• One button operation
• Rugged case
• SD card for logs
• Runs on 6X AA Batteries
• Optional 12v DC power supply

Component Descriptions

Button Functions

Button Bump: Bump test
Button Cal: Calibration

Led indication

Error Codes
The dock will give an error code by blinking the Bump or Calibration LED red and sounder will beep.
Count beep/blinks to refer the right error code see chapter trouble shooting

Operating the PDM Mono Dock

Powering the PDM Mono Dock

The PDM Mono Dock can be powered by 6X 1.5V AA alkaline batteries or by applying a 12V dc external power supply

Tuning on the PDM Mono Dock

Turn on the PDM Mono Dock by pressing either the Calibration or Bump button. The PDM Mono Dock will automatically wake up out of sleep mode which gets activated when not used. Through the use of this sleep mode up to 1600 tests can be performed on 6X AA batteries.

Calibration Gas

Use the PDM Mono Dock with certified valid calibration gas. Use a demand flow regulator connect the regulator with the gas sampling hose to the gas inlet right side of the case.

By default the PDM Mono Dock is programmed to use default gas concentration, as span gas for your detector. If you have a bottle with a different concentration please change this setting to the right values. Chapter Load PDM Mono Dock Configuration

Default value span gas:

O2: 18%
CO: 50ppm
H2S: 10ppm
SO2: 10ppm
NH3: 50ppm

Preform Bump/Calibration

Bump test
Place an turned on warmed up detector into the detector bay.
Ensure that Gas concentration in gas bottle matches with the gas bottle setting in the config.ini
Press the Bump button.
Now the LED around the button will glow blue, when finished the LED will glow green.
If an error occurs the LED will blink the error code in RED. (see Error Codes for explanation)
If error stays existing after a retry try to determinate your error with chapter troubleshooting.

Calibration
Place an turned on warmed up detector into the detector bay.
Ensure that Gas concentration in gas bottle matches with the gas bottle setting in the config.ini
Press the Cal button.
Now the LED around the button will glow blue, when finished the LED will glow green.
If an error occurs the LED will blink the error code in RED. (see Error Codes for explanation)
If error stays existing after a retry try to determinate your error with chapter troubleshooting.

SD Log
After testing an detector successful or fail, the PDM Mono Dock writes the data onto the SD card. Bump, Calibration and event log of the tested instrument will be saved.

Load PDM Mono Dock configuration

Configure internal Clock

To configure the internal clock use the WatchGas PDM IR Link software in combination with the IR Link.

1. Connect the IR Link and open the software
2. Press “cal button” and keep pressed until the LED turns yellow
3. Select correct COM port and select “open”
4. The MonoDock led will go Green and the time is set corresponding to the PC time.

Setting up the configuration File

In the Configuration File saved on the SD card serval information is stored.

1. Location: fill the Location of the bump station which will be logged into the datalog
2. Bump time: Time of gas exposure during bump test
3. Cal time : Time of gas exposure during calibration
4. Gasbottle: types of supported gas including the expected concentration in the bottle
5. Expiry: date of Gas bottle expiry
6. Lot: Lot number of used gas bottle
7. For each gas type the option to fill the Low/High and cal/bump due.

Configuration of the gas is automatically changed in the detector corresponding the config file. If you don’t want the dock to change the alarm settings you should uncommit the lines with “; “.

A config example is include on the last page of the manual.

SD Logs

Every test is saved onto the SD Card, PDM Mono Dock log files are saved in a Comma Separated CSV file witch can be parsed by a spreadsheet program.

Get csv from SD

Place the SD card with data into your computer and select the file you want to have
