KEY FUNCTIONS
! Read:
Press this key to read the %MC or relative moisture value of the material under test.
@ Check:
This key, when pressed with the Read key, checks the meter calibration. It also displays the number of readings in memory (up to 100), the average, and the highest stored reading. It also clears the memory.
# Set-Point:
This key programs the set-point value. A buzzer will alert you if the meter reads higher than the selected value. It also acts as a scroll key, depending on the function.
$ Scale:
This key sets the display scale to #1 (paper), #2 (refer­ence), #3 (baled scrap paper).It also acts as a scroll key, depending on the function.
CHECK CALIBRATION
Set the meter to Scale #1 (Paper). Press the calibration check key is in calibration if it displays 11.1% +/-0.2.
When checking calibration, there is no need to disconnect the external electrode, if attached.
If you check the calibration and the display does not read
11.1%, it is likely an indication of a low battery. If this occurs, change the battery immediately.
Continued use with a low battery may cause the meter to go out of calibration. If you have a fresh battery and the instru­ment still does not indicate an acceptable calibration, return it to DELMHORST for service. See Service for Your Meter section.

Note: When the battery is removed and then reconnected, the meter
displays its software version for one second and then turns itself off. After replacing the battery, you must reset the meter as described in Resetting the Meter section.
A hard Reset is required if, after changing the battery, the dis­play is frozen. This is sometimes caused by the interruption of contact between the battery and battery lead wire. Resolve this as follows:

Disconnect the battery. Press and hold the Read key for 15 sec­onds. Release the Read key. Press and hold the Check key for 15 seconds. Release the Check key. Connect a fresh battery to the lead wire in a single action, making sure to align the poles prop­erly and without interrupting contact. If the display remains frozen, repeat the procedure. If this procedure does not solve the problem, refer to the Service for Your Meter section.

INFORMATION ABOUT YOUR READINGS
Readings below the nominal range of each scale will be dis­played as a negative number. Readings above the nominal range will be displayed with a blinking number. All under­range and over-range readings should be disregarded. They are not added to the accumulated readings or used in calcu­lation of the average or highest reading.
The meter can accumulate up to 100 readings. After all 100 readings are stored, it will not add new readings until the memory has been cleared. It will also continue to display the average of all 100 readings as a reminder that the memory is full.
hTo add a reading to the sum of all the previously stored readings, release the read key
When taking and storing readings for a specific material, be sure to clear the meter before moving on to the next scale if you do not want to group all of the readings together.

and Corrugated Products
hSet the meter scale for #1 paper. Check that the contact
pins are firmly hand tightened.
hPush the contact pins into the paper product to their full
penetration if possible.
hPress the read key
two seconds.
Since the readings are the result of an “average” calibra­tion, if a high degree of accuracy is required, the meter should be checked on the specific material and corrections determined by the user.
Meter readings indicate moisture content at room tempera­ture of 70º F– 90ºF. Meter readings will be affected by lower or higher temperatures. Lower temperatures cause readings to be lower; higher temperatures cause readings to be higher than the actual MC.
The meter tends to read the highest moisture content that is in contact with both pins. If thick samples are not well equal­ized, it may be necessary to make tests at different depths to determine the degree of uniformity of moisture distribution in the sample.
If the meter is used on stock so thin that the full length of the pins is not entirely embedded in the thickness of the sample, the readings tend to indicate a lower than actual MC. This can be overcome by testing more than one sample in stacks.

Using the 0–100 Arbitrary Scale
This scale is used to test the moisture content of hygroscopic materials for which a calibration is not available. Depending on the material, a special application external electrode, instead of the integral contact pins may be required. Increasing readings on the 0-100 reference scale indicate higher levels of moisture content. These readings can be translated into percent moisture content once a calibration has been developed.

nal electrode to the meter.
hPush the contact pins into the material or apply the exter-
nal electrode.
hPress the read key
for two seconds.
The readings may also be used for comparative tests, after meter readings have been related to given conditions for the materials involved. When the meter is used as a gauge for comparative tests, readings should be taken on samples con­sidered to be at “safe” levels or in satisfactory condition. These readings are then used as the “standard” against which subsequent readings on the same material are evaluated.
The “standard” for any given material is related to safe stor­ability or any other property which is important for further production processing.

Testing Baled Scrap Paper
hSet the meter scale for #3 baled scrap paper. Attach an
external electrode to the meter.
hPush the external electrode into the material being tested. hPress the read key
two seconds.
The level of accuracy of meter readings depends on a number of factors: similarity between the material tested and sam­ples on which the calibration was made; moisture distribu­tion; and chemical application or processing which may affect the electrical properties of the paper product
The required electrode is the H-4 with a (10”or 18”). A sharp, steel rod to open the hole for the prod may be helpful if the bale is very dense.

A few meter readings in a limited number of specific areas of a large mass can not be projected to indicate an average moisture content of an entire bale.The readings can be very helpful in providing an indication of the overall moisture con­dition inside the bale and to detect areas of excessive mois­ture.
Meter readings may be used as an arbitrary guideline in determining whether or not to accept or reject the material. Since checking the moisture condition of bales is performed when buying and selling, the specific value of the meter read­ings remains an element to be agreed upon between buyer and seller. Such an agreement should consider not only a spe­cific “range” of readings, but the number and location of where they are taken.
The following ranges can be used as a guideline and may help to interpret the readings:
hReadings of 5%–10%, with EMC to 60% RH are usually
considered “dry”.
hReadings from 11%–20% with EMC to 95% are usually
considered “acceptable” but should be taken with some reservation.
hReadings of 20%-40% are considered “wet” and unac-
ceptable.
CARE OF YOUR METER
To keep your meter in good working order: hStore your meter in a clean, dry place. The protective
carrying case provided is an ideal storage place when the meter is not in use.
hChange the 9-Volt battery as needed. Continued use with a
low battery may cause the meter to go out of calibration.
hChange contact pins as needed. Keep pin retainers hand
tightened.
hClean the meter, contact pins, and probes with any
biodegradable cleaner. Use the cleaner sparingly and on external parts only. Keep the cleaner out of the external con­nector. DO NOT IMMERSE THE METER OR ANY ELEC-
TRODE IN WATER.
hRemove the battery if the meter will not be used for one
month or longer.
