Timer Hold HOLD Switch, T–H Key
This function holds the measured value after a time set in advance has
elapsed. You must move away from the place where the meter is located so
that your position or clothes do not have an influence on the measurement.
Setting and holding the time so you may leave the area enable accurate
measurement. The data are held (locked) after five seconds have elapsed.
Operation
1. Press the
HOLD
switch (lock). This causes
D–H
to appear.
2. Press the T–H key to start the timer;
D–H
starts blinking.
3. Move away from the place where the meter is located.
4. When five seconds elapse, a beeping sound is generated, D–H stops
blinking, and the measured value at that time is held (locked).
5. Read the indicated value.
6. To release the lock, press the
HOLD
switch again. This causes
D–H to disappear.
7. To repeat this operation, do items 2 to 5 or 1 to 6.
Range Hold RANGE Key
This key selects automatic range and manual range. Manual range enables
an arbitrarily fixed range to be set. If measured values are known to be
within a particular range response comes fast if a fixed range is used,
making reading much easier.
