Setting the Recorder

• AC Power monitor

• Setting the Wiring Method for the power monitor

Select from the following methods:

Single-phase two-wire (1Ph2W)

Single-phase three-wire (1Ph3W; 3-wire input modules only)

Three-phase three-wire 2 Voltage 2 Current (3Ph3W-2I; 3-wire input modules only).

Three-phase three-wire 3 Voltage 3 Current (3Ph3W-3I; 3-wire input module only).

Three-phase four-wire (3Ph4W; 3-wire input modules only).

• Setting the Input Range

Select from the following ranges: 250V-0.5A/250V-5A/25V-0.5A/25V-5A.

This setting is common to all channels. Any change to this setting also changes

the settings of the rest of the channels. Impose a voltage or current signal to the

input module within the limits you set here.

Note

If the connection method or input range is changed, alarm setting is turned off.

• Strain

The measurement mode should be 2 k, 20 k, or 200 k. The measuring ranges are as

shown below depending on the measurement modes and gauge methods.

Gauge method

2 k

20 k

200 k

1-gauge method

-2000 to 2000 µε

-20000 to 20000 µε

-200000 to 200000 µε

2-gauge method

-1000 to 1000 µε

-10000 to 10000 µε

-100000 to 100000 µε

4-gauge method

-500 to 500 µε

-5000 to 5000 µε

-50000 to 50000 µε

Note

If you have connected any new strain gauge or changed the measuring range initial balancing

is necessary (Initialization of settings or reconfiguration of the system also changes the

measuring range back to its default). See section 7.17.

• PULSE (not possible for DR130/231/241)

Select the RATE or Gate range.

• DELTA (difference between channels)

Computation can be done only in the same unit. Destination channels should lie
within the first channel No. to the last channel No. range. The number of the reference
channel (REF) should be lower than the number of the destination channels. The

default setting for the reference channel is 01.

The type of input and the measuring range in the destination channel are the same

as for the reference channel. After setting the DELTA (difference between channels),

if you attempted to change the type of input and the measuring range, setting the

difference between channels is released, thereby the type of input and the measuring

range in the destination channel are returned to their original settings, and the span is

returned to its initial value.

• RRJC (Remote RJC, available for instruments with the optional MATH function, only)

Reference channel (RJC): Within the setting range of reference channel No.

TC (thermocouple) must be selected as the type of input to the reference channel.

If the channel No. or type of input for the reference channel, or the type of

thermocouple is changed, the alarm function will be turned OFF.

If the type of input for the reference channel or the type of thermocouple is changed,

the RRJC settings will be cleared and the type of input and measuring range for the

reference channel will be set to the one which was in effect before the change was

made. The span will be set to the initial value of the measuring range.
