Precautions
Turn the time set knob gently. Forcing the knob can damage it. The
life of the internal variable resistor is approximately 50 turns. Use an
external variable resistor if frequent adjustment is necessary.
If greater accuracy is required in setting the operation time, mea-
sure the time in advance and adjust it with the knob.
Handle the lead terminals with care.
The operation time will vary with the set value as shown below.

The short time range can be used to more easily set long set values.
Example 1: To set the H3T-A to 10 min, set the time range to 10 s,
Example 2: To set the H3T-B to 5 min, set the time range to 6 s,
The case is made of PBT, which has good resistance to chemicals
and will not be affected if cleaned at room temperature for short
durations of time. The structure of the Unit, however, does not allow
for submersed cleaning.
Models with exposed internal variable resistors can malfunction if
the moving parts come into direct contact with liquid.
Operating
Although leads are plated to allow for soldering temperatures, sol-
range
dering must be performed within 10 s at 260 ¦ 5_C. Solder by hand.
The Unit can be damaged if the terminal pins come into contact with
static electricity on hands or objects during mounting or transport.
Be sure to ground-out static electricity before handling the Unit.
adjust the knob to 10 s, and then change the time
range to 10 min.
adjust the knob to 5 s, and then change the time range
to 6 min.
