This display shows the wireless transmission interval.
It can be set to 2, 10, 30, 60, 120 seconds using the Up and
Down arrow keys.

20

This display shows the unit ID address. It can set from

Enable Data Logging
You initiate logging data (Relative Humidity, Ambient
temperature, Infrared temperature, Thermocouple 1,
Thermocouple 2) by pressing the SET/REC key from the
following display menus: RH/Temp/IR (Main Menu)
RH/TC1/IR
RH/TC1/TC2
RH/TC1-TC2/IR
RH/Temp/TC2

The LOG display icon will turn on. The unit will log the
five sets of data until the internal memory gets full. It will
then stop logging data. The LOG display icon will blink
accompanied by a one-time 3 beep warning. You can also
stop logging data at any time by pressing the SET/REC
key again.

Infrared Function

You can set the target emissivity from screen

6

(from
Display Screens Explained Section). Simply aim the
infrared lens to the target object, press and hold the laser
button to turn on the laser beam. The laser beam indicates
either the center of the target object (Laser Dot) or the area
of the target being measured (Laser Circle). There is a 5/8
inch offset between the center of the optical field of view
and the laser beam. It may take a few moments for the IR
reading to stabilize.

Operation

In order to install the 6 AA size batteries, remove the
yellow rubber boot, and unscrew the battery door with
the case to get to the battery compartment.

After installing the batteries, close the battery door, and
put back on the rubber boot. If the unit comes with a
wired temperature/RH probe, connect the probe to the
meter. The connection is at the bottom of the unit. The
probe can be attached to the meter via the probe holder
on the side.

Press the Power button

to turn on the unit. The
display will show the relative humidity, ambient
temperature, and the no-contact infrared temperature.

Using This Quick Start Manual

Use this Quick Start Manual with your RH511
handheld/benchtop meter for quick setup and
basic operation. For detailed information, refer to
the User’s Guide (Manual # M4954).

General Information

The RH511 is a handheld/benchtop meter that can
measure & display ambient temperature, relative
humidity, non-contact infrared temperature,
and dual K type thermocouple temperatures.
RH511 has built-in wireless capability. It acts as
a wireless receiver when used with our wireless
temperature/RH transmitter, model CTXL-PT.

RH511 has a built-in laser sighting feature used
as an aiming tool to measure non-contact target
temperatures. The laser beam is switchable
between laser dot and circle. RH511 operates from
6 AA size batteries. It also has 9Vdc adapter input
and USB PC interface. 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 (Ambient Temperature, Relative
Humidity, Thermocouple 1, Thermocouple 2, and
Infrared Temperature) simultaneously. The logging
interval can be set from the front keypad and the
display menus.

This is the main display screen when you power
up the unit. It displays the relative humidity (%RH),
ambient temperature (°F) on the second line, and
the non-contact infrared temperature (°F) on the
third line of the display. The IR-T icon indicates IR
temperature measurement. Press and holding the
laser key will turn on the laser beam and the laser
icon on the display. There is a laser cover switch
on front of the unit where by turning the cover, the
laser beam changes from circle to laser dot.
