39G219 Out-of-Circuit Test Lead, LC units
Supplied Out-of-Circuit Test Leads (39G219) - Special low capacity cable with E-Z Hook® clips on one end and BNC on the other end. Connects to the LC103 TEST LEAD jack.
The 39G219 is a supplied accessory for the LC103. It is used for testing capacitors and inductors that are out-of-circuit. The test leads supplied with the LC103 are made of special, low capacity coaxial cable. Using any other cable will add extra capacity to the meter circuits, which may not be within the range of the lead zeroing circuits. Attempting to zero the leads with another, higher capacitance cable connected may cause the DISPLAY to show an error message. This indicates that the value is beyond the zeroing limits of the LC103.
The Out-of-Circuit Test Leads used with the LC103 have a small amount of capacitance, resistance, and inductance. These must be balanced out before measuring small value capacitors and inductors or before measuring capacitor ESR. The test lead impedance should be zeroed when the LC103 is first turned on. It remains zeroed as long as the unit is powered on. If the LC103 is battery operated and is turned off by the auto-off circuits, however, the leads must be re-zeroed. You will need to re-zero the leads when switching from the in-circuit to out-of-circuit leads and vice-versa.
