MODEL HH801A

DUAL J/K INPUT

DIGITAL THERMOMETER

INTRODUCTION

This instrument is a portable 31/2 digit, compact-sized digital thermometer designed to use external K type and J type thermocouples. It also has the feature that sensor offset can be adjusted for in the field. There are 2 inputs for miniature thermocouple connectors at the top of the instrument marked T1 and T2.

SAFETY INFORMATION

It is recommended that you read the safety and operation instructions before using the thermometer.

WARNING

Accuracy:

Accuracy is specified for operating temperatures over the range of 18°C to 28°C (64°F to 82°F), for 1 year, not in- cluding thermocouple error.

Temperature Coefficient:

0.1 times the applicable accuracy specification per °C

from 0°C to 18°C and 28°C to 50°C (32°F to 64°F and

To prevent accidental loss of MAX, MIN and MAX-MIN, this mode can only be cancelled by pressing and holding down the “MAX MIN” button for 2 seconds to exit and clear readings.

7.“CLR/READ“ Button

Press “READ” button to enter READ Mode, the “READ” annunciator is displayed in the upper right corner. Press “”or “” button to review the recorded data. The LCD automatically alternates between the data and index. Press the “CLR” button and hold down for 2 seconds to clear the memory.

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.

CAUTION

Repeated sharp flexing can break the thermocouple leads. To prolong lead life, avoid sharp bends in the leads, especially near the connector.

1. “” Power Button

Press the “” button to turn on or off thermometer.

2. “/°C/°F” Button

Readings are 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 thermometerwas last turned off. To change the tem- perature scale, press the “°C/°F” button.

3. “/” Button

Press the“”button to trigger the on backlight. Press the “” button again to make the backlight brighter and press “” button once more to turn off the backlight.

Backlight on →Brighter → Backlight off.

4. “ADJ/HOLD” Button

Press the “HOLD” button to enter the Data Hold mode, the “HOLD” annunciator is displayed at the top of the display. When HOLD mode is selected, the thermometer holds the present readings and stops all further measurements.

Pressing the “HOLD” button again cancels HOLD mode, causing the thermometer to resume measurement.

5. “APO/TYPE“ Button

Press “TYPE” button to select the type of thermo couple “K” or “J”. Make sure the proper type has been selected. Pressing and holding down “APO” button for 2 seconds

Up 125 data points can be recorded into memory.

Press “REC” button once to record each data point. When the data is recorded, “REC” is displayed in the upper right corner. If the memory is full, data will not be recorded into the memory and “REC” will not be displayed. Data can be recorded again after the memory is cleared.

9.“T1 T2/T1-T2/ “ Button

Press “T1”, “T2”, “T1-T2” button to select input mode T1, T2 or T1-T2. The input selection indicates which input is selected for display, T1 thermocouple, T2 thermocouple or the differential between the two thermocouples (T1-T2).

1.Insert the thermocouple into a known temperature (T) until the display stabilizes near the known temperature

(T). example: ice point at 0°C or boiling water 100°C 2.Press and hold the “ADJ/HOLD” button for 2 seconds until the display starts to blink.

3. Press ” or “ ” to adjust the displayed value.

4.It can be adjusted ±6°F (±3°C) from default. If you can not adjust your reading to match the known tem- perature (T), please check your T/C type. The meter may require calibration.

5.Press “ENTER” button to confirm.

WARNING

To avoid possible electrical shock, disconnect the ther- mocouple connectors from the thermometer before removing the cover.
