Texmate TM Series Operating

˚C or ˚F, 5V DC powered with screw terminal or edge connector inputs.

General Features

Texmate's popular TM-35 Series of 5V DC powered temperature
meters are available with an LED or LCD display.
The meters are supplied factory-configured either for 'J' or 'K'
thermocouples, and scaled for ˚C or ˚F. On site re-scaling for ˚C
or ˚F is possible. A selectable ˚C/˚F descriptor is included with
every meter. The unique differential input configuration facili-
tates operation with both grounded and ungrounded probes and
allows several meters, operating with grounded thermocouples,
to be powered by the same non-isolated 5VDC supply.
The standard meter is provided with TB-KIT screw terminal
blocks and insulated quick- disconnects. For the greatest con-
venience and ease of use, order the optional preconfigured
Push-On screw terminal connectors. (see Push-On Screw
Terminals and Ordering Information on pages 3 & 4)
Typical Application Connections
Single-Ended Input
For optimum noise
reduction, either the
+ or - lead of the
thermocouple should
be connected to
power supply ground.
Differential Input with Grounded Thermocouples
The unique differen-
tial input of the TM-
35 Series enables
the use of grounded
thermocouples by
several meters pow-
ered from the same
5V DC supply.
