Description

Press the [DISP] key for three seconds to enter the SET mode.

Select the [ ] display by using the [ ] key. Then press the [ENT] key.

Use the [ ] key to select the desired channel.

Note that channel No.1 cannot be of the ‘DELT’ type. Press the [ENT] key.

Use the [ ] key to select [

].

Press the [ENT] key.

 

The display which appears will allow you to enter a reference channel number. Note that the reference channel number must be lower than that of the channel being set. Therefore channel

In case of VOLT the display which appears will show the same minimum value of the recording span as of the reference channel.

Use the [ ] and [ ] keys to select the minimum value (SPAN L).

Press the [ENT] key.

Note that in case of VOLT, the input range of the DELT-channel must be within the range of the reference channel. In case of TC, RTD, the minimum/maximum span values can be found by taking the ±value of the input range width. E.g. input range of TC type L = –200 to 900°C: minimum/maximum span values will be at ±1100 °C. The difference in measured value from the reference channel will be recorded on the DELT-channel.

The display which appears will show the same maximum value of the recording span as of the reference channel.

Use the [ ] and [ ] keys to select the maximum value (SPAN R) in the same way as described under ‘SPAN L setting’. Note that SPAN L cannot be equal to SPAN R. Press the [ENT] key.

[ ] is displayed and the setting is completed. Press the [ENT] key to set another channel; or press the [DISP] key for three seconds to return to the OPERATION mode.

6. SET MODE

NOTE If you press the [ESC] key in the middle of setting, the indication returns to the

[ ] and already set data will be aborted.
