INTRODUCTION

This instrument is a 5 digit, compact-sized portable digital thermometer designed to use external K-type and J type thermocouples as temperature sensor. Temperature indication follows Reference Temperature/Voltage Ta- bles (N.I.S.T. Monograph 175 Revised to ITS-90) for K- type and J-type thermocouples. Two K-type thermocou- ple are supplied with the thermometer.

SAFETY INFORMATION

It is recommended that you read the safety and opera- tion 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.

FEDERAL COMMUNICATIONS

COMMISSION

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two condi- tions:(1) this device may not cause harmful interfer- ence, and (2) this device must accept any interference received, including interference that may cause unde- sired operation.

NOTE

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection. This equipment gener- ates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the in- structions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference to ra- dio or television reception, which can be determined by turning the equipment off and on, the user is en- couraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit dif- ferent from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV tech- nician for help.

Shielded interface cables must be used in order to comply with emission limits.

Changes or modifications not expressly approved by

the party responsible for compliance could void user‘s authority to operate the equipment.

WIRELESS NOTE

Wireless receiver must keep a distance at least 40cm from the meter and meter to meter must keep a dis tance at least 30cm.
