LCB-1010-B Configuration
This manual contains a description of the three configurations that make up your LCB-1010-B instrument.
Each configuration contains only one leakage current network.
Your instrument is warranted for a period of one year upon shipment of the instrument to the original
purchaser.
Specifications
Each network configuration includes an input fuse to protect against excessive current that could damage the
leakage current network. If the LCB-1010-B is used incorrectly, the internal fusing may not protect the
internal network components from damage. Such damage is not covered under warranty. For continued
protection against risk of fire or electric shock, replace the internal fuse only with a type and rating as
specified in this manual.
Voltage Rating
0-264Vrms AC to enclosure, O.V. Cat II, 50-440Hz at input terminals
1
Current Rating
100mA maximum
Fuse Rating (F1)
Littelfuse 370 series, type TR5, rated 63mA, 250V, fast-acting
2
Environmental
10-90°rH, non-condensing; 0-2000m altitude; 10-40°C
Components
High-frequency, low-parasitic, individually selected to maintain
+/- 1.0% tolerance
Frequency Response
3
50-60 Hz: +/- 3.5% accuracy
>60 Hz – 1MHz: +/- 5% accuracy
Note 1: Current exceeding the current rating will cause the fuse to open
Note 2: Fuse is specified to hold for 1 hour (not open) at 150% of the fuse current rating
Note 3: LCB observed accuracy is in accordance with CTL Decision Sheet no. DSH 251b and e. See
Appendix A for tolerance graphs.
