Setting the Recorder
Precautions in Power Module Measurement
Input the voltage or current being measured at a level between 10% and 100% of the
measuring range. The instrument bases its calculations of all other parameters on the
frequency of V1. Extra care must therefore be taken when setting the input level of
V1. If the input level fails to fall within the given limits, there is no guarantee that the
measurement of any other parameters will be reliable.
Setting the Reference channel
Set the reference channel when “DELTA” or “RRJC” is set to “Mode.”
Setting the Unit
Set the Unit you want to use for calculation using maximum 6 alphanumericals or the
symbols :, #, %, &, ( ), *, +, -, ., and /.
When the setting parameters are loaded via communication from the connected recorder,
or imported from FD, Ω and
Ω
are replaced to “space,” and e to e.

Alarm type
Selecting the type of alarm
Select an alarm type for each alarm number from among the following:
• OFF (default set) : No alarm is set.
• H : Upper-limit alarm
• L : Lower-limit alarm
• RH : Rate-of-change upper-limit alarm
• RL : Rate-of-change lower-limit alarm
• dH : Difference upper-limit alarm
• dL : Difference lower-limit alarm
Note
• Alarms can’t be set if the input type is SKIP, or if the Math channel mode is OFF.
• If you make below changes, channel alarms will automatically be switched OFF:
• Input type.
• Measurement range.
• Reference channels of inter-channel computations.
• RRJC reference channels, reference channel inputs, or thermocouples.
• Setting Math channels ON, OFF, Math equations
Setting alarm values
Set one alarm value for each alarm number within the specified range, depending on the
type of input.
Setting Relays (Internal Switches)
Select the desired alarm output relay or internal switch (S01 to S60).
Note
As for the DA100 with the style number 8 or later, if you set an alarm relay as a relay to be
turned ON or OFF externally, you cannot select this relay for the alarm output.
