Analog: AER-13505
Digital: DER-13520

FEATURES:

• Capable of measuring earth voltage
• 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.
• Battery operated
• Auto power off function. The time operates automatically about 3 minutes when the "PUSHBUTTON SWITCH" and "TIMER ON BUTTON" are pressed at the same time to keep the tester power on.
• Data hold function
• Open circuit indication: LED(red) indication when connection with test leads are all correct
• Small and light weight
• Designed to meet IEC-1010 (EN61010) safety standard.

SPECIFICATIONS:
