MINCO MODEL TI142
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.

Condition
Causes
Remedy
Display shows "1"
continuously in only the
leftmost digit.
RTD is open.
Disconnect from meter,
ohm RTD continuity and
connections. Replace the
RTD if faulty.
Over range temperature.
Switch to °F scale.
System is only accurate to
400°F, but meter will read
to 600°F.
Reading shows "-1"
continuously in only the
leftmost digit.
The RTD is shorted.
Disconnect from meter,
ohm RTD continuity and
connections. Replace the
RTD if faulty.
" " or "LO BAT" reading in
upper left corner of LCD
display.
Battery is worn out.
Replace battery.
Poor battery connections.
Clean connections.
LCD display shows
nothing.
Dead or missing battery.
Replace battery.
Display shows very unlikely
temperature.
Wrong scale setting.
Move switch on front panel
to appropriate position.
(Fahrenheit or Celsius).
Faulty RTD.
Ohm the RTD connections.
Replace if faulty.
Wrong Element type. (e.g.
The PD in S902PD60 must
match the meter's code
TI142PD.)
Use correct RTD. Meter's
code is listed inside battery
compartment.
