|Low Test Current DC Low-OHM Meter|
|Ā@Ā@||ĀúCircuit designed to eliminate contact error as
Ā@ much as possible
ĀúMost suitable to measure super-low resistance
Ā@ shunt-resistor, etc.
ĀúMeasurement not to influenced by thermal
Ā@ electro motive force.
ĀúImpressed the measuring current at pulse interval,
Ā@in order to reduce abrasion of measuring terminal.
ĀúContact-check is equipped as standard function.
ĀúMeasuring range : 0.00mÉ∂Ā`15.000kÉ∂
ĀúAvailable to measure the persent the set reference
Ā@ value : 1mÉ∂Ā`10kÉ∂ Ā}50.00%
Ā@ [Minimum resolution of 1É Ohm]
ĀúGP-IB/RS-232C/Centronics output available.[Option]
ĀúComparison result by built-in comparator is
Ā@ open-collector output and displayed as LO, GO, HI by
Ā@ LED and buzzer.
ĀúMeasuring current/voltage-Check are built-in as
Ā@ standard function.
|AX-1155B is available to measure the super-low resistance with high speed
and high accuracy from 0.00mÉ∂
to 15.000É∂(% measurement : 1mÉ∂Ā`10kÉ∂)
In addiition, it is possible tom make the measurement the measuring object accumulately and stable,
because they have DOUBLE MEASURING MODE and special AUTO-ZERO circuit that it is available to
measure them after cancelation of thermoelectromotive force for error factor when the measurement is
made low-resistance especially.
This checker is displayed the measured value, judged HI, GO, and LO, and then the signal is output.
The measuring speed is changeable and it is selectable AVERAGE/DOUBLE/SLOW etc.
And as CONTACT CHECK CIRCUIT and measuring current/abnormal voltage check circuit are equiped as
standard, this checker become higher the confidence.
And it is available to equip the interface of GP-IB, RS-232C, or Centro Output as optional function.
