Description
The Series 5000 is designed as a fully programmable digital
temperature indicator and miniature datalogger. The displays
are 0.56" in-line red LED type. The menu driven display
prompts and 14-segment alphanumeric characters make
programming simple. Front panel programming is
accomplished through three front panel keys. Degrees F or
degrees C are indicated by a green, .4" seven segment LED
located to the right of the main display. Resolution is
selectable either 1
°
or 0.1
°
. A single dash (-) displayed at the
left of the readout indicates a negative temperature. Positive
readings are inferred (no dash displayed). Overload is
indicated by an 'OL' on the display. Plus OL (+OL) indicates
a positive over range condition or an open thermocouple.
Negative (-OL) indicates a negative over range condition.
The 5000 is powered by a 100-240Volt, 50-400Hz AC source
and uses a switching power supply for maximum input power
flexibility.
The unit will accept, depending upon the model, J,
K, E, T, R and S thermocouples or 3/4-wire 100 ohm
Platinum RTD’s, either .00385 or .00392.
Serial communications is standard RS232. This bi-
directional serial port allows the user complete program set-
up, programming and operational capability. All controls and
features are selectable through the front panel. The front
panel lens may be removed to install or remove the program
lockout jumper or adjust the analog output if necessary.
Power and serial connections to the meter are made to the
