1. Introduction

The HH1385 is a digital 4 input thermometer and data logger that works with any K, J, E, T,
R, S, N type thermocouple temperature sensors. This unit offers higher accuracy and better
uniformity across various thermocouple types. This device measures/stores over 16,800
temperature readings and allows up to 4 thermocouple connections that plug into a miniature
female thermocouple receptacle at the base of the unit.
The user can easily set up the initial data logging parameters including thermocouple type,
logging Intervals, high/low alarm settings, and desired temperature units (°C,°F or °K). The
user may also download the stored data by plugging the meter straight into a PC’s USB port
and running the easy-to-use Windows software.

5. Operation

Power on or off

Press button，turn on or turn off.

Turn on backlight

Press button to turn on or turn off the backlight.

＊The backlight will automatically turn off after being lit for 15 seconds.

Alarm on or off

Press to turn “on” or “off” the alarm, followed by "LIMIT" appears on the LCD.

This LCD shows the status "on" or "off" of the alarm function. It is possible to set the upper
and lower limit of the temperature range by yourself. When the temperature reading
exceeds the range, the buzzer will alarm until the temperature back to the range or the
alarm function turned off.
(For the limit range setup, please enter Setup Function)

Auto Recording

Press and hold for ≥ 2 seconds to enable or disable the auto-recording function "LOG"
The LCD display will first show the number of logs for REC/MEM START mode and then
switch back to temperature mode after 1 second.

The auto-recording is such if the current number is 3, it will be increased to X by 1 at each
pressing. (the number of logs in HH1385 is up to 16800)
* Execute "LOG" to disable the auto-shutdown function. For recording for a long time,
please connect the meter to an external power supply.

Thermocouple Type Selection (TYPE):

Press to enable selection of different thermocouple types in a full cycle.

Manual Record

Press , followed by "REC" appears on the LCD, the log number of records will increase

by +1 at each time, and one log will be recorded.

The manual records are up to 200 logs.

Unit Switch for °C, °F and °K

Press and hold for ≥ 2 seconds to switch the unit: Celsius (°C), Fahrenheit (°F), or Kelvin

(°K).

Data Hold

Press to enable or disable the data hold function.

Disable Auto Power Off Function

Press and hold for 2 seconds to enable or disable the auto power off function.

Relative Value Measurement

Press to enter the relative:
Just use one thermocouple, the difference between the two temperatures can be measured.
For example, measure the first temperature as 25°C, and then press to show 0°C on

the LCD. Again, measure the second temperature. If the second temperature is measured
as 30°C, the LCD will show the difference value 5°C (30-25=5°C).

Again, press to disable the function.

The left shows the relative value, right shows the temperature value being measured.

Press the / and hold to switch the display between "T1 & T2" and "T3 & T4".

Offset Value

The user can set the offset value to compensate for the error due to the working

thermocouple wire.
Press and hold for ≥ 2 seconds to set the offset value in OFFSET mode.
Press or to increase or decrease the offset value by the scale of 0.1°C, °F, or °K.

The setting range is ±5°C, ±5K, or ±9°F.
*If to set offset value of another channels, press and to switch and select between

"T1 & T2" and "T3 & T4" for adjustment.
Press to save the setting value and exit the setting mode.
*If the value updated to be 0.1, "OFFSET" will continuously appear on the LCD. "OFFSET"

will not disappear unless it is corrected back to 0.0.

Press to enable or disable T1 – T2 .

The value shown on the left shows the difference of T1 – T2, and the one shown on the
right is the T1 value which is measured presently.

Press and hold for ≥ 2 seconds for the position change of T1 and T2.

Change Display of T3-T4 vs. T3 & T4

Press to show the value of T3 - T4.

Again, press to disable the function.

MEM CALL.

Press or to read the previous or next record.

The three items of time, number of logs and temperature data are displayed on the LCD

and are auto-displayed cyclic by second.

It is used in the "MEM CALL" mode. Press to exit this mode.

Maximum /Minimum/ Average Value

Press repeatedly to select maximum, minimum and average value of measured

data.

When MAX, MIN, and AVG are displayed at the same time, it represents the elapsed

time of the measurement, and the present temperature T1 / T3.

Setup

Press and hold for ≥ 2 seconds for SETUP
