WARNING  
To avoid electrical shock, do not use this instrument when working  
voltages at the measurement surface over 24V AC or DC.  
WARNING  
To avoid damage or burns, do not make temperature  
measurement in microwave ovens.  
The  
symbol on the instrument indicates that the operator must refer to an  
explanation in this manual.

OPERATING INSTRUCTIONS  
Power Switch  
The key turns the thermometer on or off. In the data SET mode, can not  
power off, must leave data SET mode then power off.  
1
2 °C/°F Selecting the Temperature Scale (Main display)  
Reading the main displayed in either degrees Celsius(°C) or degrees  
Fahrenheit(°F). When the thermometer is turned on, it is set to the  
temperature scale that was in use when the thermometer was last turned  
off. To change the temperature scale, press the °C/°F key.  
3
HOLD Mode (only Main display)  
Pressing the HOLD key to enter the Data Hold mode, the  
"HOLD" annunciator is displayed. When HOLD mode is selected, the  
thermometer held the present readings and stops all further measure-  
ments.  
Pressing the HOLD key again to cancel HOLD mode causing thermometer  
to resume taking measurements.  
In the MIN/MAX recording mode, press HOLD key to stop the recording.  
Press HOLD key again to resume recording. (Previously recorded reading  
are not erased).

5 Pt385/Pt3926 T1 Input RTD Probe Select  
The Pt385/Pt3926 key switch the T1 input selects the Pt385 or Pt3926 RTD  
probe as input.  
When the thermometer is turned on, it is set to the probe selected that was  
in use when the thermometer was last turned off.  
MIN MAX with Time record Mode  
6
Press MIN MAX key to enter the MIN MAX Recording mode, (displays the  
Maximum reading with time, Minimum reading with time and Average  
reading stored in record mode). In the this mode the automatic power-off  
feature is disabled and  
key, °C/°F key, REL key, SET key, Hi/Lo LIMITS  
key, Pt385/Pt3926 and all RECALL keys are disabled.  
The beeper emits a tone when a new minimum or maximum value is  
recorded.  
Present temperature reading displayed on second display.  
Push MIN MAX key to cycle through the MAX, MIN and AVG readings.  
If an overload is recorded, the averaging function is stopped and average  
value display"----.-".  
The true average of all the reading taken over at least 22 hours preiod can  
be displayed. If 22 hours is exceeded, new averages are no longer  
calculated. Thelastcalcalatedvalueisretainedastheaveragereading, but  
the actual minimum and maximum reading will continue to be captured.  
In the this mode, press HOLD key to stop the recording of readings, all  
values are frozen, press again to restart recording.

displayed. Present temperature reading displayed on second display.  
Press REL key again to exit the relative mode.  
The relative value can also be entered by the user. (See "SET mode" later  
in this manual.)  
When the desired Relative value has been entered, press REL key to enter  
the Relative mode, press SET key use set Relative value as a reference  
value. Press REL key again to exit the relative mode.  
In the Relative mode, the value (can not >±3000.0 counts) shown on the  
LCD is always the difference between the stored reference and the present  
reading.

HH 504 / HH 505 CALIBRATION PROCEDURE  
Note: The following calibration procedure should perform only by qualified technicians  
who have access to the items as following.  
Equipment: The class of calibrator had better 10 times greater than the measured meter.  
1. Turn off the meter then set the adjusted jumper to J1.  
2. Insert the 383.00Ω calibrator to the T1 then turn on the meter, the main  
display reading reads 1830.0 then press " ENTER " key.  
3. The second display is stabilized (about 5sec.), then press " ENTER " key  
when the meter auto power off then set the jumper back to J3 position.  
4. Turn on the meter then Insert the 100.00Ω calibrator. The display reading  
reads 0°C if the calibration procedure is right.
