Page 4: Introduction
The 7015 can operate for 24 hrs of typical use from the internal batteries. Full recharge can be done overnight - connect the mains power and the internal charger will recharge the battery. -
Page 5: Electrical Signals
Continuity threshold is 100 ohms and values below this are indicated by an internal buzzer and by ‘CONTINUITY’ appearing on the mA display. All electrical connections to the 7015 are via colour coded industry standard 4mm terminal posts. These allow a 4mm plug to be inserted or alternatively conventional bare wire connection by clamping under the terminal posts. -
Page 6: Options
User Manual Options For the 7015, input pressure can be generated by external hand pumps. In the field the 7090 pneumatic (vacuum to 40 bar), or 7095 hydraulic (0 to 700 bar) pumps are suitable. Also available are a range of pumps suitable for workshop use, that feature an ergonomic mode of operation. -

Page 11: Operation
Always take care when connecting/disconnecting pressure systems. Pressure Measurement There are two separate pressure channels built into the 7015 (P1 and P2). Operation is the same for both channels and they can be used simultaneously if required. Power on the unit by turning the switch on channel P1 from OFF to the desired units of pressure. -
Page 12: Using The 7015 With An External Hand Pump
Using the 7015 with an External Hand Pump The 7015 can be used with a hand pump up to the maximum pressure/vacuum of the unit. If you are using the Time Electronics 7090 or 7095 pump, it features 2 output ports. Connect one side to the 7015 and the other to the unit under test. -
Page 13: Current Loop Calibration
Time Electronics 7015 Pressure Calibrator User Manual Current Loop Calibration Process control loop currents can be measured and calibrated using the ‘Loop Signal’ mA terminals. Connect the loop current drive supply in series if the loop needs power. The loop signal can be measured on channel P2. -
Page 14: Pressure Transmitter Calibration
Power OFF (auto power down) To switch the 7015 off, rotate pressure select switch to OFF. Ensure the ‘Loop Drive Supply’ switch is also set to centre OFF. The 7015 should always be switched OFF after use to prevent battery discharge. -
Page 15: Power - Mains And Battery
220V, 230V, 240V 110V, 115V IMPORTANT: If a mains supply of 230V is connected to the 7015 when it has been set for 110V operation, the fuse in the fuse carrier will blow. If a mains supply of 110V is connected to the 7015 when it has been set for 230V operation, it will not operate correctly. - Page 16 7015 Pressure Calibrator User Manual Fuses There are three fuses fitted as protection in the 7015, they are standard 20 x 5mm diameter types. Ensure that the correct type and value are fitted as listed below. Mains fuse Type : 20 x 5mm diameter, 1A Quick blow.

Page 17: Operating Precautions And Recommendations
When working with hydraulic systems, it is important to ensure air trapped in the system is minimized by ‘bleeding’. Air can be bled out of the connecting hose at the 7015 end by carefully letting a little fluid dribble out under control of the external cut off valve before connecting the hose to the 7015. -
