Hach MET ONE 6000 Manuel D'utilisation De Base page 18

Option Description
Sample Mode Sets the sample mode.
Auto—Sample data collection starts automatically
when power is applied to the instrument.
Manual—Sample data collection does not start
automatically when power is applied to the
instrument. Sample data collection must be started
manually. Refer to
Note: Ethernet units with analog output cannot be
set to Manual because there is no bi-directional
communication with the central monitoring
software. These units always start in Auto mode.
Flow Units Sets the air flow units. Options: CFM (cubic feet per
minute) or LPM (liters per minute).
7. If an optional external light stack is connected to the instrument, use
the Diagnostics section to set the status indicator light to flash or not
flash for one of the colors to identify that the wiring is correct.
Note: It is not possible to save the diagnostic settings and they have no effect
on the instrument operation.
8. For units with analog output, change the settings for the 4–20 mA
analog output in the Analog section.
Option Description
Full Scale Sets the particle count for each channel that corresponds to a
20 mA output signal (default = 1000). A zero particle count
corresponds to a 4 mA output signal.
Note: Count alarms are not reported to the central monitoring
software. Configure the central monitoring software to trigger
count alarms as necessary.
Output Sets the output state. Set to Normal for normal operation.
State Zero—Holds the output at 4 mA.
Span—Holds the output at 20 mA.
9. For serial communication (RS485 units only), change the
communication setting in the Serial section. Options: FXB, Modbus,
R48XX Compatibility, FXB1. If Modbus is selected, enter the slave
address. When the address is 31 or less, use the dip switches on the
18 English
Manual operation on page 22.
bottom of the instrument to set the address. Refer to
output with Modbus RTU protocol
Note: If an address of 32 or higher is entered, the dip switch setting are
ignored and the entered value is used.
10. For pulse communication (RS485 units only), select the channel size
for the Channel 2 pulse output in the Pulse section (default = Count
Channel 2). The Channel 1 pulse output always corresponds to the
Channel 1 particle size.
11. For Ethernet communication (Ethernet units only), refer to
the Ethernet settings on page 18.
12. Click Save Settings to save the changes.
Configure the Ethernet settings
1. For Ethernet units without the analog output feature, change the
Ethernet settings in the Ethernet section. The Ethernet settings
should only be changed by a network professional.
Option Description
MAC Media access control—Shows the unique permanent
hardware address (read-only)
DHCP/APIPA Enables or disables static or dynamic IP addressing by
connection to a DHCP server (default = disabled). When
enabled, the instrument gets an IP address and subnet
mask automatically when power is applied.
If a DHCP server is not available, the instrument uses
APIPA for an IP address and subnet mask.
• APIPA IP address range: 169.254.0.0 to
169.254.255.255
• Subnet mask: 255.255.0.0 (Class B network)
IP Address For static IP addresses, each LAN-based instrument
must have a unique IP address. Range: 169.254.0.0 to
169.254.255.255 (default = 169.254.1.2).
Subnet Mask Instruments of the same type that communicate with a
single software package (i.e., FMS) use the same
subnet mask (default = 255.255.0.0). Range: 0 to 255,
integer only.
