4. Preparations Before Taking Measurements
4.1. How to Install the Batteries
Make sure to turn the power off when replacing batteries.
Note: To maintain the waterproofing performance, firmly tighten the screws on
the battery cover.
Applicable models: HR-11*0/HR-12*0
4.2. How to Use the Hand Strap
Place the enclosed hand strap on your wrist to prevent the instrument from
dropping.
Loop the thin cord of the strap through the hole and then pull the other end of
the hand strap through that loop.
(1) Loosen both
screws and
open the cover
of the battery
housing.
(2) Pay attention
to the
orientation of
the batteries.
(3) Install the
batteries.
(4) Reattach the battery
housing cover, tighten
both screws, and then
press the edge of the
cover to secure it.

Note: The AC adaptor is available as an option. Please use one as
specified by Anritsu Meter.

6
4.4. How to Set the Probe
Set the probe to the main unit as shown in the illustration below. It is designed
so that if the probe orientation is incorrect, it cannot be fully inserted. If the
probe is forcefully inserted, failure may result. Please check the probe’s
orientation before inserting it.
[HR-1*00] [HR-1*50]
4.5. How to Use the Soft Case
To protect the instrument from dirt or scratches, etc., use the attached soft
case.
When using an AC adaptor, alarm output, and/or analog output, open a hole at
the relevant position on the soft case by using scissors or a similar object.

5.1. Power ON/OFF
Pressing the POWER key will illuminate all the indicators for about three
seconds and start the measurements.
Press the POWER key again to turn the instrument off.

5.3. Automatic Power OFF Function
When the AUTO OFF key is pressed, “AUTO OFF” symbol will illuminate on the
screen. If no key operation is performed for a certain period of time (about five
minutes), the power will automatically be turned off, preventing the unit from
remaining turned on. To release the Automatic Power OFF function, press the
AUTO OFF key again.

Press the RESO key to switch the resolution.
 0.1°C resolution indication: A range between -104.9
and 504.9°C is displayed with a 0.1°C resolution. If a
temperature is out of this range, the instrument will
automatically indicate it at a 1°C resolution.
 1°C resolution indication: The 1°C resolution is
applied to all temperatures.

5.7. Calibration Function [Applicable Model: HR-13*0]
The calibration function offsets-compensates the measured data.
(1) Calibration settings
(i) Make the probe contact the object of measurement, and when the
indication becomes stable, press the CAL SET key.
Note: When the CAL SET key is pressed, the calibrated temperature
first shown is a value that is calculated by adding the offset value that
was set last time to the current temperature.
In the above case, the last offset value is +0.4°C.
(ii) Use the ˄ and ˅ keys to set up a calibration value (sub-screens) to a
desired temperature.
Note: The setting range with the ˄ and ˅ keys are limited within
±10°C of measured values.
(iii) Press the ENTER key to complete the setting and automatically
return to the calibration mode.
Pressing the CAL SET key before pressing the ENTER key will
interrupt the setup process and the normal mode will resume.
(2) Calibration mode
During calibration mode, “CAL” is displayed on the
screen. In the main display, a value calculated by
adding the offset value to the current temperature is
displayed.
In the case of the image on the left, the current
temperature is 199.6°C, and the offset value is +0.4°C.

12
(3) Releasing the calibration mode
To release the calibration mode, press the CAL SET key
twice.
5.8. Alarm Function [Applicable Model: HR-13*0]
The alarm function indicates data abnormalities when
measured data go out of the setup range (upper and
lower limits.) For every measurement, the alarm
function is turned on. When an abnormality is
detected, a mark to indicate the abnormality is shown
at the top of the screen.
Measured data status Mark indicating abnormality
Upper limit ≤ Measured data ALM ↑
Lower limit ≥ Measured data ALM ↓
Within upper/lower limits of
alarm None
(1) Setting of upper/lower limits of alarm
(i) When the ALM SET key is pressed, the setting
screens are switched in order as follows. Display the
desired screen to make changes.

(ii) Change the numerical value with the ˄ and ˅
keys. Press and hold the ˄ and ˅ keys to increase the
rate of change by 10 and 100 times.
(iii) Press the ENTER key to make new settings
effective. If the ALM SET key is pressed before
pressing the ENTER key, new setups are canceled.
(2) Turning buzzer sound ON/OFF
When the key is pressed, “ALM” and will illuminate on the
screen. When abnormal data is detected, the buzzer sound is outputted.
