Option Description
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.
Server Port ModbusTCP server listen port (default = 502). Range:
0 to 65535, integer only.
Client Port Not available (disabled)
Gateway Router or access point to another network (default =
169.254.1.5)
Remote Server Not available (disabled)

Do an analog output test
For instruments with the analog output feature, do an analog output test.
1. Connect the analog outputs to the load resistors of the data
acquisition system.
Note: As an alternative, install a set of load resistors with 0.1% accuracy and
at least 0.25 W capability across the analog output. Load resistor values of
100, 250 or 500 ohms are typically used.
2. Let a tiny amount of particles flow through the instrument to get a
count in the test channel.
Note: One method to get counts is to use a zero count filter, and put a pin-hole
in the tubing that is between the filter and the instrument.
3. On the Basic Setup tab of the setup utility software, temporarily set:
• Count Cycles—1
• Sample Timing: Hold—10 seconds or more
4. Click Save Settings.
5. Select the Data Display tab, then click Monitor if shown so the data
shown can update continuously as each sample is taken.
6. Click Sample if shown to start sample collection.
7. When the Status value changes from "Count" to "Stop", measure the
voltage across the load resistors for each channel. Also note the
counts shown in the display for each channel.
8. Use the equation that follows to calculate the expected voltage from
the counts shown. Make sure that the measured and calculated
voltages agree.
Voltage = (((SC ÷ FC × 16) + 4) ÷ 1000) × RL
Where:
SC = sample count at the end of the sample period
FC = full-scale channel count. Refer to the analog settings in the
setup utility software.
