Omega Engineering OS1592

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 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

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

display unit.

3.2 - Turning on the Display Backlight

Press the 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 key to go to the HAL display mode.

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

3. Press the 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 key again, and the

icon disappears.

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 = [(mAOutput – 4) x (T2 - T1)]+ T1
