ON/OFF Battery Bus Cut-off |
| Slide Switch ON SIDE OF CASE |
| ON: Energizes instrument and LCD displays Software Version then GO A with AUTO indication (Default) |
| OFF: Isolates battery and DC voltage from instrument controls and circuit. Use for transport and storage |
| TEST Pad |
| With Test Leads installed: Press once & Release |
| Measurements performed automatically |
| In conjunction with MODE changes from Auto operation to Continuous |
| MODE Pad |
| Steps through Auto/Voltage ranges with each press of MODE Pad: |
| AUTO: Default automatic resistance range & Voltage control |
| <10V: Manual Operation 0.01 to = 10V Test Voltage; |
| Resistance Range: 0.01E-1 to 9.99E9 O |
| 10V: Manual Operation at 10V (Nominal, Semi-Constant) |
| Resistance Range: 0.98E4 to 9.99E10 O |
| 100V: Manual Operation at 100V (±<5V) Constant Voltage |
| Resistance Range: 0.98E6 to 9.99E12 O |
| When data in HOLD, press MODE to terminate HOLD without changing operational mode |
| Press MODE with TEST to change from Auto to Continuous |
| Used to measure lead resistance (NULL) |
| Used by Prostat Authorized Technicians for Voltage Calibration |
| CONNECTIONS |
Positive (+): Test Voltage (RED) – Supplies test voltage to electrodes/fixtures |
| Negative (-): Current sensing (BLACK) – Conducts current from electrode, fixtures, or Ground to instrument |
| Chassis: Shielding connection to chassis (WHITE) – Reduces transmitted energy and effect on current measurement |
| Note: ¾ inch spacing between RED and BLACK accommodates dual banana BNC adapters |
| INDICATION |
Colored LED’s indicate instrument operational MODE and Test Voltage (YELLOW) used for the current measurement, as well as measurement completion (GREEN LED) |
| AUTO: ON during automatic operations; OFF in Manual mode |
| <10V |
| 10V |
| 100V |
| GREEN LED: Measurement hold |
| TYPICAL TOLERANCES |
1Nominal performance by range: |
| 0.01E- 1 - 1.0E 0 O <±10%, ±2 Counts |
| 1.0E 0 - 9.99E10 O <±2%, ±2 Counts |
| 1.0E11 - 9.99E12 O <± 10%, ±4 Counts |
| TEST VOLTAGES |
Automatically selected and controlled in AUTO mode. May be manually selected by pressing MODE pad in the following order: |
| <10V Variable based on resistance load: |
| Provides 0.001 to =10V |
| Functional in AUTO within range 0.01 O - <1.0E+4 O |
| Manual Operation Resistance Range: 0.01E-1 to 9.99E+9 O |
| 10V Constant Voltage (Under Load): |
| Test Voltage Varies ± <5% in AUTO or Manual Operations |
| Functional in AUTO within range 1.0E+4O - <1.0E+6 O |
| Manual Operation Resistance Range: 0.9E+4 to 9.99E+10 O |
| 100V Constant Voltage (Under Load): |
| Test Voltage Varies ± <2% in AUTO or Manual Operations |
| Functional in AUTO within range 1.0E+6 O - <1.0E+13 O |
| Manual Operation Resistance Range: 0.90E6 to 9.99E12 O |
| Returns to Auto Mode |
| MODES OF OPERATIONS |
GO A: Performs all automatic and manual voltage select functions, stops and displays measurements after Electrification Period (EP) is complete, then displays data with Green LED ON for 10 seconds |
| GO C: Performs all automatic and manual voltage select functions, continuously displays measurements until the operator presses MODE or TEST pads. GO C disables electrification period controls |
