4.3
Parameter Types and Protect Levels
The parameters are classified into the following groups depending on
the main objective. Use of the protect setting in the condition data
allows a limitation to be imposed on the settable parameters.
Condition data:
A group of parameters that set up basic actions
such as the sampling rate and operation type for
each control.
Scaling data:
A group of parameters relating to measurements
such as scaling.
Linearize data:
A group of parameters relating to the function of
correcting the linearity of an input value and
display value.

4.5 Protect Levels
Protect level 0 (PL0): Allows all parameters to be displayed and
set.
Protect level 1 (PL1): Allows condition data
*1
and scaling data to
be displayed and set.
(*1) Protect level, range, averaging times
(setting sampling) and BCD output type only.
Protect level 2 or 3
(PL2, 3):
Allows only protect level in condition data to
be displayed and set.
4.6
Setting Condition Data
Condition data is a group of parameters for setting up basic actions such
as a protect level, measurement range, and each con
trol’s operation
type.
(1) Press the Enter key and the Mode key during measurement
operation to enter the condition data setting mode.
(2)
Press the Mode key to move to protect level setting.
(3) Press the Mode key to display the current protect level.
(4) Set up the desired protect level using the Increment key.
(This setting example sets the protect level to PL1.)
PL0: Displays all the parameters.
PL1: Displays only the condition and scaling data.
PL2/3: Displays only the protect level.
* Press the Mode key to skip the setting of this item.
(5) Press the Mode key to move to peak-hold-type setting.
(6) Set up the peak hold type using the Increment key.
(This setting example sets peak hold type to PH.)
PH:
Holds the maximum display value.
PV:
Holds the minimum display value.
PVH:
Displays (holds) the difference between the
maximum
and minimum values.
* Press the Mode key to skip the setting of this item.
(7) Press the Mode key to move to range setting.
(8) Set the range using the Increment key.
(This setting example sets input range to 14)

(9) Press the Mode key to move to averaging count setting.
(10) Set the number of averaging times using the Increment key.
1: Single (No averaging) (approx. 25 times/sec)
2: Twice averaging (approx. 12.5 times/sec)
4: Four-time averaging (approx. 6.25 times/sec)
8: Eight-time averaging (approx. 3.125 times/sec)
10: Ten-time averaging (approx. 2.5 times/sec)
20: Twenty-time averaging (approx. 1.25 times/sec)
40: Forty-time averaging (approx. 0.625 time/sec)
80: Eighty-time averaging (approx. 0.31 time/sec)
100: Hundred-time averaging (approx. 0.25 time/sec)
200: Two hundred-time averaging (approx. 0.13 time/sec)
* Press the Mode key to skip the setting of this item.
(11) Press the Mode key to move to moving averaging count
setting.
(12) Set the number of moving averaging times using the
Increment
key.
OFF: No moving averaging 8: 8 times
2: Twice 16: 16 times
4: 4 times 32: 32 times
* Press the Mode key to skip the setting of this item.
(13) Press the Mode key to move to step-wide setting.
(14) Set up step-wide using the Increment key.
1: Normal display
2: Only even numbers in the least significant digit
5: Only "0" or "5" in the least significant digit
0: Only "0" in the least significant digit
* Press the Mode key to skip the setting of this item.
(15) Press the Mode key to move to display blank setting.
(16) Set up display blank using the Increment key.
OFF: Normal brightness condition (brightest)
b-3: Bright
b-2: Slightly dim
b-1: Dim
ON: display lights off
* Press the Mode key to skip the setting of this item.
(17) Press the Mode key to move to digital limiter type setting.
