Modes of Operation Can source or load with the ranges 0- 10 mA (10 pA resolution) 4 - 20 mA (10 uA resolution) Accuracy + 0.1% of full scale both ranges Linearity + 0.15% both ranges Temperature Coefficient 150 ppm per °C Output Noise 30 ppm of full scale Battery Condition Continuously monitored by a battery level meter Maximum Output Voltage 27 V maximum Battery 3 off PP3 type batteries. Battery life is approximately 30 hours. An alternative power source would be 3 Ni-Cad PP3 batteries. These can be recharged, with a suitable charger, via the recharge socket. Protection The 1033 can withstand open circuits, short circuits and reverse polarity up to 50 V in the load mode. Voltage Limit An LED provides a warning of insufficient drive voltage. Construction The 1033 is constructed in a durable plastic case. Internally the circuit is buiit on a compact PCB, with a plug in reference module. A carry case is also supplied General Information Dimensions. 120 x 65 x 65 mm Weight 330g Optional Extras Rechargeable Battery Pack: 3 Ni-Cad Batteries and 240 V mains charger.
