UP AND RUNNING ...............................
1. UP AND RUNNING 3. MEASUREMENTS 1. Make sure the wet bulb’s wick is clean. Fill the reservoir with distilled water. 2. Place the QUESTemp in the work area in a safe location approximately 3.5 feet off the ground. 3. Turn the unit ON. If the battery voltage displayed during the power-on sequence is less than or equal to 6.4 volts, replace or recharge the batteries. 4. Be aware that the sensors require 10 minutes to stabilize to a new environment. 5. Press the RUN STOP key to begin datalogging.
. OPERATIONAL MODES The Heat Index is defined over a temperature range of 70°F - 120°F (21°C 49°C) and a relative humidity range of 30% - 99%. Outside of this range, the instrument will show dashes in the display for the Heat Index. ►VIEW SETUP The Humidex, used primarily in Canada, works on the same concept as the Heat Index. The values are slightly different. The Humidex is defined over a temperature range of 70°F - 109°F (21°C - 43°C) and a relative humidity range of 20% - 99%.
PRINT Allows printing to a parallel or serial printer or to a computer. The unit will recognize the cable plugged in and configure itself for serial or parallel. If no cable is plugged in it will default to serial. Press I/O ENTER to begin printing. Press RUN STOP to return to the menu. DOWN ARROW Changes items appearing in the display. Scrolls down. RUN STOP From the menu or view modes, pressing this key starts or stops the run mode. Pressing this key will exit the setup, print or reset modes.
7. DATA LOGGING A series of dashes appear in the display if one of the following occur: • the Heat Index or Humidex is outside of its allowable range • the temperature is outside of its allowable range • a temperature sensor has failed • stay times temperatures are outside of the their defined range Data from each sensor is recorded at the interval set by the logging rate. Every time RUN STOP is pressed, a session is either started or ended in memory.

RELATIVE HUMIDITY SENSOR 9. PC COMMUNICATIONS The QUESTemp°36 has the flexibility to be set up and controlled through computer software. The programmable start and stop time feature is only accessible through the computer. The instrument also has the capability of sending live data while measuring. These features are best utilized using QuestSuiteTM software. To write custom software for working with the QUESTemp°36, call Quest Technologies for the programming commands. 10.
Cable lengths of up to two hundred feet (61 meters) may be used without a decrease in accuracy provided the environment does not contain strong electromagnetic fields. OPERATING SEQUENCE 1. 2. 3. Turn FLOW ON in the setup menu of the Questemp°36. Plug the Air Probe into the port labeled FLOW on the side of the Questemp°36 . Turn on the Air Probe ON and make sure the green lamp is lit. In the VIEW or RUN modes airflow is the fifth screen displayed.
battery. If the rechargeable battery pack ever needs to be replaced, it can be accessed by removing the screws from the bottom panel of the unit. 15. SPECIFICATIONS The 2-position switch located in the battery compartment must be set by the user if the power supply method is changed. The up position is for the 9 volt battery. The down position allows for either the AC adapter or the rechargeable batteries.
Remote Sensor Bars: 2 x 15pin D-sub jacks are located on the side of the unit for plugging in 1 or 2 additional sensor bars by using remote cables up to 200 feet (61m). The top sensor bar can also be remote with a cable. 16. APPENDIX A : HEAT EXPOSURE TABLES ACGIH Power Options: 9V alkaline, 7.2V NiMH rechargeable pack (charged in the unit), or AC adapter wall power cube (AC adaptor will operate the unit or recharge the NiMH battery pack) Screening Criteria for Heat Stress Exposure.
ACGIH CLOTHING CORRECTIONS PHEL Curves (Continued) The following clothing corrections are in degrees Celsius. When a clothing correction is entered into the setup portion of the Questemp°36, the value is added to the WBGT only for looking up the stay times. The WBGT value displayed by the unit does not reflect corrections. WBGT(F) I 98.0 2:55 99.0 2:40 100.0 2:30 101.0 2:20 102.0 2:10 103.0 2:00 104.0 1:50 105.0 1:40 106.0 1:35 107.0 1:30 108.0 1:20 109.0 1:15 110.0 1:10 111.0 1:05 112.0 1:00 113.
