Basic Measurement Display
Display varies depending upon the input module connected.
Temperature (Thermocouple / Pt100 / Pt1000)
Temperature measurement (Unit: °F / °C) will be
displayed. Sensor type will be displayed under the
measurement; the factory default setting is Type K
and Pt (Pt100). The sensor type setting can be
changed in the Remote Unit Settings of the
application.
Voltage
Voltage measurement (Unit: V / mV) will be displayed.
Due to the wide measurement range, the device has
been set by default to adjust the decimal point
automatically to display the measurement in V. The
unit of display can be changed in the Remote Unit
Settings of the application.
4-20mA
4-20mA measurement (Unit: mA) will be displayed.
Pulse
There are two display methods for the pulse measurement. The display
method can be changed in the Remote Unit Settings of the application.
Pulse Rate (Max: 61439)
The most recent pulse count (Unit: P) for the recording
interval period will be displayed. The display will be
refreshed every one-sixtieth of the recording interval
(at minimum of every one second). 50,500 pulse count
will be displayed as [50.50P] with “K“below the
measurement value. The display is in units of 10 pulses.
Total Pulse Count
The cumulative number of pulses (Unit: P) will be
displayed from 0 to 9999. The displayed count will be
refreshed every one second, and upon exceeding
9999, the count will start over again from 0.
How to Read the LCD Display
[REC] Mark Shows the recording status.
ON: Recording in progress
BLINKING: Waiting for programmed start
OFF: Recording stopped
[ONETIME] Mark Shows the recording mode.

Battery Warning
Mark Indicates it is time for the battery to be replaced.
Measurement and
Message Area
Measurements or operational messages are shown
here.
Sensor Type
The type of sensor connected to or set in the logger is
shown here.
Thermocouple: Type K, J, T, S
Platinum Thermal Resistance Sensor: Pt (Pt100), PtK
(Pt1000)
[Ir] Mark
Indicates that the logger (Remote Unit) has not been
registered to the Base Unit or the wireless communi-
cation is stopped (inactive radio).
[COM] Mark
Indicates that the device is in Bluetooth communication.
Unit of Measure-
ment Shows the unit of measurement.
• When being used in very hot or cold environments the display may become dicult to
read. This is not a malfunction.

*1: Measurement item depends on the input module (sold separately).
*2: Only “Endless” is available when using the RTR500BW, RTR500BM, RTR-500NW/AW or
RTR-500MBS-A
as a Base Unit.
*3: Bluetooth is available when using the RTR500BW as a Base Unit and making device
settings in the mobile app (T&D 500B Utility).
*4: When using RTR-500B1 it is necessary to purchase Lithium Battery (LS26500). For
details, contact your local authorized distributor.
*5: Battery life depends on several factors, including ambient temperature, radio
environment, frequency of communication, recording interval, and quality of the
battery being used. All estimates are based on operations carried out with a new
battery and are in no way a guarantee of actual battery life.
*6: Input module (sold separately) is not water resistant.

Other Indications on Display
Logging Capacity FULL
When Recording Mode has been set to “One Time” and
the logger reaches its logging capacity of 16,000 readings,
recording will automatically stop and in the LCD the
measurement and the word [FULL] will alternately appear.
Estimation of time until [FULL] is displayed
Rec Interval 1 second 30 seconds 1 minute 10 minutes 60 minutes
Time Period About 4

Data Transmission via Wireless Communication
The measurement and the word [SEnd] will alternately
appear when data is being sent via wireless communica-
tion to the Base Unit. Recording will continue during
wireless transmission.
Input Module Unrecognized (factory default)
This will appear if, after purchasing, the input module has
never been connected to the logger. (No unit displayed)
Input Module Unconnected or Damaged
This will appear if the device cannot conrm a connection
with the input module after having recognized it. (Unit of
Measurement displayed)
• If nothing is displayed after reconnecting the module to the device, there is a possibility
that the module or the device has been damaged.
Sensor Unconnected or Damaged
This will be displayed when a sensor has not been
connected to the module or the wire has been broken.
Recording is in progress and so is battery consumption.
• If nothing appears on display after reconnecting the sensor to the device, there is a
possibility that the sensor or the device has been damaged.
Measurement Range Exceeded
[OL] will appear if a measurement exceeds the measure-
ment range.
Display Range Exceeded
When measuring voltage in mV range, the measurement
in the LCD display will ash if it exceeds the display range
of the device.
