Troubleshooting of Compensation
5
Changing the unit:
a / f / p / n / µ / m /None/ k / M / G
5
Set each compensation coefficient with the
numeric keypad, and press [SET] .
Settable range A: -999.999 to 999.999
B: -9.99999 G to 9.99999 G
To return to the previous screen without changing the setting
value, press [SET] when the screen is blank (the state after
[C] is pressed).
[-] Inputs the unit with a minus (-) sign.
[×10 3 ] Increases the prefix of the unit.
[/10 3 ] Decreases the prefix of the unit.
[C] Repeats the input.
[CANCEL] Cancels the setting.
6
Press [EXIT] to close the setting screen.
[RESET]
Will be set to the default value.
(A: 1, B: 0)
• If the same parameter is selected multiple times and a different compensation coefficient is set
for each of them, the compensation coefficient of the parameter with the smallest number is
used to perform scaling for the parameters of all the parameter numbers. (The compensation
coefficients of the other parameter numbers become invalid.)
• In case of the following settings, scaling is performed using the compensation coefficient of
parameter 1 for “Z” of parameters 1, 2, and 4. (The compensation coefficients of parameters 2
and 4 become invalid.)
Reference value 1
Display Parameter Setting Compensation Coefficient Setting
Parameter 1: Z a = 1.500, b = 1.50000
Parameter 2: Z a = 1.700, b = 2.50000
Parameter 3: θ a = 0.700, b = 1.00000
Parameter 4: Z a = 1.900, b = 3.50000
5.5 Troubleshooting of Compensation
When an error occurs in calibration or compensation measurement
If [RdcLIMIT] has been set, an error occurs during measurement when wrong standard units are
connected. Check the type to execute (OPEN/SHORT/LOAD) with the standard unit.
In case of unusual measured values after compensation
Compensation may have been performed with wrong standard units connected during calibration
and compensation.
See “Prevention of improper standard unit connection” (p. 150).
