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

With Test Leads installed: Press once & Release.
Measurements performed automatically

In conjunction with MODE changes from Auto operation to Continuous

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


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


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


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


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


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.


One 9V alkaline transistor battery; battery life > 50 hours


7.25 in. (184 mm) x 4.3 in, (109 mm) x 1.4 in.
