PROCESSOR CONTROLLED DIGITAL OHMMETER PO-02
	power source: accumulator 4.8 V measurement range 0.0 - 5000.0 Ohm dimensions 85 x 85 x 30 mm measurement current: max 0.5 mA protection IP 65 in addition to basic functionality also provides basic calculations and various recommendations provides all technical and data information when connected to VTR-2 and VTR-1a compliant with EU standards + accumulator charger

Description:

• Designed to measure active resistance of detonation networks at blasting operations with maximal resistance up to 5000 ohm without switching measuring range with accuracy of one decimal place.
• Designed for use on ground, underground and in explosive environments.
• Fully compatible with VTR-2 blasting machine and alarm siren PS-125.
• 16 digit display located on front side under transparent cover which performs several functions according to the connection.
• it's possible to readout measured resistance when blasting circuit wires (measured resistance) are connected to clamps and ratios are stabilized (cca 5 seconds).
• After holding a measured value for adjusted period (minimum is 10 seconds) will display some technical informations in form of recommendation of convenient detonator for measured resistance and number of detonators SO and Sicca.
• Displays accumulator capacity status and recharging progress when connected to the accumulator charger.
• Automaticaly switches to communication mode when connected to VTR-2 blasting machine and displays programmed informations about VTR-2. The same applies to alarm siren PS-125 and innovated VTR-1 blasting machine.
• Correct instrument functionality and accumulator check is realised by shorting the measuring clamps with convenient wire and consecutive readout of displayed values.
• Power supplied by rechargeable accumulator 4.8 V
