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 1 TOhm 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, see accessories.
WARNING
OBSERVE ALL MAXIMUM INPUT RATINGS WHEN PERFORMING MEASUREMENTS
The low output can be connected to line earth or allowed to float as selected.
It is recommended that the low is earthed which will help to reduce noise on high ohms and low
current. If allowed to float with respect to line earth the low must remain within 50 volts of line earth.
Outputs are opto-isolated from the interfaces
Input Overloads
If the multimeter is unable to measure the input due to over range, the display will indicate
OVER-RANGE .
