Measurement Expansion module:
H0000: CH1 ~ CH8 are all used
internal cold junction compensation.
(fact
ory default)
H0009: CH1 ~ CH8 are all compensated by the
external cold junction
temperature transmitted from the DTM host.
H0001: CH1 is the external cold junction temperature, and the remaining
channels are all used the temperature value of CH1 as the
external cold
junction compensation.
H0002: CH2 is the external cold junction temperature, and the remaining
channels are all used the temperature value of CH2 as the external cold
junction compensation.
H0003: CH3 is the external cold junction temperature
, and the remaining
channels are all used the value of CH3 as the external cold junction
compensation.
H0004: CH4 is the external cold junction temperature, and the remaining
channels are all used the temperature value of CH4 as the external cold
junction
compensation.
H0005: CH5 is the external cold junction temperature, and the remaining
channels are all used the temperature of CH5 as the external cold
junction compensation.
H0006: CH6 is the external cold junction temperature, and the remaining
channels
are all used the temperature value of CH6 as the external cold
junction compensation.
H0007: CH7 is the external cold junction temperature, and the remaining
channels are all used compensated by using the temperature value of
CH7 as the external cold junct
ion.
H0008: CH8 is the external cold junction temperature, and the remaining
channels are all used the temperature value of CH8 as the external cold
junction compensation.
 Note:
1) Write content H00yz according to DTM-DOx, DTM-CTx series accessory station number (y: 1 ~ F) and channel
(z: 0 ~ 7), and so on. Example: If you want to assign " output 2 of input CH1" of the measurement expansion
module with internal station number address 2 to the "CH1 terminal" of DTM-DOx series accessories of internal
station number address 4, write the content "H0040" into address H2198
2) When using CT1, first CT1 corresponds to output 1, and output 1 must be assigned to use [expansion cassette],
and output 1 corresponds to the same host or measurement expansion module, and the corresponding DTM-
CT030 station number can choose 1 ~ F
。
3) When using CT2, first CT2 corresponds to output 2. Output 2 can be designated to use [Expansion Cassette] or
[I / O Expansion Module]. When [Expansion Cassette] is specified for output 2, output 2 must correspond to the
same host or measurement expansion module, and the corresponding DTM-CT030 station number can be
selected from 1 ~ F, or the same DTM-CT030 as CT1. ; When [IO Expansion Module] is specified for output 2,
output 2 must correspond to the same IO expansion module, and the corresponding DTM-CT030 station number
can only select 9 ~ F, and cannot be the same DTM-CT030 as CT1. Only a second DTM-CT030 can be installed,
and the corresponding IO expansion module must be the same as the second DTM-CT030 station number
。
4) Example: to use the CH1 temperature value of host as the external cold junction compensation of other channels,
write the content [H0001] into the address [H0260]. The selection of CH1’s input can be PT100 or thermocouple
type. x indicates the internal station number of the host or measurement expansion module.
