Inductance no bar to milliohmmeter
The PC9 digital milliohmmeter from H Tinsley measures resistance over six selectable ranges from 20mohm to 2 kohm.
The PC9 digital milliohmmeter from H Tinsley measures resistance over six selectable ranges from 20mohm to 2 kohm Equally suitable for resistance measurement where inductance is also present, the unit's high sensitivity also enables it to be used for low-resistance work

Four terminals for accurate resistance measurement
H Tinsley has introduced the QJ84 that provides resistance measurement over seven selectable ranges from 20mohm to 20kohm.
Designed for laboratory and test environments, its use covers resistance measurement in cable joints, earth bonds, switches, motors, transformers, generators and other applications.
The six selectable ranges are 20mohm, 200mohm, 2ohm, 20ohm, 200ohm and 2kohm, with accuracy to +/-0.1% at currents up to 1A.
Read-out is on a four-digit LED.
A four-terminal measurement method eliminates errors that would normally occur due to test lead resistance, and the circuitry used achieves measurement much faster than traditional bridge techniques.
Additionally the PC-9 has a range holding facility to further reduce the measurement time for components of similar values.
Internal digital calibration is provided and each unit has a certificate of conformity.
Kelvin-type test leads are supplied.
