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
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
