It is recommended that the voltage and low current leads be high quality screened
cable with gold plated 4mm plugs fitted. The cable must be able to withstand 1025
volts AC and have an insulation resistance greater than 1T
 to avoid introducing
any shunting effect on the high resistance ranges.
Poor quality test leads will introduce noise, thermal emf and leakage errors on low
voltage & current ranges and also unstable readings on resistance and capacitance
outputs (see measurement techniques). Special test leads are available from
Transmille for ensuring accurate measurements, see accessories.
Warning: Under no circumstances should any voltage
be connected to the calibrator outputs*. The 1000 Series
calibrator outputs are protected with IGuard however we
advise to be vigilant against accidental connections
* Insulation testers up to 1000V may be connected when using the Insulation test functions
Output Overloads
If the calibrator is unable to drive the load then the output will be turned off and the
calibrator returned to standby mode. The message Standby will be displayed on
the front panel. The output will be automatically reset on setting the output again.
