Technical Specifications

Output..................................................................... 0 to 999.9 mV in 3 ranges:

.................................................................................

................................................................................. 1 V range: 0 to 999.9 mV in 0.1 mV steps.

.................................................................................

................................................................................. 100 mV range: 0 to 99.99 mV in 10 µV steps.

................................................................................. 10 mV range: 0 to 9.999 mV in 1 µV steps.

Accuracy ................................................................ ± (0.02 % of setting + 0.02 % of range + 1 µV).

Output resistance.................................................. Less than 0.2 Ω on 1 V and 100 mV ranges. 1 Ω on 10 mV range.

Maximum output current ...................................... 1 V and 100 mV ranges: 20 mA. 10 mV range: Up to short circuit value although

................................................................................. it should be noted that loads of less than 1 kΩ will give greater than 0.1 % error.

Output voltage stability......................................... Less than 60 ppm/°C. Less than 100 ppm per 3 months (non-cumulative).

Operating temperature ......................................... –10 °C to + 60 °C.

Output polarity....................................................... Positive or negative switch selected. A centre ‘off’ position is also provided.

Output noise level ................................................. Less than 30 ppm of full scale.

Reference source .................................................. Precision bandgap reference diode, for stability and low temperature coefficient.

Maximum overload................................................ The instrument can withstand continuous short circuit on the output for all ranges.

Null Balance Display............................................. On a front panel meter, zero and sensitivity controls are provided:

................................................................................. Maximum sensitivity: ± 20 µV f.s.d. ( 3 µV resolution).

................................................................................. Minimum sensitivity: ± 200 mV f.s.d.

................................................................................. Input resistance: Greater than 1 MΩ.

Power supply ......................................................... 6 AA size (51 x 14 mm) batteries. A battery level indicator displays when the batteries

................................................................................. should be changed. An alternative power source is 6 NiMH cells of the same dimensions.

................................................................................. These can be recharged via a socket on the top of the unit.

................................................................................. The 6 rechargeable batteries and mains recharger are available as an optional extra.

General Specification

Weight..................................................................... 0.75 kg (1.2 kg including protective cover).

Optional extras ...................................................... Carry case.

.................................................................................

................................................................................. Rechargeable battery pack with mains charger.

................................................................................. Calibration certificates - traceable (factory) or accredited (ISO 17025).

Country of origin.................................................... UK.
