Operation Manual

ANALOG OUTPUT – The unit may be ordered with a DC Analog Output Option. This

option provides a filtered analog output that is representative of the displayed pressure

or temperature, and is provided via a BNC connector on the top of the unit. The source

parameter for the analog output is selectable in the Setup Menu between Pressure

(Pres) or Temperature (Temp). The output is scaled to match the 0 to FS range of the

selected source parameter over a variable internally generated reference voltage. This

reference voltage is selectable from 1.0 to 4.0 VDC in 0.1 V increments through the

Setup Menu. Filtering is dependent on the Digital Filter Setting (See System Setup

section for more information).

TEMPERATURE – The unit may be ordered with the Temperature Option. This option

allows the unit to read an external temperature sensor/transducer and display

temperatures between -20 to 100 °C (-4.0 to 212.0 °F). The temperature probe interface is

a standard ¼” Phone Jack.

 YSI 700 Temperature Input (Y7) – This option allows the unit to display

temperature measured by a YSI 700 series standard temperature probe.

 RTD Temperature Input (R1) – This option allows the unit to display

temperature measured by a standard 100 Ω RTD. This option supports

selectable temperature coefficients (alpha) to match that of the sensor or probe:

 0.00385 Ω/Ω/°C (most common)

 0.00392 Ω/Ω/°C
