Accuracy
|
10V and 1V ranges: ± 0.02% of setting + ± 0.005% of range.
100mV range: ± 0.05% of setting + ± 0.005% of range, ± 1µV.
10mV and 1mV ranges: ± 0.05% of setting + ± 0.005% of range, ± 4µV.

|
Output Resistance
|
10V, 1V, and 100mV ranges = less than 0.1Ω (typically 0.05Ω). 10mV and 1mV ranges = 1Ω.
|
|
Maximum Output Current
|
10V, 1V and 100mV ranges = 25mA. 10mV and 1mV ranges = up to short circuit value 30mA, although it should be noted that loads of greater than 1kΩ will give greater than 0.1% error
|
|
Output Voltage Stability
|
Less than 30ppm per °C (0 to +50°C). Less than 5ppm per V variation in supply voltage. Less than 75ppm per year. Less than 10ppm per hour at constant temperature
|
|
Output Polarity
|
Positive or negative switch selected. A centre ‘off’ position is also provided.
|
|
Output Noise Level
|
10V, 1V, and 100mV ranges = less than 10ppm of setting ± 2µV (0 to 10Hz).
10mV and 1mV ranges = less than ± 0.05µV (0 to 10Hz)
|
|
Reference Sources
|
Precision zener diode selected after a special ageing process for a temperature coefficient better than 5ppm per °C and stability better than 10ppm per month, non cumulative.
|
|
Maximum Overload
|
The instrument can withstand continuous short circuit on the output for all ranges.
|
|
Power Supply
|
Time Electronics power unit type PU2 which is housed in the rear of the 1010. The PU2 will power the 1010 direct from the mains or an internal rechargeable battery. The battery is automatically charged when mains power is connected. Access to the power supply is from the back of instrument.

|
Battery Level Indicator
|
A front panel display provides a continuous indication of the battery state.
