The DO7010 microhmmeter has many advanced features including, Auto ranging, Auto power off, Auto measure trigger when leads are connected to the DUT, data logging, replaceable battery pack, Hi-Lo limits , Graphics display with backlight, and built in test resistance for confidence check.
Rechargeable NiMhd batteries means real portability with more than 1000 readings from a single charge, to ensure that downtime is minimised the battery pack can be easily and quickly withdrawn from the front panel and replaced with a fully charged unit, battery charge indicators are provided.
A front panel socket provides a serial RS232 output which may connected direct to a PC or used with the optional remote terminal which will allow operation of the DO7010 up to 15 metres distance.
The DO7010 portable microhmmeter is supplied ready for use with batteries and mains charger and a variety of test lead configurations are offered. For special lead sets we offer a variety of different styles which are listed on the accessories page, together with calibration standards.
