UNPACKING AND INSPECTION

Your shipping carton should include:

1 TMD-10 temperature meter

2 K-type thermocouples

1 9 volt battery

1 Manual

If any of the items are damaged or missing, return the complete package to

the place of purchase for an exchange.

INTRODUCTION

The TMD-10 is a dual input temperature measurement meter using Type K or

Type J thermocouples.

OPERATION

Press the1. button to turn power on or off

Set the Function Switch to °C or °F.2.

Select thermocouple type (K / J) and connect the thermocouple(s) to the3.

T1 or T2 input.

Do not mix thermocouple types.

Match the polarity of the adapter to the polarity of the thermocouple

input.

Expose the thermocouple(s) to the temperature(s) to be measured.4.

Read the LCD display.5.

°C / °F

Press the key to change from Celsius (°C) to Fahrenheit (°F) temperature

scale.

This setting can not be changed when in the HOLD mode. The TMD-10 will

auto save the temperature scale setting during shutdown.

MAX, MIN and AVG

Press the button to start the recording of the maximum, minimum,

and average of all readings after the function is enabled. Pressing the

button steps the top reading through the MAX, MIN, and AVG values. Press

the button for > 1 second to disable the function.

The MAX, MIN or AVG reading is shown on the top display and the actual

reading is shown on the bottom display for T1.

To use MAX, MIN, and AVG for T2, disable MAX, MIN, and AVG and press and

hold key > 1 sec to swap T2 to the top display and T1 to bottom display.

Press button again to activate the function.

If the TMD-10 turns off because of Auto Power Off, the recorded values will

be saved for use when the meter is re-energized.

K / J

Press key to switch T1 from type K to type J thermocouple for the top

display.

Press and hold key > 1 sec to swap T2 to the top display and T1 to

bottom display.

Press key to switch T2 from type K to type J.

Press and hold key > 1 sec to swap T1 to the top display and T2 to

bottom display.

This setting cannot be changed if in HOLD, MAX/MIN, T1-T2 or REL

modes.

The TMD-10 will auto save the thermocouple type setting during shutdown.

HOLD

Press the key to freeze the LCD displays. Press the HOLD key again to

return to normal operation. When the function is enabled, all function

keys are disabled except for power key.

REL

Relative mode allows the user to offset the subsequent meter measurements

with the top display reading as the reference value.

Press the button to enable the Relative function for the T1 thermo-

couple. The top display will reset to 0.0 (reference value) and subsequently

readings display the difference between the reference value and the actual

reading. The actual reading is shown on the bottom display. Press the

button to disable the Relative function.

To use the Relative mode for T2, disable and press and hold key

> 1 second to swap T2 to the top display and T1 to bottom display.

T1 T2 / T1-T2

T1 T2 displays the 2 inputs independently. Press and hold button > 1

second to swap display location of the display location of T1 and T2.

(T1-T2)

Press button to display T1 minus T2 temperature value. The top display

shows the T1-T2 temperature. The lower display shows the top display

selected in the T1 T2 mode. Press button again to disable this function

Auto Power Off (APO)

The TMD-10 powers down automatically after approximately 15 minutes of

inactivity to save battery life. Press the button to turn the TMD-10 ON. You

can disable Auto Power Off by pressing the button > 1 second after the

TMD-10 is ON.

The power cannot be turned OFF in the OFFSET SETUP mode.

Thermocouple Error Correction (OFS, Offset)

User can add an offset to compensate for the error of speciﬁc thermocouple

probes.

Press and hold the1. (OFS) button > 1 second to enter the Offset Setup

mode.

Immerse the thermocouple(s) in thermos bath with crushed ice and fresh2.

water (0.0 °C / 32.0 °F).

Press the3. button to increase or power button to decrease the

Offset value. The allowable adjustment range is ± 5 °C / ± 9 °F in 0.1°C/°F

increments.

Press4. (SET) button to save and leave setup mode. The “Offset” icon

will remain on the LCD.

Press and hold5. button > 1 second to swap T2 to the top display and

T1 to bottom display. Press button to switch T2 from type K to type J.

Repeat steps 1, 2, 3 and 4 for T2.6.

To remove the Offset, Repeat steps 1, 2, 3 and 4 setting the offset (lower7.

display) to 0.0. When both thermocouple offset are zeroed out, the

“Offset” icon will be turned off.
