Compensation • Open and short circuit compensation
• Load circuit compensation
• Cable length compensation
IM3533: 0 m, 1 m (Guaranteed accuracy up to 4 m)
IM3533-01: 0 m, 1 m, 2 m, 4 m
Correlation compensation Enter the compensation coefficients a and b of the following expression.
[Measurement value after compensation] = a × [measurement value] + b
Residual charge protection
function
(Provides protection against
a discharge voltage from a
charged capacitor)
C: Capacitance [F] of test sample
However, V = maximum 400 V
Magnification display
function
The display of measurement values and comparator judgment results can be magnified.
CONTINUOUS
measurement
Perform continuous measurement with saved conditions from the screen.
Display digits setting
function
The number of display digits for measurement values can be set to 3, 4, 5, and 6.
However, the setting differs depending on the parameter. (The initial value is 6 digits)
Display setting function The LCD can be set to ON/OFF.
Key-lock function Can be enabled and disabled by front panel key operation.
Can be enabled and disabled by password input
Trigger synchronous output
function
Applies a measurement signal during analog measurement only.
Panel save and load
function
LCR mode, TRANSFORMER mode: A total of 60 measurement conditions can be saved.
ANALYZER mode: Two measurement conditions can be saved.
Compensation value only: 128 different measurement conditions can be saved.
Any measurement condition can be read by key operation or a control signal via the EXT I/O.
Memory function 32,000 measurement result items can be saved to the instrument.
(Reading via USB, GP-IB, RS-232C and LAN is possible. GP-IB, RS-232C, and LAN inter-
faces are optional.)
Contact check (1) 4-terminal contact check
Performs a contact (disconnection) check between H
CUR
and H
POT
and between L
CUR
and L
POT
.
The threshold can be changed: 1 to 5 (5: high sensitivity, low contact resistance value)
(2) HIGH-Z reject function (detection of OPEN state during 2-terminal measurement)
When the measurement value is higher than the judgment reference, a contact error is
output.
Judgment reference: Can be set to 0% to 30,000% (1% resolution) of range full-scale.
Error output: An error is output from the EXT I/O.
Print function The measurement values can be printed.
*Requires Z3001 RS-232C Interface and RS-232C-compatible printer.
Buzzer sound • The buzzer for the comparator judgment result (IN or NG) can be set to ON/OFF.
• The buzzer sound for key input can be set to ON/OFF.
• Any of four buzzer tones can be selected.
TRANSFORMER Winding ratio (N), mutual inductance (M), and inductance difference (L) can be measured.
Winding ratio (L1: Primary-side L; L2: Secondary-side L)
Mutual inductance (La: In-phase, in-series L; Lb: Reverse-phase, in-series L)
Inductance difference (L1: Primary-side L; L2: Secondary-side L)
