2.4.4.5.RH/TEMP
A 5-pin DIN connector provides the input connection for the Guildline combined
%Relative Humidity and Temperature Environmental sensor (part no. 65220).
2.4.4.6.LINE INPUT CONNECTOR
The
Line Input Connector
is a combination of a 3-prong AC standard male
connector, an ON/OFF switch and a fused input line voltage selector. The input
line's voltage selector consists of a four-position selector and a fuse holder. The
selector allows switching between the four possible settings: 100V, 120V, 220V
and 240V. A 2 Amp time delay fuse is provided for the 100/120 V operation and
a 1 Amp time delay fuse is provided for the 220/240 V operation. The voltage
selector and fuse are set for the 240V operation at the factory (see Section 2.2)
2.4.4.7.EXTERNAL TRIGGER CONNECTOR
This rear panel connector shown in Figure 2-4 works when the TRIGGER
SOURCE is set to external (See Section 4.4.4) to initiate a measurement each
time the EXT TRIG signal pin in the connector is grounded. Internally, the signal
pin (pin 1) of the connector is supplied with +5V through an LED and a 330 Ohm
resistor. Figure 2-5 shows typical external trigger circuits.
2.4.4.8.INTERLOCK CONNECTOR.
This rear panel connector, shown in Figure 2-4 is a dual function connector
containing an interlock control and a Resistivity test fixture Surface/Volume
selection indicator signal.
The interlock control and test fixture status interface connections can be wired
externally as shown in Figure 2-6 for typical Interlock Circuit Configurations.
