1.1 Product Overview
This instrument is an insulation ohmmeter that shortens work times
associated with insulation testing. It is not designed for use on
manufacturing lines and should not be used in such applications.
For manufacturing line applications, use the ST5520 Insulation
Tester.
High-speed response
• Considerably improved response time compared to previous models.
• The instrument can be used like models with a meter needle.
Enhanced comparator function
• Can be used similarly to the continuity check with a tester due to judgment
after the start of measurement being extremely short.
• The backlight lights up in red for a FAIL judgment (defective).
Low variation in measured values
• The instrument generates little variation in measured values when used in a
typical measuring environment.
Easy-to-view display
• Backlight source is a white high-intensity LED.
• Wide viewing angle LCD
High-accuracy voltage measurement function
• The instrument incorporates a DC/AC voltmeter with the same accuracy as
a card tester.
• There is no need to switch to a card tester when you need to measure
voltage.
PV
Ω
measurement function (IR4053 and IR4055 only)
• Insulation resistance can be measured accurately for solar battery panel.
