Start (Short press) Activates Run mode, initiates test with a sample greater than 0.5 g
Cal (Long press) Initiates weight or temperature Calibration (see Section 5, Maintenance)
Temperature / Time Edit Mode (Preparing a Test)
Temperature editing: (50
°
to 160°C in 5° steps
)
Temp (Short press) Enters Edit mode for the temperature setting, the value will blink.
Set

(Short or long press) Increases the value of the temperature setting.
Set

(Short or long press) Decreases the value of the temperature setting.
Tare (Short press) Accepts the blinking value and returns to Weigh mode.
Start (Short press) Exits Edit mode without saving changes.
Note: After 5 seconds of no activity the blinking setting is automatically saved and the mode returns to Weigh.
Time editing: (1 to 60 minutes in 30 second steps, 61 to 99 minutes in 1 minute steps)
The time parameter can be set to timed duration or AUTO (the test ends when the Analyzer detects the weight loss has
ended). Selecting AUTO or timed duration:
Time (Short press) Enters Edit mode for the time setting, the value will blink.
Time (Short press) While the time setting is blinking, toggles between AUTO and a time value.
Tare Accepts the blinking setting.
If AUTO is selected Weigh mode is entered.
If time duration is selected:
Set

(Short or long press) Increases the value of the time setting.
Set  (Short or long press) Decreases the value of the time setting.
Tare (Short press) Accepts the blinking value and returns to Weigh mode.
Start (Short press) Exits Edit mode without saving changes.
Note: After 5 seconds of no activity the blinking setting is automatically saved and the mode returns to Weigh.
Run Mode (Performing a Test)
A moisture determination test is initiated. The results in progress are displayed.
Start (Short press) Activates Run mode, initiates test with a sample greater than 0.5 g.
%g Changes the unit of the displayed result: weight (grams) > % Moisture > % Solids.
Stop (Short press) Manually stops the test in progress.
Print Sends the current displayed value to the RS232.
Result Mode
At the end of the test (Run Mode), the display blinks the test result.
%g Changes the unit of the displayed result: weight (grams) > % Moisture > % Solids.
Tare Exits to Weigh mode.
Print Sends the current displayed value to the RS232.
How to Prepare a Test
Moisture determinations can be made very simply. The three steps are:
(1) Setting the drying temperature (see Section 3).
(2) Setting the drying time, and (see Section 3).
(3) Preparing the sample to be tested:

Place the Pan Handler with empty test pan on the Pan Support (see Section 2).

Press Tare to zero out the pan weight.

Remove the test pan and place the test sample onto the test pan. The sample must be greater than 0.5g.

Spread the sample evenly across the test pan.

Place the test pan with the sample on the Pan Support. The weight value of the sample will be displayed.
Section 4. Test Optimization gives hints on determining optimal drying temperatures and times, sample
sizes, and proper preparation of samples.
How to Perform a Test
(1) Close the Heater Cover.
(2) Press
Start to begin the test (press Start again to stop the test in progress).
(3) When the test is over the display will blink showing the final result.
(4) To change the displayed units, press
%g .
(5) To print the current displayed value, press Print .
(6) Press Tare to exit to Weigh mode.
