    b. 100°C [212°F]
    c. Ambient temperature
    d. Expected cargo temperature
2. 8.34 A thermowell used to measure temperature must be filled with a suitable heat-transfer liquid.
    a. True
    b. False
    c.
    d.
3. 8.42 In motion is defined as continuously raising and lowering the probe above and below the desired temperature measurement depth, by approximately how much?
    a. 15cm [6 inches]
    b. 1metre [40 inches]
    c. 30cm [12 inches]
    d. 50cm [20 inches]
4. 8.40 When first received from the manufacturer or equipment supplier, what should happen to a new liquid-in-glass tank thermometer?
    a. It can be used immediately because the manufacturer calibrates the thermometer before it is shipped
    b. It must be checked to see that the liquid column is intact, then it may be used since the manufacturer will have calibrated the thermometer.
    c. It must be checked to see that the glass stem is not cracked or broken, then it may be used since the manufacturer will have calibrated the thermometer
    d. It must be compared against a thermometer certified by a National Standard body or an equivalent thermometer of traceable accuracy.
5. 8.02 Does API MPMS Chapter 7/ISO 4268 make any references to the construction of portable electronic thermometers?
    a. Yes
    b. No
    c.
    d.
6. 8.25 According to API MPMS Chapter 7 the minimum amount of time that an in motion probe should stay in a product with an API gravity less than 20 is?
    a. 80 minutes
    b. 30 minutes
    c. 75 seconds
    d. 10 seconds
7. 8.49 What temperature is to be used during an ROB survey if there is only 5 cm [2 inches] of liquid in the bottom of the tank?
    a. The measured temperature at the middle of the liquid
    b. Standard Temperature
    c. The average temperature of the product in the tank before it was discharged
    d. The temperature stated by the vessel s representative
8. 8.06 On a portable electronic thermometer, what should be checked at least once per month?
    a. The junction between the cable and the probe for mechanical damage
    b. The cable insulation for cuts, breaks, or abrasion.
    c. Two or more temperatures near the ends of the range of the probe
    d. Answers a., b. and c. are all correct
9. 8.17 If a tank has more than 4.5 m [15 feet] of liquid, what is the minimum number of temperature readings that must be taken?
    a. 3
    b. 5
    c. 1
    d. one every 1 m [3 feet]
10. 8.22 According to common industry practice how should the working spot check (field check) of a portable electronic thermometer be performed?
    a. Daily comparison to another portable electronic thermometer
    b. By comparing it to a liquid-in-glass thermometer, before each use or once per day
    c. By checking the unit weekly, for accuracy
    d. Calibrate against a thermometer (traceable to national standards) at prescribed intervals
