Frequently Asked Questions (FAQs)

WEATHERPAK®    /     ZENO®    /     INTERCEPT™    /     WEATHERPAK® MTR

WEATHERPAK®

Q: Where is the serial number located on a WEATHERPAK®?
A: Units manufactured before June 2006 have the serial number on the top neck of the WEATHERPAK® under the radiation shields. Units manufactured from June 2006 and beyond have a label at the lower end of the canister.

Q: How do I orient my WEATHERPAK®?
A: Most WEATHERPAKS automatically align to True North. An internal electronic compass eliminates alignment errors. For those systems without an internal compass, there is a small notch on the side of the canister at the top. That notch should be oriented due south. Likewise, the RM Young wind monitor has a notch at its base. This notch should also be oriented due south.

Q: What If I want to orient my WEATHERPAK to True North instead of Magnetic North?
A: For WEATHERPAK®s with serial numbers 3004 and below click here for the procedure to set up your WEATHERPAK® compass with the magnetic declination for your area. For WEATHERPAK®s with serial numbers 3005 and above click here for the procedure to set up your WEATHERPAK® compass with the magnetic declination for your area.

Display/Receiver Box

Q: How long will the battery last without A/C power connected?
A: Two to three hours.

Q: How long will it take to give a dead battery a full charge?
A: 12 hours for a 90% charge, 24 hours for a 99% charge.

Q: Is there a schedule for recharging?
A: If the battery is being stored at or around 70° F, it should be charged every 12 months. At higher temperatures (up to 100° F) it should be charged every 6 months.

Q: Should the battery be fully discharged before recharging?
A: No. For lead-acid batteries, it is preferable to discharge as little as possible, and if discharged, to recharge as soon as possible. Typically, a battery discharged to 50% of its potential will last through 400 discharge-recharge cycles. However, a battery completely discharged will only last through 175 cycles.

Tower

Q: How long will my WEATHERPAK® run on the tower batteries alone?
A: Approximately 3 days. After three days, the WEATHERPAK® will still have power, but not enough for the radio to transmit.

Q: How many batteries are used in a HAZMAT tripod tower?
A: Nine D cell batteries.

Q: How do you load batteries in a HAZMAT Tower?
A: In the bottom of the tower top section, there is a silver plug with a slot in it. Using a large standard screwdriver, push down and turn the plug clockwise to release the bayonet mount. Remove the plug and the spring from inside the tower section. Nine D cell batteries are inserted with the Positive (+) end towards the junction box. Once all nine batteries are installed, place the spring in the tower section and then replace the plug, pushing it down and turning counter-clockwise until it locks into place.

WEATHERPAK® MTR

Q: How long will the MTR Display battery last without A/C power connected?
A: Two to three hours.

Q: How long will it take to give a dead battery a full charge?
A: 12 hours for a 90% charge, 24hrs to a 99% charge.

Q: Is there a schedule for recharging?
A: If the battery is being stored at or around 70° F, it should be charged every 12 months. At higher temperatures (up to 100° F) it should be charged every 6 months.

Q: Should the battery be fully discharged before recharging?
A: No. For lead-acid batteries, it is preferable to discharge as little as possible, and if discharged, to recharge as soon as possible. Typically, a battery discharged to 50% of its potential will last through 400 discharge-recharge cycles. However, a battery completely discharged will only last through 175 cycles.

Q: How long will the "D" cell batteries in the tower of my MTR WEATHERPAK® last?
A: Approximately 3 days.

Q: What are the accuracy/tolerance ratings of the various sensors?
A: See the Sensor Specification Sheets.

Q: Is the GPS antenna passive or active?
A: It is active.

ZENO®

Q: How do I reset the clock on my ZENO® 3200 or WEATHERPAK®?
A: To reset the clock in your ZENO® 3200 or WEATHERPAK® use the following procedure:

Connect a special com/test cable between the WEATHERPAK® (connects to bottom of cylinder) or the ZENO® 3200 (com3, db9 connector) and an available comport on your PC. Using HyperTerminal, open a window using the settings of 9600-baud rate, parity none, stop bits 1, and flow control to none (if 9600 does not give legible data, change baud rate to 1200). Plug in the power source to the ZENO® 3200/WEATHERPAK®. You should see a boot up message from the WEATHERPAK® within 10 seconds similar to that shown below.

INTERCEPT®

Q: What is the current version of Standard INTERCEPT® software?
A: V1.41.53.

Q: Does the current version of INTERCEPT® run on Windows® 7 and 8?
A: The current version of Standard INTERCEPT® will run on VISTA, Windows 2008 Server [versions SP2 or R2], Windows 7, Windows 8, Windows 2012 server, Mac OS X, or Linux. Testing on Windows 10 is currently in process.

Miscellaneous Communications Issues:

If you are communicating with a system using a laptop with no serial connector, and have a serial to USB adapter cable in order to connect, a driver will need to be downloaded for that adapter cable. Many of those cables have no such driver, and in the absence of said driver, the computer will not be able to create a COM port on which the system can communicate with the laptop. Locate the website for the manufacturer of the adaptor you are using and download the driver.  The driver should allow you to create a virtual serial port.  If you are unable to find the driver for your USB - Serial adaptor, you can try the following: Click here.

ALOHA® requires an available serial port to collect data from the Weather Station.

ALOHA® Q&A:
Q: What are the most current versions of ALOHA, Marplot, and CAMEOfm?
A: Since the software is updated as needed, it is recommended that you check the EPA  website (http://www2.epa.gov/cameo/download-cameo) regularly, for the most current versions.

Q: Can I run INTERCEPT® and ALOHA®/CAMEO® at the same time?
A: No. They usually use the same COM port, and Windows will not allow two or more applications on the same COM port.

Q: Can I use the Ethernet port on the MTR Receiver/Display to feed ALOHA®/CAMEO® software?
A: Yes. However, you will need to create a virtual serial port on your computer since ALOHA®/CAMEO® only recognizes COM ports for station input. If needed you can generate a virtual serial port for the IP connection using a driver from this link: http://www.hw-group.com/products/hw_vsp/index_en.html. MTR Receiver/Displays with firmware 3.10 and above can show the IP address of the Receiver through the touch-screen display. The port number used for the connection is 7734. If your MTR Receiver is older, please contact Coastal's Service Department for more information..
