1 - INSTRUMENT DESCRIPTION
1.1 - GENERAL DESCRIPTION
TLV 38 is a digital microprocessor-based indicator.
Depending on the model required the input accept:
C: Thermocouples temperature probes (J,K,S and TECNOLOGIC
IRS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV),
Thermoresistances PT100.
E : Thermocouples temperature probes (J,K,S and TECNOLOGIC
IRS Infrared sensors), mV signals (0..50/60 mV, 12..60 mV),
Thermistors PTC and NTC.
I : normalized analogue signals 0/4..20 mA
V : normalized analogue signals 0..1 V, 0/1..5 V, 0/2..10 V
The instrument can have up to 2 outputs: relay type or can drive
solid state relays type (SSR).
The process value is visualized on 4 red displays, while the output
status is indicated by 2 LED displays.
Other important available functions are:
maximum end minimum peak memory, Hold function, zero
calibration (resetting) function and/or auto-ranging for normalized
signals, parameters protection on different levels.

1 - Key P : This is used to access the programming parameters
and to confirm selection.
2 - Key DOWN : This is used to decrease the values to be set and
to select the parameters. If the key is held down, the user returns to
the previous programming level until he exits the programming
mode. Outside the programming mode it permits visualisation of
the minimum peak measure.
