1.  The GAC 2100 warm-up period after being turned is:

```{=html}
<!-- -->
```
a.  2 hours

b.  15 minutes

c.  30 minutes

d.  There is no warm-up period.

2.  The standard weight of grain required to accurately measure moisture
    is:

```{=html}
<!-- -->
```
a.  Approximately 250 grams

b.  350 grams

c.  Exactly 375 grams

d.  There is no standard weight, the sample hopper must be filled with
    enough grain to fill the measuring cell inside the
    instrument[.]{.underline}

3.  The GAC 2100 gives an error indication instead of a moisture reading
    when:

```{=html}
<!-- -->
```
a.  There is a greater than 36 F temperature difference between the
    instrument and the grain sample.

b.  The instrument temperature is outside the 50-104 F range limit.

c.  The temperature of the grain is outside the 32-104 F range limit.

d.  Any of the above, singly or in combination.

4.  When the GAC 2100 gives an error indication and a moisture:

```{=html}
<!-- -->
```
a.  Record the moisture on the pan ticket and note the error number.

b.  Ignore the error indication and record the moisture on the pan
    ticket.

c.  Check the error number in the GAC 2100 operator's manual and take
    appropriate action.

d.  Cycle the dump cell and try again.

<!-- -->
```
a.  Nearest hundredth percent.

b.  Nearest tenth percent.

c.  Nearest whole percent.

d.  Nearest half percent.

6.  Routine maintenance of the GAC 2100 instrument involves cleaning the
    test cell:

```{=html}
<!-- -->
```
a.  At least one time per week.

b.  On a daily basis.

c.  When the instrument is tested.

d.  At least one time per hour.

```{=html}

7.  When the grain sample temperature exceeds either the upper or lower
    temperature limits of the GAC 2100:

```{=html}
<!-- -->
```
a.  Wait for the sample to reach room temperature.

b.  Follow the temperature equalization process in the moisture
    handbook[.]{.underline}

c.  Run the sample through the GAC 2100 until it reaches a temperature
    within the established ranges.

d.  Any of the above

```{=html}
<!-- -->
```
8.  When the moisture reading exceeds the approved calibration range:

```{=html}
<!-- -->
```
a.  Another determination shall be made from the work sample or the file
    sample.

b.  Only one moisture determination is made and a qualifying statement
    is recorded on the certificate.

c.  Take the instrument out of service.

d.  Move the instrument to another location.

9.  When the power is turned on, the GAC 2100 automatically begins a
    self-check to determine the status of:

```{=html}
<!-- -->
```
a.  Load/strike off mechanism

b.  Unload function

c.  Empty test cell weight

d.  Conductance/capacitance measurement circuitry

e.  All of the above

```{=html}
<!-- -->
```
10. When grain is dumped into the test cell, the unit calculates
    moisture by measuring the following variables:

```{=html}
<!-- -->
```
a.  Weight

b.  Temperature

c.  Conductance

d.  Capacitance

e.  All of the above

```{=html}

11. The sealed membrane keyboard contains 20 pressure sensitive touch
    switches requiring light finger pressure to actuate each key.
    Identify the keyboard function that is incorrect:

```{=html}
<!-- -->
```
a.  Valid key closures are denoted by short bursts and invalid
    keystrokes have longer tone bursts.

b.  Backspace key allows re-test without dumping grain from scale.

c.  Keys with small arrows navigate through display screens.

d.  Load key begins the test cycle (upper right hand corner).
