time clock
has its own rechargeable battery back up. The clock continues to operate when the
main power is removed for about 14 days. There is no need to change the real time
clock battery since it gets charged every time the main power is present.

The recorder has two built-in Relays and provides an additional two voltage
outputs to drive external mechanical relays. There is a 10 position terminal block
in the back of the recorder. It provides the two relay contact closures & two
signal outputs to drive external mechanical relays as shown in Fig 2.14. In order
to do your wiring, remove the terminal block from the back of the recorder.
Connect your wiring, then plug the terminal block back in its place.

Figure 2-15. Relay Terminal Block Wiring Diagram

When the recorder is in alarm condition, the high or low alarm icon
and the channel no. flashes on the display. The unit beeps and the
corresponding relay output turns on (Built-in Relay energizes-contact
closure- and/or relay voltage output goes high). You can disable the
high or low alarms by going thru the configuration menu and
pressing the SET key to disable.
If you are switching inductive loads across Relay contacts, it is
recommended to connect a Varistor across the relay contacts to
protect the contacts from the rush current during the switching

2.10 Open/Out of Range Input

If the input to the recorder is open or out of range, the chart motor continues to
run but the recorder handles the situation as follows:

1. Temperature/Humidity Model: When the sensor probe is disconnected, the

pens go to the home position and the display shows “Prb Err”. When the
probe is out of range, the display flashes.

2. Dual Thermocouple Model: When any of the two thermocouple inputs open

up, the pens go to the home position, and the display shows “Prb Err”. When
the input is out of range, the display flashes.

3. Dual Process input Model: When the two inputs are out of range, the display

flashes.

2.11 Pen Jamming

Each pen drive mechanism has two optical sensors. One is to detect the home
position, the other is to detect pen movement. If the pen drive mechanism skips
steps due to wear & tear or dirt & dust over a period of time, the recorder can
compensate for it so that the pens are at the right location on the chart. If the
pens have too much friction or get jammed for any reason, the recorder detects
the situation. It turns off both the pen and the chart motors. It continues to
display the parameters on the LCD and stores data in the memory. The Chart
icon starts to flash to indicate Pen Jamming.

Once the pen drive mechanisms are serviced, and the recorder is powered back
on, the unit continues to operate normally and the chart icon flashing will
disappear.

2.12 Pen Re-scaling

Each or both pens can be re-scaled within the range of the input sensor. Here are
the standard chart ranges for the three models:

Temperature/ Humidity Model -17.7 to 49ºC (0 to 120ºF)

0 to 100% RH

Dual Thermocouple Input

Type K -40 to 560ºC (-40 to 1040ºF)

Type J -40 to 260ºC (-40 to 500ºF)

Type T -40 to 160ºC (-40 to 320ºF)

Dual Process Input 0 to 100%

The pens can be re-scaled thru RS232 from the PC using certain commands. See
Chapter 3 for more details. Once the pens are re-scaled, the Chart icon turns on.
The unit remembers the new pen scales even if the main power is removed. The
chart icon will disappear if the pens are scaled back to factory settings.

mode, the lights say on until pressing the key again to turn them off.

2.14 Lock/Unlock Keypad Functions (White Box)

You can Lock/Unlock the front panel keypad functions by pressing & holding
the key for 3 seconds. When in lock mode, the lock icon comes on and the
configuration menu will be inactive (Config, Set, Yes, No). When in unlock
mode, the Unlock icon comes on and all the keys are active.

2.15 pH & RTD Input Chart Recorder

Model CTXL-pH takes pH probe and RTD sensor directly. The pH probe can be
connected directly to the recorder via a BNC connector. The RTD sensor from the
pH probe can be connected to the terminal block below the BNC connector.

The recorder measures the pH and RTD temperature inputs. It compensates the
pH input for the RTD temperature. If the pH probe does not include an RTD
sensor, you need to add a 110 ohms resistor (included with the recorder) across the
terminal block. This will set the temperature input to a fixed value (about 26ºC).

pH Input Calibration Procedure

The pH input is calibrated at 4 & 7 pH values. From the Hyper terminal, you can
use the following PC commands to calibrate the pH input:

I1L<CR> Channel 1, Calibrate @ 4 pH @ 25ºC Buffer (+177.5 mV)
I1U<CR> Channel 1, Calibrate @ 7 pH @ 25ºC Buffer (0 mV)
I1C<CR> Save pH Calibration

RTD Temperature Input Calibration Procedure

The RTD input is calibrated at 20 & 80ºC values. From the Hyper terminal, you
can use the following PC commands to calibrate the RTD input:

I2L<CR> Channel 2, Calibrate @ 20ºC (RTD = 107.8 ohms)
I2U<CR> Channel 2, Calibrate @ 80ºC (RTD = 130.9 ohms)
I2C<CR> Save Temperature Calibration

pH Offset Adjustment Procedure

pH sensors will deteriorate and drift over time. You can
introduce an offset to the pH channel to compensate for
this drift. From the Hyper terminal, you can use the
following PC commands to introduce pH offset:
OF5<CR> Introduce +0.05 pH offset
OF125<CR> Introduce +1.25 pH offset
OF-7<CR> Introduce -0.07 pH offset
OF-175<CR> Introduce -1.75 pH offset
OFD<CR> Resets the pH offset back to Zero
OFC<CR> Displays the current pH offset value,
for example: 0020 means +0.20 pH

3 PC Communication

You can communicate with the CTXL recorder thru RS232 port from a PC. There
are a number of PC commands that allows the user to do the following
functions:

• Get the data (Like Temperature & Relative Humidity) in real time. This is the

same data displayed on the LCD.

• Download the stored chart data from the recorder to the PC. It will save the

data into a data file. It can then be imported into the Excel spread sheet
program for further review and analysis.

• Re-scale the Chart paper for one or both Pens to any range within the input

operating range.

• Reset the Chart scale back to the Factory standard scales.

You can initiate the PC commands from the Hyper terminal or can develop your
own program and incorporate these commands. Here are the steps to work from
the Hyper terminal:

• From Start Programs Accessories Hyper Terminal

• Create a name for your communication

• Set the communication settings as follows (In the Properties Menu):

- COM port (1, 2, 3)

- Baud Rate (9600)

- Data Bits (8)

- Parity (None)

- Stop Bit (1)

- Flow Control (None)

3.1 Get Display Data in Real Time

You can get the data for channels 1 & 2 in real time. It will be the same data
displayed on the LCD. The following two commands perform such functions.

In the Temperature/Humidity Model, the temperature data is multiplied by 10
using the AT command.

Please note that all the PC commands terminate with a Carriage Return. In the
Example section of the following tables, the PC commands are in Bold, and the
response is in regular text.

PR1 Re-scale the Pens to the PR1; Rescaled

standard Factory scales

In the above example, we are re-scaling both Pens as follows:

Temperature Pen: 50 to 90ºF (Standard: 0 to 120ºF)

Humidity Pen: 40 to 80% RH (Standard: 0 to 100%RH)

After issuing the PR0 command, the new Pen scale values will take affect, otherwise
the previous scale values will remain. The Chart icon comes on to indicate new chart
scale. The new scale is stored in the non-volatile memory. To restore the Pen scales
back to the Factory settings, you need to issue the PR1 command.

The rescaling value can be a negative number on model CTXL-DTC. For example,
you can issue a PC command: PUB-100 meaning the bottom of chart for channel 1
starts at -100.

3.3 Download Stored Chart Data from Recorder to PC

You need to create a Text file for saving the data from the recorder before issuing
the MD command. While in Hyperterminal, go to: Transfer Capture Text
(Create a Text file) Start

Command Description Example

MD Download stored Chart data & save it in a data file MD;

MI Erase stored Chart data from recorder’s memory MI;Done

When you issue the MD command, it will download the Chart data (Chan 1 & 2)
stored in the non-volatile memory of the recorder. It will save the data into a text
file which can be imported into the Excel spread sheet program. Depending on
the amount of data stored in the non-volatile memory of the recorder, the data
transfer could take up to 3 minutes.

Here is a sample of data downloaded from the recorder.

3.4 Humidity Probe Calibration Procedure (CTXL-TRH)

This is a two point humidity calibration, 33% RH and 75% RH. The temperature
does not require calibration although it can be certified at room or any other
temperature within its operating range. Before the humidity calibration, you
must record the humidity reading of the probe at 33% RH & 75% RH
environments. If the reading accuracy at these two points are within +/-3% RH,
no calibration is required. Otherwise the probe needs calibration as described
below:

Example: The probe humidity reading at 33% RH is 37% RH and at 75% RH is
72% RH.

(PC commands are in Bold)

1. Connect the CTXL recorder to a PC with the RS232 cable provided.

2. Run HyperTerminal program from the PC. The COM port setting are:

Baud rate: 9600
Data Bits: 8
Parity: None
Stop Bit: 1

3. Turn on the power to the CTXL. The probe does not have to be at any specific

humidity environment (Regular room environment).

4. Type HH then press Enter key from the Hyper Terminal. The following

message shows the previous two calibration data (Factory Default setting are
33% RH and 75% RH) saved in the CTXL memory.

HH; Humidity calibration saved data are:
00033
00075

5. Type HC then press Enter key to start the humidity calibration, and the

following message will appear.

HC; Humidity calibration begins,
Please type HUL followed by the measurement value at 33% RH.

6. Type HUL37 then press Enter key. (37 is the value that the probe was reading

at 33% RH humidity), and the following message will appear:

HUL37; 00037
Please type HUH followed by the measurement value at 75% RH.

7. Type HUH72 then press Enter key. (72 is the value that the probe was reading

at 75% RH humidity), and the following message will appear:

HUH72; 00072
Humidity calibration is done.
00037
00072

8. Now the humidity calibration is complete and the probe reading should be in

specs.

3.5 Changing Thermocouple Input Type (Model CTXL-DTC)

The dual thermocouple input model CTXL-DTC can accommodate J, K, or T
thermocouple types. The factory default setting is Dual K type thermocouple
input. You can configure the recorder for other thermocouple types (J or T) from
the PC without re-calibration as follows:

Once the PC is connected to the recorder thru RS232 cable, use the following PC
commands (in Bold):

Command Description Example

IT0 Change to K Type TC IT0; Toggle Power to use new input type

IT1 Change to J Type TC IT1; Toggle Power to use new input type

IT2 Change to T Type TC IT2; Toggle Power to use new input type

After issuing the command, the response is “Toggle Power to use new input
type” which means to remove and then apply power to the recorder for the
command to take affect. At the power up, the LCD screen always shows the
thermocouple type for two seconds. This is the way to confirm thermocouple
input type.

3.6 Changing Process Voltage Input Range (Model CTXL-DPR-V)

The dual process voltage input model CTXL-DPR-V can accommodate 0-1V, 0­5V and 0-10V input range. The factory default setting is 0-5V voltage input. You
can configure the recorder for other voltage input range (0-1V, 0-10V) from the
PC without re-calibration as follows:

Wireless Temperature/Humidity
Chart Recorder

8-1

8.1 Introduction

This is our standard CTXL-TRH recorder, except that the temperature/humidity
probe is wireless. The wireless probe consists of a temperature/humidity
wireless transmitter and a wireless receiver.

The wireless transmitter has a built-in temperature/humidity sensor that
measures the air quality (Temperature & Humidity). It then transmits the data to
a wireless receiver thru an RF link. The transmitter is operated from one AA size
lithium battery and/or a DC adapter input. The transmitter also has two LED
indicators. One Green LED is for transmission indication. One Red LED is for
low battery indication as well as other wireless communication errors.

The wireless receiver plugs directly to the circular chart recorder where a
temperature/humidity probe is normally plugged into. The wireless receiver
acts as a probe, so the wireless RF link is totally transparent to the circular chart
recorder. The recorder thinks that it is directly connected to the probe. This
design allows us to offer the wireless probe as an option to all existing recorders
in the field. There is no internal upgrade required to make a standard circular
chart recorder wireless.

8.4 Error Codes

Transmitter Error Codes

The wireless transmitter uses the Red LED to provide different error information
to the user and to the wireless receiver as follows:

2 Red LED Blinks means there is an RF communication error such as Framing,
CRC, buffer overflow, etc.

3 Red LED Blinks means that the transmitter fails to communicate with the
sensor probe

4 Red LED Blinks means Low Battery indication.

The highest priority error code is 2 blinks for RF communication error. The
lowest priority error code is 4 blinks to indicate low battery. If multiple errors
occur at the same time such as bad sensor probe and low battery, the
transmitter's red LED will blink 3 times. Only when this error clears, then the
transmitter's red LED will blink 4 times to indicate the low battery.

The red LED error reporting occurs every 30 seconds regardless of the
transmission time interval.

Receiver Error Codes

The wireless receiver basically reflects all the error codes of the wireless
transmitter as follows:

1 Red LED Blink means No good message has been received from the
transmitter within 4 transmission time intervals (like 4 minutes for 1 minute
time interval), or 30 seconds minimum. The receiver will continue to search for
the transmitter’s message 10 more minutes before deciding that the transmitter
is either off, out of order, or out of range at which point the receiver will shut
itself off to conserve power.

If the wireless transmitter is back on line after 10 minutes, then the user needs to
un-plug the receiver from the recorder and plug it back in to reset the wireless
receiver.

2 Red LED Blinks means there is an RF communication error such as Framing,
CRC, buffer overflow, etc.

3 Red LED Blinks means that the transmitter fails to communicate with the
sensor probe

4 Red LED Blinks means the transmitter’s Battery is low.

The highest priority error code is 1 LED blink for No good message from the
transmitter. The lowest priority error code is 4 LED blinks to indicate
transmitter’s low battery. If multiple errors occur at the same time such as bad
sensor probe and low battery, then the receiver’s red LED will blink 3 times.
Only when this error clears at the transmitter, the receiver will then blink 4 times
to indicate the next error, if any.

The red LED error reporting occurs every 10 seconds regardless of the
transmission time interval.

Any error code except for the low battery means Probe Error for the chart
recorder.

OMEGA ENGINEERING, INC. warrants this unit to be free of defects in materials and workmanship for a
period of 25 months from date of purchase. OMEGA’s WARRANTY adds an additional one (1) month

Department will issue an Authorized Return (AR) number immediately upon phone or written request.
Upon examination by OMEGA, if the unit is found to be defective, it will be repaired or replaced at no
charge. OMEGA’s WARRANTY does not apply to defects resulting from any action of the purchaser,
including but not limited to mishandling, improper interfacing, operation outside of design limits,
improper repair, or unauthorized modification. This WARRANTY is VOID if the unit shows evidence of
having been tampered with or shows evidence of having been damaged as a result of excessive corro­sion; or current, heat, moisture or vibration; improper specification; misapplication; misuse or other
operating conditions outside of OMEGA’s control. Components in which wear is not warranted, include
but are not limited to contact points, fuses, and triacs.

herein are exclusive, and the total liability of OMEGA with respect to this order, whether
based on contract, warranty, negligence, indemnification, strict liability or otherwise, shall
not exceed the purchase price of the component upon which liability is based. In no event
shall OMEGA be liable for consequential, incidental or special damages.
