Operating sequence

Operating sequence

1.Turn Flow On in the setup menu of the QUESTemp°46.

2.Plug the Air Probe into the port labeled Flow on the side of the QUESTemp° 46.

3.Turn on the Air Probe ON and make sure the green lamp is lit.

• In the View or Run modes, airflow is displayed on the fifth screen.

Data Logging Airflow

To data log airflow in the QUESTemp° 46, the following two conditions must be met.

1.First, turn Flow On in the setup menu.

2.Second, make sure that a temperature sensor bar is connected to the Sensor 1 location (top) of the QUESTemp°46. Flow prints out with the Sensor 1 data therefore airflow data will only be reported if a sensor bar is plugged in. Airflow is recorded during the run mode at the interval the QUESTemp° 46 is setup for.

Batteries for Air Probe

The Air Probe uses a single NiMH Black&Decker VersaPak Gold battery. Typical operating time of the battery is between 6 and 8 hours.

To change the battery, push in and twist, counterclockwise, the cap on the bottom of the Air Probe. Pull out the battery. Insert a fully charged battery and replace the cap.

To recharge the batteries, set the battery into the VersaPack charger. The supplied charger accepts one or two batteries. A full charge takes 9 hours. An indicator light shows that the battery is properly charging and it will remain on as long as the battery is in the charger. Continuous charging is not a safety concern.

Operational Check

A verification module, 3M model 053-923, may be used to check the operation of the QUESTemp. Remove the top sensor bar and plug the verification module into the top of the unit. With the QUESTemp set to read in degrees Celsius, verify that the displayed readings match those printed on the module within +/-0.5°C.

If the readings are not within the +/-0.5°C tolerance, then have the unit serviced and calibrated.
