Power On/Off
Turn the ON/OFF switch (located on unit’s upper left side) to its ON position. To turn off, switch it to the OFF position.
Self-Diagnostics
Each time the unit is turned on it will perform a self-diagnostic of the unit. This will activate all the LCD display segments (Fig. 2). After five seconds, the display will indicate
“OUT WBGT” in °C. If the LCD display remains blank (or fades), any segment fails to activate, an “E #” code appears (even momentarily), or if the “LO BAT” indicator
appears anytime during operation do not use the instrument until the reason for the message or condition has been determined and corrected.
WARNING
Each time the unit is turned on, it performs a self-test. If the self-test fails, or an error code is displayed, do not use. Doing so may adversely affect product performance
and result in sickness or death.
Monitor Mode
Press SELECT to toggle between temperature scales (°C/°F).
Press VIEW to scroll through the individual sensor readings (WB, DB, GT) and WBGT readings. Press the VIEW button until the desired reading is displayed.
Analog/Recorder Output (monitor mode only)
An analog signal proportional to the display value [0 mV at 0. °C (32.0 °F) to 1000 mV at 100.0 °C (212.0 °F)] is provided via a mini phone jack located on the monitor’s
lower left side. This can be connected to a compatible strip chart recorder. The recording device must have a minimum input impedance of 1000 ohms. Error is less than
0.1 °C relative to the display value.
DATA LOGGING (Optional)
The Data Logger/RS232C serial data output port accessory is an option providing nonvolatile digital data storage and communications capabilities (Fig. 3). Up to 511 data
sets (record #, time, date and the five monitor functions) may be logged and downloaded to a computer. Logged data will not be lost if the unit is turned off, the sensors are
removed, a battery failure occurs, or the memory becomes full.
WARNING
The RSS-214DL RS 232 serial data output port must be used in a non-hazardous area only. Using the data output port is not an intrinsically safe operation. Failure to
do so may result in sickness or death.
