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 Ta­bles (N.I.S.T. Monograph 175 Revised to ITS-90) for K­type and J-type thermocouples. Two K-type thermocou­ple are supplied with the thermometer.

SAFETY INFORMATION

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

To avoid electrical shock, do not use this instrument

when working voltages at the measurement surface

To avoid damage or burns, do not make temperature

measurement in microwave ovens.

Repeated sharp flexing can break the thermocouple

leads. To prolong lead life, avoid sharp bends in the

leads, especially near the connector.

FEDERAL COMMUNICATIONS

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

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 gener­ates, uses and can radiated radio frequency energy and,
if not installed and used in accordance with the in­structions, 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 ra­dio or television reception, which can be determined
by turning the equipment off and on, the user is en­couraged 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 dif­ferent from that to which the receiver is connected.

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

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

Changes or modifications not expressly approved by

recording. Press key again to resume recording.

(Previously recorded readings are not erased).

Backlight function mode

Press the button for more than two seconds to turn
on the backlight Press the button again for more than two
seconds to turn off the backlight. The backlight will
switch-off automatically after 30 seconds.

4. T1 T2/T1-T2 Main display Input Selection

The input selection indicates which input is selected for
main display; T1 thermocouple, T2 thermocouple or the
difference between the two thermocouples (T1-T2), when
the thermometer is turned on, it is set to T1.
