Section 1 - IntroductionModel RH511 is a handheld/benchtop meter that can measure & displayambient temperature, relative humidity, non-contact infrared temperature, anddual K type thermocouple temperatures.

RH511 comes with a custom backlit LCD. The LCD can display three parameterssimultaneously. It also comes with a membrane keypad to operate the unit.

RH511 has built-in wireless capability. It acts as a wireless receiver when usedwith our wireless temperature/RH transmitter, model CTXL-PT.

RH511 has a built-in laser sighting feature used as an aiming tool to measurenon-contact target temperatures. The laser beam is switchable between laser dotand circle. The laser dot indicates the center of the target temperature. The lasercircle indicates the area of the target that is being measured which is the opticalfield of view of the device.

RH511 operates from 6 AA size batteries. It also has 9Vdc adapter input and USBPC interface. The DC adapter is used for long term measurement and display.The USB port is used to configure the unit and downloading logged data.

RH511 has logging capability where the user can log all the inputs (AmbientTemperature, Relative Humidity, Thermocouple 1, Thermocouple 2, InfraredTemperature) simultaneously. The logging interval can be set from the frontkeypad and the display menus.

RH511 comes in a plastic enclosure with a rubber boot, tilt stand, and tripodmount.

Section 3 – Wireless OperationThe RH511 can communicate with our wireless temperature/RH probetransmitter model CTXL-PT series. The RH511 becomes a wireless receiver andcan receive & display temperature/RH data from the wireless probe. This optionis very helpful for applications where the probe and the meter can not bephysically connected, or the meter has to monitor multiple wireless probes.

The wireless RH511 comes in two models:RH511-W9 works with CTXL-PT-W9 915 MHz wireless probe (US & Canada)RH511-W8 works with CTXL-PT-W8 868 MHz wireless probe (Europe)

Figure 3-1 shows the general dimensions of the wireless temperature/relativehumidity transmitter (Model CTXL-PT series), labels, and descriptions.

Section 5 - Laser Sighting

You may receive harmful laser radiation exposure if you donot adhere to the following warnings:• Use of controls or adjustments or performance of procedures other than those specified here may result inhazardous radiation exposure.• Do not look at the laser beam coming out of the lens orview directly with optical instruments. Eye damage can result.• Use extreme caution when operating the laser sighting.• Never point the laser beam at a person.• Do not attempt to open the meter. There are no userserviceable parts inside.• Keep out of reach of all children.

5.1 DescriptionThe laser sighting is built into the handheld meter. It provides a visual indicationof the field of view of the thermometer. There is a laser switch in front of theinstrument. It switches between laser dot and circle when the laser beam isturned on. Figure 2-1 shows the laser warning label, the location of the laserdot/circle switch, and all the controls.

5.2 Operating the Laser SightingThe laser sighting provides a visual indication of the optical field of view of thethermometer when measuring non-contact temperatures. The followingprocedure lists all the steps necessary to measure non-contact temperaturesusing laser sighting:

• Set the target Emissivity from the display menus.

• Aim the optical lens to the target object.

• Press & hold the Laser key on the front membrane keypad. The laser beam willturn on, and the LCD display will show the laser icon. Once the laser key isreleased, the laser beam will turn off, and the laser icon will turn off from thedisplay.

Section 7 - Error CodesTransmitter Error Codes

The wireless transmitter uses the Red LED to provide different error informationto 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 thesensor probe4 Red LED Blinks means Low Battery indication.

The highest priority error code is 2 blinks for RF communication error. Thelowest priority error code is 4 blinks to indicate low battery. If multiple errorsoccur at the same time such as bad sensor probe and low battery, thetransmitter's red LED will blink 3 times. Only when this error clears, then thetransmitter's red LED will blink 4 times to indicate the low battery. The red LEDerror reporting occurs every 30 seconds regardless of the transmission timeinterval.

Receiver (Multi-meter) Error Codes

The wireless meter basically reflects all the error codes of the wireless transmitteron the display as different icons:E1 means No good message has been received from the transmitter within 4transmission time intervals (like 4 minutes for 1 minute time interval), or 30seconds minimum. The receiver will continue to search for the transmitter’smessage 10 more minutes before deciding that the transmitter is either off, out oforder, or out of range at which point the receiver will shut itself off to conservepower.

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

E2 means there is an RF communication error such as Framing,CRC, buffer overflow, etc.

E3 means that the transmitter fails to communicate with thesensor probe

E4 means the transmitter’s Battery is low.

The highest priority error code is E1 for No good message from thetransmitter. The lowest priority error code is E4 to indicate transmitter’s lowbattery.
