CL3515R K/J/T/E/R/S/N/L/U/B/C Calibrator Thermometer

INTRODUCTION

This instrument is a 4 1/2 digit, compact-sized portable digital calibrator thermometer
designed to use external K/J/T/E/R/S/N/L/U/B/C type thermocouples as temperature
sensor. The thermometer features a dual thermocouple input, an adjustable T/C offset.
The thermocouples types comply with the (N.I.S.T. Monograph 175 Revised to ITS 90
standard).

SAFETY INFORMATION

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

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.

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 “ ”

The “

” button turns the thermometer on or off. When entering REC mode, the

power off function is disabled.

Remark: The meter will run self calibration when the meter starts.

The measuring leads and calibration wires must be removed before
taking measurements, and you can get accurate calibration values.

2. Button “°C/°F/°K”

Press the °C/°F/°K button to cycle through temperature scale, °C, °F and °K.

3. Type Selection (thermocouples)

Press the “type” button and the selected symbol will blink which means in the setting
mode.
Press “” button to make right shifts to cycle through

K→J→T→E→R→S→N→L→U→B→C→mV.

Press “” button to make left shifts to cycle through

K→mV→C→B→U→L→N→S→R→E→T→J.

Press the “type” button again to choose the selected thermocouple.

4. Backlight “

Pressing the button less than two seconds to turn on and pressing the button again less
than two seconds to turn off the backlight in the LCD. It will turn off after thirty
minutes without operation.

It is in the APO mode when the meter is turned on and will turn off the meter without
operation for fifteen minutes. Pressing the “ ” button over two seconds to cancel the
function. And pressing the “

5. “REL” button

The relative value function can be used for comparing the saved reference value with
other measurements. Press the “REL” button less than to store the current
measurement as the reference value, and press the “REL” over two seconds to disable
the function.

6. “HOLD” button

When HOLD mode is selected, the thermometer holds the present readings and stops
all further measurements. To activate the data hold mode, press the HOLD button,
and “HOLD” is displayed on the LCD. Pressing the HOLD button again cancels the

MAINTENANCE

Battery Replacement

Power is supplied by a 9 volt battery. (NEDA 1604, IEC 6F22). The “ ” appears on
the LCD display when replacement is needed. To replace the battery, remove the two
screws from the back of the meter and lift off the battery cover. Remove the battery
from battery contacts.

Cleaning
