Connect the pressure to the Labquest and turn the lab quest on or select "New if it's 12 3. Attach the syringe directly to the nozzle on the pressure sensor. Twist gently and ensure 4 The Labquest should display the pressure in the syringe, typically 92-97 kPa if everyth Begin by adjusting the volume of the syringe so that the tip of the black part of the plunger is lined up exactly on 10.0 mL. Failing to do this first step can damage the sensor, so please remember to do this every time you connect the syringe. 1. already on. Choose "Discard' if prompted that there is a snug seal.Question

On 12 and 13 I got a negative scientific on one and a positive on the other. Did I make a mistake typing it into my calculator?
