Section IV – Operating Instructions
432 Bias Comp – This mode assumes that a temperature-compensated mount is
attached. The Bias Comp mode balances both channels just like the 432 Compatible
mode, the difference is the voltmeter readings from only Channel 1 are used in the simple
power equation of
P=(V[OFF] 2 - V[ON] 2 )/R . This method is recommended for
standards lab use with 478, 486, 8478 series thermistor mounts, because the errors from
only one channel are transferred, while in a lab the mount environment can be stabilized
using insulation.
ReZero Unit (Write Only)
Located SETUP — Instrument menu and on the main display window. During rezero the
system changes the DAC value to equal the reference resistor value. Since the primary
reading is DAC
– RV, this creates a zero voltage difference after a re-zero.
Network Options
Located SETUP — Instrument menu. Configure the 1830A remote communication via
TCP/IP. The 1830A is controlled via TCP/IP through an Ethernet cable connection.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the most popular network
protocol and the basis for the Internet. Its routing capabilities provide maximum flexibility
in an enterprise-wide network. In Windows XP TCP/IP is automatically installed.
On a TCP/IP network, you must provide IP addresses to clients. Clients may also require a
naming service or a method for name resolution. This section explains IP addressing and
name resolution for Network Connections on TCP/IP networks. It also describes the FTP
and Telnet tools that are provided by TCP/IP.
Network Options menu contains 12 selections.
1. IP Address
2. Subnet Mask
3. Gateway
4. Host Name
5. Domain Name
6. DNS Server 1
7. DNS Server 2
8. MAC Address
9. Network Link Activity
10.LAN Configuration
11.Reset LAN Configuration
12.Network Enable
IP Address (Read/Write):
Located SETUP — Instrument — Network Options menu. Internet Protocol (IP) address is a
numerical label that is assigned to devices participating in a computer network, that uses
the Internet Protocol for communication between its nodes. An IP address serves two
principal functions: host or network interface identification and location addressing.
