3.2. Description of Controls 1 / 2. Output Terminals Output Voltage and Current is available on two front panel terminals which are suitable for either wire compression or 4mm 'wander' plug insertion. 3. Polarity Switch Normal or reverse polarity is selected by a toggle switch. The centre position is OFF which provides an open circuit on the output terminals. -
Page 8: Operation
4. Operation 4.1. Voltage Ranges Suggested operation procedure is as follows: Select Off position on output switch. Turn on, and select required range. Check battery level indicator for high enough reading (see ‘Battery Replacement’). Select required output on the ten turn potentiometer, which can then be locked by pushing the lever at the bottom to the left. -
Page 9: Current Ranges
4.3. Current Ranges On the current ranges, the drive voltage available at the terminals is governed by the battery voltage. Care should be taken not to exceed the 1030 voltage limit, as large errors will result if the load/current product exceeds the 1030 8V drive capability. This can easily be checked by either measuring the voltage across the 1030’s terminals when under load, or by checking that R x I is less than 8 volts. -

Four Terminal Resistance Measurements Accurate measurements of low ohm values, such as P.R.T, can be performed by using the 1030 as a current source and measuring the voltage across the LOAD with a DVM.

Page 11: Thermocouple Simulation
5.2 Thermocouple Simulation The 10mV range of the 1030 is ideal for simulation of all types of thermocouple. Just find the voltage required from the British Standard tables, (common values given below), and set up on the 1030’s dial. Do not forget to allow for the Cold Junction temperature. -

6. B attery R eplac ement & R ec harging The battery capacity for rechargeable types is approx. 110mAH, whereas non- rechargeable types are approx. 70mAH. The 1030 circuitry takes 2mA, and will operate over a battery voltage range of 7-12 volts. The battery life is primarily dependent on the output current used. -
Page 13: C Alibration
7. C alibration The instrument is calibrated before it leaves the factory and the calibration controls will not normally require adjustment. If re-adjustment is considered necessary, and the trimmer range is found to be insufficient for recalibration, there is a fault with the instrument. To calibrate the instrument a DVM of 0.1% accuracy is required. -
Page 14: Module And Trimmer Location
7.2. Module and Trimmer Location Fig. 2 Turn the output adjustment pot. to full scale, and adjust the full scale calibration trimmer until the DVM reads 100mV. The full scale for the instrument is then set up correctly. The other ranges do not normally require calibration, and therefore are not fitted with trimmers. -
