KTD-02

7. Normal Psychrometer Mode

• Turn the Meter ON by pressing the button
until NORM is displayed in the LCD.
• Press "SENSOR" button and holding for 2s to select temperature sensor: T/C for
thermocouple, NTC for sensors in the "cage".
• For T/C, the display will show the temperature . For NTC, press "SENSOR" button to
select RH,DP,WB,DB mode and the desired icon (RH,DP,WB,DB) is displayed. Then read the
display.

8. Target Superheat Mode(TSH)

• Turn the Meter ON by pressing the button
until TSH is displayed in the LCD.
Note: blinking numbers mean you are seeing real-time measurements.
Non-blinking mean the reading has been "locked in". Press ENTER button to unlock and
take a new reading.
• The more accurate method:
a. Wet the thermocouple A.Clip it to the front of the evaporator coil.
Plug it into the top of the meter. Make sure the display show ID and WB. If not, press
"SENSOR" button. Press and holding "SENSOR" button until T/C is displayed. Once the
reading is stable, press ENTER button.
b. Unplug the thermocouple A and plug in the thermocouple B.
c. Clip the thermocouple B to the side of the condenser. Press "SENSOR" button until OD
and DB are displayed. Once reading is stable, press ENTER.
Note: for DB, you can put the "cage" sensors in front of the condenser and select NTC if
that is easier.
The easy way: While the numbers are blinking, press and holding "SENSOR" button
until NTC is displayed. Press "SENSOR" button until WB or DB is displayed. When WB is
displayed, place the "cage" sensors in front of the indoor return and press ENTER button
once reading is stable. When DB is displayed, put the "cage" sensors in front of the
condenser and press ENTER button when the reading is stable.
• Press OUTPUT button to display Target Superheat.
• Compare Target Superheat to Actual Superheat.

• Adjust refrigerant levels accordingly for a fixed restrictor system.
If Actual Superheat is higher than Target Superheat, add refrigerant.
If Actual Superheat is lower than Target Superheat, recover refrigerant.

9. Target Evaporator Exit Temperature (TEET)

• Turn the Meter ON by pressing the button
until TEET is displayed in the LCD.
Note: blinking numbers mean you are seeing real-time measurements.
Non-blinking mean the reading has been "locked in". Press ENTER button to unlock and
take a new reading.
• Wet the thermocouple A wet sock thermocouple and clip both thermocouples
(thermocouple A and thermocouple B) in front of the evaporator.
• Plug the thermocouple A into the top of the SRH2.
Note: If "OL" is displayed, then the measurements are out of range.
Retake the temperature measurements and ensure the temperature inputs are correct.
• Press "SENSOR" button until WB is displayed. Press and holding "SENSOR" button until
T/C is displayed. When reading is stable, press ENTER button.
• Unplug the thermocouple A and plug in the thermocouple B.
• Press "SENSOR" button until DB is displayed. Press and holding "SENSOR" button until
T/C is displayed. When reading is stable, press ENTER button.
• Press OUTPUT button and read Target Evaporator Exit Temperature.
Note: If "OL" is displayed, then the measurements are out of range.
Retake the temperature measurements and ensure the temperature inputs are correct.
• Compare Target Evaporator Exit Temperature to Actual Evaporator Exit Temperature. The
Actual Evaporator Exit Temperature is the measured temperature of the air after it has
passed through the evaporator.
