Omega Engineering OS1592 manual Changing the Temperature from F to C or vice versa

OS1592 Infrared Fiber Optic Thermometer/Transmitter 3

NOTE:

The Emissivity setting as well as the temperature Engineering unit (°F or °C) are stored in the non-volatile memory. Removing the main power will not erase or change these settings.

3.1 - Changing the Temperature from °F to °C (or vice versa)

Press the	MODE		key to go to either the MAX , MIN, or DIF display mode.
Press the			key to change the temperature display from °F to °C or vice
		°F–°C

versa. The analog output 1 (1 mV/Deg) also follows the temperature display unit.

3.2 - Turning on the Display Backlight

Press the MODE key to go to either the MAX, MIN, or DIF display mode. Press the key to turn the display backlight ON or OFF.

3.3 - Using the Alarm Function

1. Press the MODE key to go to the HAL display mode.

2. Press either the or keys to set the high alarm value.

3. Press the SET key to enable the high alarm function. The	icon
appears on the display.

If the temperature exceeds the high alarm set point, the unit goes into an alarm condition. The icon on the display flashes, the alarm red LED turns on, and the internal relay energizes. The relay contacts are brought out to the terminal block J101 for ease of access.

4. To disable the high alarm function, press the SET key again, and the icon disappears.

NOTE:

1- The alarm temperature value as well as the alarm status are stored in the non- volatile memory. As a result, removing main power will not erase or change these

settings.

2- The alarm deadband is 10°C or 18°F.

3.4 - Analog Output vs. Temperature

The following equations relate the analog outputs of 4-20mA, 0/5VDC, 0/10VDC to measured temperature:

4-20mA:	Measured Temperature = [ (mA Output – 4) x (T2 - T1)] + T1
