OPERATION
3.1 Initial Inspection and Setup
This instrument was carefully inspected before ship-
ment. It should be in proper electrical and mechanical
order upon receipt.
To provide ready reference to specifi cations, a label,
shown in Figure 2-1, is attached to the case of the
instrument.
3.2 Connections to Capacitor
All 1404 capacitors have 2 bnc connectors labeled
HI and LO , as shown in fi gure 3-1.

3.3 Temperature Coeffi cient
Temperature coeffi cients are given on the certifi cate
of calibration and the label attached to the standards.
It is important to consider the TC of the 1404 when
measuring at temperatures other than 23°C.
