2. Specifications
Output: 0.999.9mV in 3 ranges
0.999.9mV in 0.1mV steps
0.99.99mV in 10uV steps
0.0.999mV in 1uV steps
Accuracy:
± 0.02% of setting
± 0.02% of range
Output Resistance:
Less than 0.1 ohm on 1V and 100mV ranges.
1 ohm on 10 mV range.
Maximum Output Current: 1V and 100mV ranges - 20mA.
10mV range: Up to short circuit value although it should be
noted that loads of less than 1K ohm will give greater than
0.1% error.
Output Voltage Stability:
Less than 60ppm/°C.
Less than 100ppm per 3 month. (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 30ppm of f.s.
Reference Source:
Precision zenor diode selected for stability and low
temperature coefficient.
Maximum Overload:
The instrument can withstand continuous short circuit on the
output for all ranges.
Power Supply:
6 AA batteries. A battery condition display indicates 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 re-charger unit are available as an
optional extra.
Null Balance Display:
The null display is on a front panel meter, zero and sensitivity
(1007 only) controls are provided.
Maximum sensitivity: ± 20uV fsd (2uV/div.)
Minimum sensitivity: ± 20-0-20(20 divisions).
Input resistance: Greater than 1M ohm at balance.
Dimensions:
200 x 75 x 110mm (215 x 100 x 120mm incl. protective boot)
Weight:
1.1kg (1.5kg incl. protective boot)
