                                 CONTROLS 
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
