Handheld Digital Thermometer

Operating Instructions

DESCRIPTION:

The Minco TI142 is a handheld digital thermometer designed for accurate temperature
measurement in the laboratory or field. High accuracy, normally found only in expensive bench
instruments, is achieved when the meter is used with a Minco Model S900 series handheld probe.
The meter can also interface with any 100ohm @ 0°C, Platinum RTD by using the optional AC742
binding post adaptor.

OPERATION:

1) Install a 9 volt battery in the battery compartment.

2) Insert the sensor plug into the jack on top of the meter.

3) Move the power switch to the on position.

4) Select the appropriate scaling (Fahrenheit or Celsius).
For maximum resolution and accuracy, use the °C scale.
